A malicious or compromised PostgreSQL server can send a DataRow message with a negative field length, resulting in a slice bounds o...

postgresql: PostgreSQL missing validation of multibyte character length executes arbitrary code

Missing validation of multibyte character length in PostgreSQL text manipulation allows a database user to issue crafted queries that achieve a buffer overrun. That suffices to execute arbitrary code as the operating system user running the database...

389-ds-base: 389-ds-base: Remote Code Execution and Denial of Service via heap buffer overflow

A flaw was found in the 389-ds-base server. A heap buffer overflow vulnerability exists in the schemaattrenumcallback function within the schema.c file. This occurs because the code incorrectly calculates the buffer size by summing alias string lengths without accounting for additional formatting...

EUVD-2026-8988

In OCaml before 4.14.3 and 5.x before 5.4.1, a buffer over-read in Marshal deserialization runtime/intern.c enables remote code execution through a multi-phase attack chain. The vulnerability stems from missing bounds validation in the readblock function, which performs unbounded memcpy operation...

CVE-2026-2597

Crypt::SysRandom::XS versions before 0.010 for Perl is vulnerable to a heap buffer overflow in the XS function randombytes. The function does not validate that the length parameter is non-negative. If a negative value e.g. -1 is supplied, the expression length + 1u causes an integer wraparound,...

This update for postgresql17 fixes the following issues: Update to version 17.8. Security issues fixed: - CVE-2026-2003: improper validation of type 'oidvector' may allow disclose a few bytes of server memory bsc1258008. - CVE-2026-2004: intarray missing validation of type of input to selectivity...

Integer Overflow or Wraparound

Overview Affected versions of this package are vulnerable to Integer Overflow or Wraparound via the readPropertySeq function when handling manipulated DATA Submessages with tampered length fields in the PIDIDENTITYTOKEN or PIDPERMISSIONTOKEN fields. An attacker can cause a remote out-of-memory...

openssl: OpenSSL: Information disclosure and data tampering via specific low-level OCB encryption/decryption calls

A flaw was found in OpenSSL. When applications directly call the low-level CRYPTOocb128encrypt or CRYPTOocb128decrypt functions with non-block-aligned lengths in a single call on hardware-accelerated builds, the trailing 1-15 bytes of a message may be exposed in cleartext. These exposed bytes are...
