Description

Ettercap through 0.8.4.1 contains an out-of-bounds read and size_t underflow vulnerability in sslw_remove_sts() in src/ec_sslwrap.c, caused by a stale length and an unchecked memmem() result when stripping Strict-Transport-Security headers. A malicious HTTPS server whose response passes through Ettercap's SSL interception can trigger out-of-bounds reads and memory corruption in the Ettercap process, which normally runs as root.
