In versions of mruby up to and including 1.4.0, an integer overflow exists in src/vm.c::mrb_vm_exec() when handling OP_GETUPVAR in the presence of deep scope nesting, resulting in a use-after-free. An attacker that can cause Ruby code to be run can use this to possibly execute arbitrary code.

sysstat through 12.2.0 has a double free in check_file_actlst in sa_common.c.

GDAL through 3.0.1 has a poolDestroy double free in OGRExpatRealloc in ogr/ogr_expat.cpp when the 10MB threshold is exceeded.

Mbed TLS before 3.0.1 has a double free in certain out-of-memory conditions, as demonstrated by an mbedtls_ssl_set_session() failure.

The Sympa Community Sympa version prior to version 6.2.32 contains a Directory Traversal vulnerability in wwsympa.fcgi template editing function that can result in Possibility to create or modify files on the server filesystem. This attack appear to be exploitable via HTTP GET/POST request. This vulnerability appears to have been fixed in 6.2.32.

ConnMan (aka Connection Manager) 1.30 through 1.39 has a stack-based buffer overflow in uncompress in dnsproxy.c via NAME, RDATA, or RDLENGTH (for A or AAAA).

FFmpeg before 2017-02-04 has an out-of-bounds write caused by a heap-based buffer overflow related to the decode_frame_common function in libavcodec/pngdec.c.

FFmpeg before 2017-01-24 has an out-of-bounds write caused by a heap-based buffer overflow related to the ipvideo_decode_block_opcode_0xA function in libavcodec/interplayvideo.c and the avcodec_align_dimensions2 function in libavcodec/utils.c.

In GraphicsMagick 1.4 snapshot-20190423 Q8, there is a heap-based buffer overflow in the function ImportRLEPixels of coders/miff.c.

An issue was discovered in Xen through 4.12.x allowing 32-bit PV guest OS users to gain guest OS privileges by installing and using descriptors. There is missing descriptor table limit checking in x86 PV emulation. When emulating certain PV guest operations, descriptor table accesses are performed by the emulating code. Such accesses should respect the guest specified limits, unless otherwise guaranteed to fail in such a case. Without this, emulation of 32-bit guest user mode calls through call gates would allow guest user mode to install and then use descriptors of their choice, as long as the guest kernel did not itself install an LDT. (Most OSes don't install any LDT by default). 32-bit PV guest user mode can elevate its privileges to that of the guest kernel. Xen versions from at least 3.2 onwards are affected. Only 32-bit PV guest user mode can leverage this vulnerability. HVM, PVH, as well as 64-bit PV guests cannot leverage this vulnerability. Arm systems are unaffected.

An issue was discovered in MP4Box in GPAC 0.7.1. The function urn_Read in isomedia/box_code_base.c has a heap-based buffer over-read.

In Dojo Toolkit before 1.14, there is unescaped string injection in dojox/Grid/DataGrid.

Memory safety bugs were reported in Firefox 53 and Firefox ESR 52.1. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. This vulnerability affects Firefox < 54, Firefox ESR < 52.2, and Thunderbird < 52.2.

Memory safety bugs were reported in Thunderbird 45.5. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. This vulnerability affects Firefox < 50.1, Firefox ESR < 45.6, and Thunderbird < 45.6.

During DOM manipulations of the accessibility tree through script, the DOM tree can become out of sync with the accessibility tree, leading to memory corruption and a potentially exploitable crash. This vulnerability affects Thunderbird < 52.1, Firefox ESR < 45.9, Firefox ESR < 52.1, and Firefox < 53.

An issue was discovered in NeoMutt before 2018-07-16. nntp.c proceeds even if memory allocation fails for messages data.

libvncclient/cursor.c in LibVNCServer through 0.9.12 has a HandleCursorShape integer overflow and heap-based buffer overflow via a large height or width value. NOTE: this may overlap CVE-2019-15690.

yum does not properly handle bad metadata, which allows an attacker to cause a denial of service and possibly have other unspecified impact via a Trojan horse file in the metadata of a remote repository.

Stack overflow in PJSUA API when calling pjsua_player_create. An attacker-controlled 'filename' argument may cause a buffer overflow since it is copied to a fixed-size stack buffer without any size validation.

In version 4.8.0 and earlier of The Sleuth Kit (TSK), there is a stack buffer overflow vulnerability in the YAFFS file timestamp parsing logic in yaffsfs_istat() in fs/yaffs.c.

