========================================================================== Ubuntu Security Notice USN-3398-1 August 21, 2017 graphite2 vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 17.04 - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS Summary: graphite2 could be made to crash or run programs if it opened a specially crafted font. Software Description: - graphite2: Font rendering engine for Complex Scripts Details: Holger Fuhrmannek and Tyson Smith discovered that graphite2 incorrectly handled certain malformed fonts. If a user or automated system were tricked into opening a specially-crafted font file, a remote attacker could use this issue to cause graphite2 to crash, resulting in a denial of service, or possibly execute arbitrary code. Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 17.04: libgraphite2-3 1.3.10-0ubuntu0.17.04.1 Ubuntu 16.04 LTS: libgraphite2-3 1.3.10-0ubuntu0.16.04.1 Ubuntu 14.04 LTS: libgraphite2-3 1.3.10-0ubuntu0.14.04.1 This update uses a new upstream release, which includes additional bug fixes. After a standard system update you need to restart applications using graphite2, such as LibreOffice, to make all the necessary changes.
