There is a possible information disclosure issue in Active Resource <v5.1.1 that could allow an attacker to create specially crafted requests to access data in an unexpected way and possibly leak information.

MariaDB v10.4 to v10.7 was discovered to contain an use-after-poison in prepare_inplace_add_virtual at /storage/innobase/handler/handler0alter.cc.

The CSSParser::parseFontFaceSrc function in WebCore/css/CSSParser.cpp in WebKit, as used in Google Chrome before 8.0.552.224, Chrome OS before 8.0.552.343, webkitgtk before 1.2.6, and other products does not properly parse Cascading Style Sheets (CSS) token sequences, which allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted local font, related to "Type Confusion."

named may terminate unexpectedly under high DNS-over-TLS query load

A denial-of-service vulnerability exists in the WS-Addressing plugin functionality of Genivia gSOAP 2.8.107. A specially crafted SOAP request can lead to denial of service. An attacker can send an HTTP request to trigger this vulnerability.

Regular Expression Denial of Service in Addressable templates

MariaDB v10.5 to v10.7 was discovered to contain a segmentation fault via the component st_select_lex_unit::exclude_level.

An issue was discovered in HAProxy 2.2 before 2.2.16, 2.3 before 2.3.13, and 2.4 before 2.4.3. It can lead to a situation with an attacker-controlled HTTP Host header, because a mismatch between Host and authority is mishandled.

An issue was discovered in adns before 1.5.2. adnshost mishandles a missing final newline on a stdin read. It is wrong to increment used as well as setting r, since used is incremented according to r, later. Rather one should be doing what read() would have done. Without this fix, adnshost may read and process one byte beyond the buffer, perhaps crashing or perhaps somehow leaking the value of that byte.

The mod_dialback module in Prosody before 0.9.9 does not properly generate random values for the secret token for server-to-server dialback authentication, which makes it easier for attackers to spoof servers via a brute force attack.

An issue was discovered in HAProxy 2.2 before 2.2.16, 2.3 before 2.3.13, and 2.4 before 2.4.3. It does not ensure that the scheme and path portions of a URI have the expected characters. For example, the authority field (as observed on a target HTTP/2 server) might differ from what the routing rules were intended to achieve.

regexp.c in Artifex Software, Inc. MuJS allows attackers to cause a denial of service (NULL pointer dereference and crash) via vectors related to regular expression compilation.

The JWT library in NATS nats-server before 2.1.9 allows a denial of service (a nil dereference in Go code).

An issue was discovered in Xen through 4.12.x allowing x86 HVM/PVH guest OS users to cause a denial of service (guest OS crash) because VMX VMEntry checks mishandle a certain case. Please see XSA-260 for background on the MovSS shadow. Please see XSA-156 for background on the need for #DB interception. The VMX VMEntry checks do not like the exact combination of state which occurs when #DB in intercepted, Single Stepping is active, and blocked by STI/MovSS is active, despite this being a legitimate state to be in. The resulting VMEntry failure is fatal to the guest. HVM/PVH guest userspace code may be able to crash the guest, resulting in a guest Denial of Service. All versions of Xen are affected. Only systems supporting VMX hardware virtual extensions (Intel, Cyrix, or Zhaoxin CPUs) are affected. Arm and AMD systems are unaffected. Only HVM/PVH guests are affected. PV guests cannot leverage the vulnerability.

An issue found in Frrouting bgpd v.8.4.2 allows a remote attacker to cause a denial of service via the bgp_attr_psid_sub() function.

Crash in the Gryphon dissector in Wireshark 3.4.0 to 3.4.10 allows denial of service via packet injection or crafted capture file

Protocol vs scheme mismatch

The CentralNotice extension for MediaWiki before 1.19.9, 1.20.x before 1.20.8, and 1.21.x before 1.21.3 sets the Cache-Control header to cache session cookies when a user is autocreated, which allows remote attackers to authenticate as the created user.