Integer overflow in the htmldoc 1.9.11 and before may allow attackers to execute arbitrary code and cause a denial of service that is similar to CVE-2017-9181.

OpenID Connect Issuer in LemonLDAP::NG 2.x through 2.0.5 may allow an attacker to bypass access control rules via a crafted OpenID Connect authorization request. To be vulnerable, there must exist an OIDC Relaying party within the LemonLDAP configuration with weaker access control rules than the target RP, and no filtering on redirection URIs.

OpenDMARC through 1.3.2 and 1.4.x through 1.4.0-Beta1 is prone to a signature-bypass vulnerability with multiple From: addresses, which might affect applications that consider a domain name to be relevant to the origin of an e-mail message.

There is a heap-based buffer overflow in the pcxLoadRaster function of in_pcx.cpp in sam2p 0.49.4. A crafted input will lead to a denial of service or possibly unspecified other impact.

In libarchive before 3.6.2, the software does not check for an error after calling calloc function that can return with a NULL pointer if the function fails, which leads to a resultant NULL pointer dereference. NOTE: the discoverer cites this CWE-476 remark but third parties dispute the code-execution impact: "In rare circumstances, when NULL is equivalent to the 0x0 memory address and privileged code can access it, then writing or reading memory is possible, which may lead to code execution."

The libtremor library has the same flaw as CVE-2018-5146. This library is used by Firefox in place of libvorbis on Android and ARM platforms. This vulnerability affects Firefox ESR < 52.7.2 and Firefox < 59.0.1.

In Xymon through 4.3.28, a buffer overflow vulnerability exists in history.c.

asyncpg before 0.21.0 allows a malicious PostgreSQL server to trigger a crash or execute arbitrary code (on a database client) via a crafted server response, because of access to an uninitialized pointer in the array data decoder.

A Denial of Service issue was discovered in the LIVE555 Streaming Media libraries as used in Live555 Media Server 0.93. It can cause an RTSPServer crash in handleHTTPCmd_TunnelingPOST, when RTSP-over-HTTP tunneling is supported, via x-sessioncookie HTTP headers in a GET request and a POST request within the same TCP session. This occurs because of a call to an incorrect virtual function pointer in the readSocket function in GroupsockHelper.cpp.

adts_decode_extradata in libavformat/adtsenc.c in FFmpeg 4.4 does not check the init_get_bits return value, which is a necessary step because the second argument to init_get_bits can be crafted.

An issue was discovered in Irssi before 1.0.7 and 1.1.x before 1.1.1. There is a use-after-free when SASL messages are received in an unexpected order.

Cyrus IMAP 2.5.x before 2.5.14 and 3.x before 3.0.12 allows privilege escalation because an HTTP request may be interpreted in the authentication context of an unrelated previous request that arrived over the same connection.

An issue was discovered in Irssi before 1.0.7 and 1.1.x before 1.1.1. There is a use-after-free when a server is disconnected during netsplits. NOTE: this issue exists because of an incomplete fix for CVE-2017-7191.

In Irssi before 1.0.6, a calculation error in the completion code could cause a heap buffer overflow when completing certain strings.

scm/define-stencil-commands.scm in LilyPond through 2.20.0, and 2.21.x through 2.21.4, when -dsafe is used, lacks restrictions on embedded-ps and embedded-svg, as demonstrated by including dangerous PostScript code.

An issue was discovered in uriparser before 0.9.0. UriQuery.c allows an out-of-bounds write via a uriComposeQuery* or uriComposeQueryEx* function because the '&' character is mishandled in certain contexts.

An issue was discovered in LemonLDAP::NG through 2.0.8, when NGINX is used. An attacker may bypass URL-based access control to protected Virtual Hosts by submitting a non-normalized URI. This also affects versions before 0.5.2 of the "Lemonldap::NG handler for Node.js" package.

Stack overflow in PJSUA API when calling pjsua_recorder_create. An attacker-controlled 'filename' argument may cause a buffer overflow since it is copied to a fixed-size stack buffer without any size validation.

Stack overflow in PJSUA API when calling pjsua_playlist_create. An attacker-controlled 'file_names' argument may cause a buffer overflow since it is copied to a fixed-size stack buffer without any size validation.

Buffer overflow in PJSUA API when calling pjsua_call_dump. An attacker-controlled 'buffer' argument may cause a buffer overflow, since supplying an output buffer smaller than 128 characters may overflow the output buffer, regardless of the 'maxlen' argument supplied
