wpa_supplicant: SAE side channel attacks as a result of cache access patterns

The implementations of SAE in hostapd before 2.10 and wpa_supplicant before 2.10 are vulnerable to side channel attacks as a result of cache access patterns. NOTE: this issue exists because of an incomplete fix for CVE-2019-9494.

openjpeg: segmentation fault in opj2_decompress due to uninitialized pointer

A flaw was found in the opj2_decompress program in openjpeg2 2.4.0 in the way it handles an input directory with a large number of files. When it fails to allocate a buffer to store the filenames of the input directory, it calls free() on an uninitialized pointer, leading to a segmentation fault and a denial of service.

Improper Restriction of XML External Entity Reference in liquibase/liquibase

Improper Restriction of XML External Entity Reference in GitHub repository liquibase/liquibase prior to 4.8.0.

When PgBouncer is configured to use "cert" authentication, a man-in-the-middle attacker can inject arbitrary SQL queries when a connection is first established, despite the use of TLS certificate verification and encryption. This flaw affects PgBouncer versions prior to 1.16.1.

openjpeg: heap-buffer-overflow in color.c may lead to DoS or arbitrary code execution

A heap-based buffer overflow was found in openjpeg in color.c:379:42 in sycc420_to_rgb when decompressing a crafted .j2k file. An attacker could use this to execute arbitrary code with the permissions of the application compiled against openjpeg.

edk2: integer underflow in SmmEntryPoint function leads to potential SMM privilege escalation

Existing CommBuffer checks in SmmEntryPoint will not catch underflow when computing BufferSize.

edk2: remote buffer overflow in IScsiHexToBin function in NetworkPkg/IScsiDxe

NetworkPkg/IScsiDxe has remotely exploitable buffer overflows.

openjpeg: out-of-bounds write due to an integer overflow in opj_compress.c

Integer Overflow in OpenJPEG v2.4.0 allows remote attackers to crash the application, causing a Denial of Service (DoS). This occurs when the attacker uses the command line option "-ImgDir" on a directory that contains 1048576 files.

poppler: NULL pointer dereference in `FoFiType1C::convertToType1`

An issue was discovered in freedesktop poppler version 20.12.1, allows remote attackers to cause a denial of service (DoS) via crafted .pdf file to FoFiType1C::convertToType1 function.

Underflow in PHP-FPM can lead to RCE

In PHP versions 7.1.x below 7.1.33, 7.2.x below 7.2.24 and 7.3.x below 7.3.11 in certain configurations of FPM setup it is possible to cause FPM module to write past allocated buffers into the space reserved for FCGI protocol data, thus opening the possibility of remote code execution.

Directory Traversal with spring-cloud-config-server

Spring Cloud Config, versions 2.2.x prior to 2.2.3, versions 2.1.x prior to 2.1.9, and older unsupported versions allow applications to serve arbitrary configuration files through the spring-cloud-config-server module. A malicious user, or attacker, can send a request using a specially crafted URL that can lead to a directory traversal attack.

AddressSanitizer: stack-buffer-overflow in jq_fuzz_execute (jv_string_vfmt)

jq is a command-line JSON processor. In versions up to and including 1.7.1, a heap-buffer-overflow is present in function `jv_string_vfmt` in the jq_fuzz_execute harness from oss-fuzz. This crash happens on file jv.c, line 1456 `void* p = malloc(sz);`. As of time of publication, no patched versions are available.

corosync: Stack buffer overflow from 'orf_token_endian_convert'

Corosync through 3.1.9, if encryption is disabled or the attacker knows the encryption key, has a stack-based buffer overflow in orf_token_endian_convert in exec/totemsrp.c via a large UDP packet.

SQUID-2021:8 Denial of Service in Gopher gateway

Squid is a caching proxy for the Web supporting HTTP, HTTPS, FTP, and more. Due to a NULL pointer dereference bug Squid is vulnerable to a Denial of Service attack against Squid's Gopher gateway. The gopher protocol is always available and enabled in Squid prior to Squid 6.0.1. Responses triggering this bug are possible to be received from any gopher server, even those without malicious intent. Gopher support has been removed in Squid version 6.0.1. Users are advised to upgrade. Users unable to upgrade should reject all gopher URL requests.

Ceph: ceph-crash.service allows local ceph user to root exploit

A privilege escalation flaw was found in Ceph. Ceph-crash.service allows a local attacker to escalate privileges to root in the form of a crash dump, and dump privileged information.

ceph: Ceph volume does not honour osd_dmcrypt_key_size

A key length flaw was found in Red Hat Ceph Storage. An attacker can exploit the fact that the key length is incorrectly passed in an encryption algorithm to create a non random key, which is weaker and can be exploited for loss of confidentiality and integrity on encrypted disks.

luajit: out-of-bounds read because __gc handler frame traversal is mishandled

LuaJit through 2.1.0-beta3 has an out-of-bounds read because __gc handler frame traversal is mishandled.

GIMP ICO File Parsing Integer Overflow Remote Code Execution Vulnerability

GIMP ICO File Parsing Integer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GIMP. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of ICO files. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before writing to memory. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-26752.

raptor: integer underflow when normalizing a URI with the turtle parser

In Raptor RDF Syntax Library through 2.0.16, there is an integer underflow when normalizing a URI with the turtle parser in raptor_uri_normalize_path().

Mercurial configuration injectable in repo revision when installing via pip

When installing a package from a Mercurial VCS URL (ie "pip install hg+...") with pip prior to v23.3, the specified Mercurial revision could be used to inject arbitrary configuration options to the "hg clone" call (ie "--config"). Controlling the Mercurial configuration can modify how and which repository is installed. This vulnerability does not affect users who aren't installing from Mercurial.
