GPdf is a viewer for Portable Document Format files. Petr Gajdos and Christian Kornacker of SUSE reported a buffer overflow flaw in GPdf"s Type 1 font parser. A specially-crafted PDF file with an embedded Type 1 font could cause GPdf to crash or, possibly, execute arbitrary code when opened. Users are advised to upgrade to this updated package, which contains a backported patch to correct this issue.
