Red Hat Enterprise Linux 5.0

It was found that when Artemis and HornetQ before 2.4.0 are configured with UDP discovery and JGroups discovery a huge byte array is created when receiving an unexpected multicast message. This may result in a heap memory exhaustion, full GC, or OutOfMemoryError.

The error function in Error.cc in poppler before 0.21.4 allows remote attackers to execute arbitrary commands via a PDF containing an escape sequence for a terminal emulator.

In ghostscript before version 9.50, the .buildfont1 procedure did not properly secure its privileged calls, enabling scripts to bypass `-dSAFER` restrictions. An attacker could abuse this flaw by creating a specially crafted PostScript file that could escalate privileges and access files outside of restricted areas.

PyXML: Hash table collisions CPU usage Denial of Service

It was found that in ghostscript some privileged operators remained accessible from various places after the CVE-2019-6116 fix. A specially crafted PostScript file could use this flaw in order to, for example, have access to the file system outside of the constrains imposed by -dSAFER. Ghostscript versions before 9.27 are vulnerable.

Netwide Assembler (NASM) 2.14rc15 has a heap-based buffer over-read in expand_mmac_params in asm/preproc.c for insufficient input.

Netwide Assembler (NASM) 2.14rc16 has a heap-based buffer over-read in expand_mmac_params in asm/preproc.c for the special cases of the % and $ and ! characters.

scripts/xzgrep.in in xzgrep 5.2.x before 5.2.0, before 5.0.0 does not properly process file names containing semicolons, which allows remote attackers to execute arbitrary code by having a user run xzgrep on a crafted file name.

There is heap-based buffer overflow in kernel, all versions up to, excluding 5.3, in the marvell wifi chip driver in Linux kernel, that allows local users to cause a denial of service(system crash) or possibly execute arbitrary code.

The Tomcat package on Red Hat Enterprise Linux (RHEL) 5 through 7, JBoss Web Server 3.0, and JBoss EWS 2 uses weak permissions for (1) /etc/sysconfig/tomcat and (2) /etc/tomcat/tomcat.conf, which allows local users to gain privileges by leveraging membership in the tomcat group.

The SQLDriverConnect() function in unixODBC before 2.2.14p2 have a possible buffer overflow condition when specifying a large value for SAVEFILE parameter in the connection string.

The KVM subsystem in the Linux kernel before 3.0 does not check whether kernel addresses are specified during allocation of memory slots for use in a guest's physical address space, which allows local users to gain privileges or obtain sensitive information from kernel memory via a crafted application, related to arch/x86/kvm/paging_tmpl.h and virt/kvm/kvm_main.c.

Linux kernel: heap out-of-bounds in AF_PACKET sockets. This new issue is analogous to previously disclosed CVE-2016-8655. In both cases, a socket option that changes socket state may race with safety checks in packet_set_ring. Previously with PACKET_VERSION. This time with PACKET_RESERVE. The solution is similar: lock the socket for the update. This issue may be exploitable, we did not investigate further. As this issue affects PF_PACKET sockets, it requires CAP_NET_RAW in the process namespace. But note that with user namespaces enabled, any process can create a namespace in which it has CAP_NET_RAW.

frysk packages through 2008-08-05 as shipped in Red Hat Enterprise Linux 5 are built with an insecure RPATH set in the ELF header of multiple binaries in /usr/bin/f* (e.g. fcore, fcatch, fstack, fstep, ...) shipped in the package. A local attacker can exploit this vulnerability by running arbitrary code as another user.

The DES and Triple DES ciphers, as used in the TLS, SSH, and IPSec protocols and other protocols and products, have a birthday bound of approximately four billion blocks, which makes it easier for remote attackers to obtain cleartext data via a birthday attack against a long-duration encrypted session, as demonstrated by an HTTPS session using Triple DES in CBC mode, aka a "Sweet32" attack.

SACK can cause extensive memory use via fragmented resend queue

A use-after-free vulnerability in SVG Animation has been discovered. An exploit built on this vulnerability has been discovered in the wild targeting Firefox and Tor Browser users on Windows. This vulnerability affects Firefox < 50.0.2, Firefox ESR < 45.5.1, and Thunderbird < 45.5.1.

Integer overflow in the vclmi.dll module in OpenOffice.org (OOo) 3.3, 3.4 Beta, and possibly earlier, and LibreOffice before 3.5.3, allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a crafted embedded image object, as demonstrated by a JPEG image in a .DOC file, which triggers a heap-based buffer overflow.

Buffer overflow in pattern.c in libxslt before 1.1.24 allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via an XSL style sheet file with a long XSLT "transformation match" condition that triggers a large number of steps.

Directory traversal vulnerability in slp.c in the MSN protocol plugin in libpurple in Pidgin 2.6.4 and Adium 1.3.8 allows remote attackers to read arbitrary files via a .. (dot dot) in an application/x-msnmsgrp2p MSN emoticon (aka custom smiley) request, a related issue to CVE-2004-0122. NOTE: it could be argued that this is resultant from a vulnerability in which an emoticon download request is processed even without a preceding text/x-mms-emoticon message that announced availability of the emoticon.

