Name of the Vulnerable Software and Affected Versions 8cc (affected versions not specified)
Description An Out-of-Bounds Read occurs due to improper handling of #line directives and GNU linemarkers. The compiler accepts attacker-controlled filename and line number metadata and uses it without validation when accessing source line arrays. By supplying invalid or oversized line numbers, an attacker can trigger out-of-bounds memory access and a crash.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
