firefox vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 11.10 - Ubuntu 11.04 - Ubuntu 10.10 - Ubuntu 10.04 LTS
Summary:
Firefox could be made to crash or run programs as your login if it opened a specially crafted file.
Software Description: - firefox: Mozilla Open Source web browser
Details:
USN-1367-1 fixed vulnerabilities in libpng. This provides the corresponding update for Firefox.
Original advisory details: Jueri Aedla discovered that libpng did not properly verify the size used when allocating memory during chunk decompression. If a user or automated system using libpng were tricked into opening a specially crafted image, an attacker could exploit this to cause a denial of service or execute code with the privileges of the user invoking the program. (CVE-2011-3026)
