Description OSIDB Bzimport 2026-06-25 13:15:00 UTC
Due to a improper validation of syntactic correctness of input bug, Squid is vulnerable to a out-of-bounds read attack against the FTP gateway.

This problem allows a trusted client to perform an out-of-bounds read from random unrelated transactions when accessing a misbehaving FTP server through Squid's gateway feature.
