Description

Michele Spagnuolo, of Google Security Team, and Miroslav Lichvar, of Red Hat, discovered two issues in flac, a library handling Free Lossless Audio Codec media: by providing a specially crafted FLAC file, an attacker could execute arbitrary code.

CVE-2014-8962

heap-based buffer overflow in stream_decoder.c, allowing remote attackers to execute arbitrary code via a specially crafted .flac file.

CVE-2014-9028

stack-based buffer overflow in stream_decoder.c, allowing remote attackers to execute arbitrary code via a specially crafted .flac file.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
