Vulnerability Note VU#544656

libFLAC contains multiple vulnerabilities

Overview

libFLAC contains multiple vulnerabilities, which may allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.

I. Description

FLAC (Free Lossless Audio Codec) is a lossless audio format. libFLAC is a library that can process FLAC files. libFLAC contains multiple vulnerabilities, including:
  • Metadata Block Size Heap Overflow
  • VORBIS Comment String Size Field Heap Overflow
  • VORBIS Comment String Size Length Stack Overflow
  • Picture MIME-Type Size Heap Overflow
  • Picture MIME-Type Size Stack Overflow
  • Picture Dimension Size Heap Overflow
  • Picture Description Size Heap Overflow
  • Picture Description Length Stack Overflow
  • Picture Data Length Heap Overflow
  • Picture URL Stack Overflow
  • Malformed Image/File Download Vulnerability
  • Padding Length Heap Overflow
  • Seektable Out-Of-Scope Double Free Condition
  • Malformed Seektable Double Free Condition
Please see eEye advisory AD20071115 for more details.

II. Impact

By convincing a user to open a specially crafted FLAC file, a remote, unauthenticated attacker may be able to execute arbitrary code or cause a denial-of-service condition on a vulnerable system.

III. Solution

Apply an update

These issues are addressed in version 1.2.1 of the FLAC library. Please see the Systems Affected section for fix availability for specific products.
