CVE-2026-6679

CVE-2026-6679 describes a heap buffer overflow in the DTLS 1.3 ACK serialization path that occurs before the peer is authenticated. The root cause is an integer truncation when computing the length of the ACK record-number list, which leads to an undersized buffer and an overrun. Impact is on wol...

CVE-2026-6679 DTLS 1.3 ACK serialization heap buffer overflow via integer truncation

A heap buffer overflow could occur in the DTLS 1.3 ACK serialization path before the connecting peer is authenticated. The buffer overflow was due to an integer truncation when computing the length of the ACK record-number list, causing an undersized buffer to be allocated and then overrun. This...

gnutls: GnuTLS: Denial of Service via DTLS zero-length fragment

A flaw in GnuTLS DTLS handshake parsing allows malformed fragments with zero length and non-zero offset, leading to an integer underflow during reassembly and resulting in an out-of-bounds read. This issue is remotely exploitable and may cause information disclosure or denial of service...

ALPINE-CVE-2026-54679

jq is a command-line JSON processor. Prior to 1.8.2, on 32bit system, jvpstringappend has a chance of integer/multiple overflowing and then causing a massive buffer overrun. This vulnerability is fixed in 1.8.2...

CVE-2026-53059

A flaw was found in the Linux kernel's device-mapper log dm log component. A local attacker could exploit an integer overflow vulnerability where a 64-bit value is truncated to 32 bits, leading to undersized memory allocations. This allows for out-of-bounds writes to kernel memory during log...

JLSEC-2026-629 Rsync version 3.4.2 and prior contain an integer overflow vulnerability in the compressed-token...

Rsync version 3.4.2 and prior contain an integer overflow vulnerability in the compressed-token decoder where a 32-bit signed counter is not checked for overflow, allowing a malicious sender to trigger an overflow that causes the receiver process to read and return data from outside the intended...

poppler: Integer overflow in Poppler SplashOutputDev::tilingPatternFill leads to heap buffer overflow via unchecked dimension multiplication

A flaw was found in Poppler's Splash backend. A remote attacker could exploit this vulnerability by crafting a malicious PDF file that, when rendered, triggers an integer overflow in the tilingPatternFill function. This overflow leads to an undersized heap memory allocation, allowing a subsequent...

jq: jq: Arbitrary Code Execution or Denial of Service via Signed Integer Overflow

A flaw was found in jq, a tool used for processing JSON data from the command line. A remote attacker can exploit a vulnerability by providing a specially crafted large number as input. This can cause an internal calculation error, leading to a memory overflow where the attacker can write their o...

jq: jq: Denial of Service via integer overflow and buffer overrun on 32-bit systems

A flaw was found in jq, a command-line JSON processor. On 32-bit systems, a local attacker could exploit an integer overflow vulnerability in the jvpstringappend function. This could lead to a massive buffer overrun, resulting in a denial of service DoS condition...

postgresql: integer overflow can cause an undersized allocation and an out-of-bounds write

A flaw was found in PostgreSQL. An integer overflow in multiple server features allows an unprivileged database user to cause an undersized memory allocation that leads to an out-of-bounds write. This issue allows an attacker to execute arbitrary code as the operating system user running the...
