postgresql: PostgreSQL: Arbitrary code execution via long POSIX timezone abbreviation

A heap buffer overflow flaw was found in the PostgreSQL tochartimestamptz function. An attacker can exploit this by supplying an overly long POSIX timezone abbreviation to execute arbitrary code as the database's operating system user, potentially resulting in complete system compromise...

postgresql: PostgreSQL: Arbitrary code execution via heap buffer overflow in regexp

A flaw was found in PostgreSQL. A heap buffer overflow vulnerability exists in the regexp component, which can be triggered by a query author providing text that does not pass encoding validation. This can lead to unanticipated data growth, allowing the attacker to execute arbitrary code as the...

postgresql: PostgreSQL: Arbitrary code execution via plperl tied hash heap buffer overflow

A flaw was found in PostgreSQL. A heap buffer overflow vulnerability exists in the plperl component when returning a tied hash. This allows a function owner to execute arbitrary code as the operating system user running the database by providing a specially crafted function body. This could lead ...

postgresql: PostgreSQL pg_dump: Arbitrary code execution via crafted transform lists

A flaw was found in PostgreSQL pgdump. A heap buffer overflow vulnerability exists when processing long function transform lists. An authenticated object creator can exploit this by providing a specially crafted transform list. This allows the attacker to execute arbitrary code as the operating...

SUSE CVE-2026-63273

LibreOffice Draw can import PDF documents. A heap buffer overflow existed when importing an encrypted document. The length of the decryption key was taken from the document's own encryption dictionary and was used to fill a fixed size key buffer without being checked against it, so a length large...

CVE-2026-91815: Out-of-bounds Write

Foxit PDF Editor/Reader does not perform sufficient verification of the JPEG2000 image metadata in the PDF file, which leads to out-of-bounds write in the heap buffer during decoding, potentially causing the program to crash and introducing the risk of arbitrary code execution...

CVE-2026-86926: Heap-based Buffer Overflow

A heap buffer overflow vulnerability in the FileMaker Server database engine block parsing routine allowed a maliciously crafted .fmp12 database file to cause memory corruption, potentially leading to arbitrary code execution. This vulnerability is addressed in FileMaker Server version 26.0.3...