Multiple buffer overflows in the (1) png_set_PLTE and (2) png_get_PLTE functions in libpng before 1.0.64, 1.1.x and 1.2.x before 1.2.54, 1.3.x and 1.4.x before 1.4.17, 1.5.x before 1.5.24, and 1.6.x before 1.6.19 allow remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a small bit-depth value in an IHDR (aka image header) chunk in a PNG image.

External resources that should be blocked when loaded by SVG images can bypass security restrictions through the use of "data:" URLs. This could allow for cross-domain data leakage. This vulnerability affects Firefox < 50.1, Firefox ESR < 45.6, and Thunderbird < 45.6.

cyrus-sasl (aka Cyrus SASL) 2.1.27 has an out-of-bounds write leading to unauthenticated remote denial-of-service in OpenLDAP via a malformed LDAP packet. The OpenLDAP crash is ultimately caused by an off-by-one error in _sasl_add_string in common.c in cyrus-sasl.

dom4j version prior to version 2.1.1 contains a CWE-91: XML Injection vulnerability in Class: Element. Methods: addElement, addAttribute that can result in an attacker tampering with XML documents through XML injection. This attack appear to be exploitable via an attacker specifying attributes or elements in the XML document. This vulnerability appears to have been fixed in 2.1.1 or later.

Buffer overflow in the polymorphic opcode support in the Regular Expression Engine (regcomp.c) in Perl 5.8 allows context-dependent attackers to execute arbitrary code by switching from byte to Unicode (UTF) characters in a regular expression.

Use-after-free vulnerability in the abstract file-descriptor handling interface in the cupsdDoSelect function in scheduler/select.c in the scheduler in cupsd in CUPS 1.3.7 and 1.3.10 allows remote attackers to cause a denial of service (daemon crash or hang) via a client disconnection during listing of a large number of print jobs, related to improperly maintaining a reference count. NOTE: some of these details are obtained from third party information.

Hashed codes of JavaScript objects are shared between pages. This allows for pointer leaks because an object's address can be discovered through hash codes, and also allows for data leakage of an object's content using these hash codes. This vulnerability affects Thunderbird < 45.7, Firefox ESR < 45.7, and Firefox < 51.

A flaw was found in OpenLDAP in versions before 2.4.56. This flaw allows an attacker who sends a malicious packet processed by OpenLDAP to force a failed assertion in csnNormalize23(). The highest threat from this vulnerability is to system availability.

tog-Pegasus has a package hash collision DoS vulnerability

A certain Red Hat build script for nfs-utils before 1.0.9-35z.el5_2 on Red Hat Enterprise Linux (RHEL) 5 omits TCP wrappers support, which might allow remote attackers to bypass intended access restrictions.

Use-after-free vulnerability in the abstract file-descriptor handling interface in the cupsdDoSelect function in scheduler/select.c in the scheduler in cupsd in CUPS before 1.4.4, when kqueue or epoll is used, allows remote attackers to cause a denial of service (daemon crash or hang) via a client disconnection during listing of a large number of print jobs, related to improperly maintaining a reference count. NOTE: some of these details are obtained from third party information. NOTE: this vulnerability exists because of an incomplete fix for CVE-2009-3553.

Same-origin policy protections can be bypassed on pages with embedded iframes during page reloads, allowing the iframes to access content on the top level page, leading to information disclosure. This vulnerability affects Thunderbird < 52.3, Firefox ESR < 52.3, and Firefox < 55.

Off-by-one error in the QUtf8Decoder::toUnicode function in Trolltech Qt 3 allows context-dependent attackers to cause a denial of service (crash) via a crafted Unicode string that triggers a heap-based buffer overflow. NOTE: Qt 4 has the same error in the QUtf8Codec::convertToUnicode function, but it is not exploitable.

A Null pointer dereference vulnerability exists in Mozilla Network Security Services due to a missing NULL check in PK11_SignWithSymKey / ssl3_ComputeRecordMACConstantTime, which could let a remote malicious user cause a Denial of Service.

WebExtension scripts can use the "data:" protocol to affect pages loaded by other web extensions using this protocol, leading to potential data disclosure or privilege escalation in affected extensions. This vulnerability affects Firefox ESR < 45.7 and Firefox < 51.

A NULL pointer dereference was found in OpenLDAP server and was fixed in openldap 2.4.55, during a request for renaming RDNs. An unauthenticated attacker could remotely crash the slapd process by sending a specially crafted request, causing a Denial of Service.

An access bypass issue was found in Drupal 7.x before version 7.5. If a Drupal site has the ability to attach File upload fields to any entity type in the system or has the ability to point individual File upload fields to the private file directory in comments, and the parent node is denied access, non-privileged users can still download the file attached to the comment if they know or guess its direct URL.

GnuTLS before 3.3.13 does not validate that the signature algorithms match when importing a certificate.

PHP5 before 5.4.4 allows passing invalid utf-8 strings via the xmlTextWriterWriteAttribute, which are then misparsed by libxml2. This results in memory leak into the resulting output.
