JLSEC-2026-48

Client use of server error message in PostgreSQL allows a server not trusted under current SSL or GSS settings to furnish arbitrary non-NUL bytes to the libpq application. For example, a man-in-the-middle attacker could send a long error message that a human or screen-scraper user of psql mistake...

FreeBSD Buffer Overflow Vulnerability (CNVD-2026-16037)

FreeBSD is a set of Unix-like operating systems from the FreeBSD Foundation. A buffer overflow vulnerability exists in FreeBSD. The vulnerability stems from the routine to verify packet signatures in the RPCSECGSS implementation of kgssapi.ko not properly verifying data boundaries, which can be...

CVE-2026-4747

Each RPCSECGSS data packet is validated by a routine which checks a signature in the packet. This routine copies a portion of the packet into a stack buffer, but fails to ensure that the buffer is sufficiently large, and a malicious client can trigger a stack overflow. Notably, this does not...