389 Directory Server before 1.3.3.10 allows attackers to bypass intended access restrictions and modify directory entries via a crafted ldapmodrdn call.

Moodle has a database activity export permission issue where the export function of the database activity module exports all entries even those from groups the user does not belong to

Moodle before 2.2.2 has users' private files included in course backups

Uncontrolled Resource Consumption in cmark-gfm

Xpdf 4.02 allows stack consumption because of an incorrect subroutine reference in a Type 1C font charstring, related to the FoFiType1C::getOp() function.

There is a DoS vulnerability in Pillow before 6.2.2 caused by FpxImagePlugin.py calling the range function on an unvalidated 32-bit integer if the number of bands is large. On Windows running 32-bit Python, this results in an OverflowError or MemoryError due to the 2 GB limit. However, on Linux running 64-bit Python this results in the process being terminated by the OOM killer.

Botan 1.11.x before 1.11.29 does not enforce TLS policy for (1) signature algorithms and (2) ECC curves, which allows remote attackers to conduct downgrade attacks via unspecified vectors.

An issue was discovered in Prosody before 0.11.9. Default settings are susceptible to remote unauthenticated denial-of-service (DoS) attacks via memory exhaustion when running under Lua 5.2 or Lua 5.3.

MariaDB v10.5 to v10.7 was discovered to contain an assertion failure at table->get_ref_count() == 0 in dict0dict.cc.

An issue was discovered in Artifex MuJS 1.0.5. jscompile.c can cause a denial of service (invalid stack-frame jump) because it lacks an ENDTRY opcode call.

In Wireshark 3.2.0 to 3.2.7, the GQUIC dissector could crash. This was addressed in epan/dissectors/packet-gquic.c by correcting the implementation of offset advancement.

SQL injection vulnerability in OpenVAS Manager before 4.0.6 and 5.x before 5.0.7 allows remote attackers to execute arbitrary SQL commands via the timezone parameter in a modify_schedule OMP command.

The Tungstenite crate before 0.20.1 for Rust allows remote attackers to cause a denial of service (minutes of CPU consumption) via an excessive length of an HTTP header in a client handshake. The length affects both how many times a parse is attempted (e.g., thousands of times) and the average amount of data for each parse attempt (e.g., millions of bytes).

Suricata before 5.0.7 and 6.x before 6.0.3 has a "critical evasion."

In GNOME Epiphany before 41.4 and 42.x before 42.2, an HTML document can trigger a client buffer overflow (in ephy_string_shorten in the UI process) via a long page title. The issue occurs because the number of bytes for a UTF-8 ellipsis character is not properly considered.

libexpat through 2.6.1 allows an XML Entity Expansion attack when there is isolated use of external parsers (created via XML_ExternalEntityParserCreate).

Tcpreplay version 4.4.1 contains a memory leakage flaw in fix_ipv6_checksums() function. The highest threat from this vulnerability is to data confidentiality.

Apache Traffic Server: Configuration option to block the PUSH method in ATS didn't work

In the standard library in Rust before 1.52.0, the Zip implementation calls __iterator_get_unchecked() more than once for the same index (under certain conditions) when next_back() and next() are used together. This bug could lead to a memory safety violation due to an unmet safety requirement for the TrustedRandomAccess trait.

A vulnerability was discovered in DNS resolver component of knot resolver through version 3.2.0 before 4.1.0 which allows remote attackers to bypass DNSSEC validation for non-existence answer. NXDOMAIN answer would get passed through to the client even if its DNSSEC validation failed, instead of sending a SERVFAIL packet. Caching is not affected by this particular bug but see CVE-2019-10191.

A memory leak was found in Open vSwitch (OVS) during userspace IP fragmentation processing. An attacker could use this flaw to potentially exhaust available memory by keeping sending packet fragments.

A vulnerability found in gnutls. This security flaw happens because of a double free error occurs during verification of pkcs7 signatures in gnutls_pkcs7_verify function.
