DescriptionCVE.org

Heap buffer overflow in PostgreSQL pg_trgm allows a database user to achieve unknown impacts via a crafted input string. The attacker has limited control over the byte patterns to be written, but we have not ruled out the viability of attacks that lead to privilege escalation. PostgreSQL 18.1 and 18.0 are affected.

AnalysisAI

Heap buffer overflow in the pg_trgm extension of PostgreSQL 18.0 and 18.1 allows authenticated database users to trigger memory corruption through specially crafted input strings. An attacker with database access could potentially achieve privilege escalation or cause service disruption, though exploit complexity is currently limited by restricted control over written data. No patch is currently available.

Technical ContextAI

Classified as CWE-122 (Heap-based Buffer Overflow). Affects Postgresql. Heap buffer overflow in PostgreSQL pg_trgm allows a database user to achieve unknown impacts via a crafted input string. The attacker has limited control over the byte patterns to be written, but we have not ruled out the viability of attacks that lead to privilege escalation. PostgreSQL 18.1 and 18.0 are affected.

RemediationAI

Monitor vendor advisories for a patch. Enable ASLR, DEP/NX, and stack canaries where possible. Restrict network access to the affected service where possible.
