Multiple vulnerabilities has been found and corrected in t1lib: A heap-based buffer overflow flaw was found in the way AFM font file parser, used for rendering of DVI files, in GNOME evince document viewer and other products, processed line tokens from the given input stream. A remote attacker could provide a DVI file, with embedded specially-crafted font file, and trick the local user to open it with an application using the AFM font parser, leading to that particular application crash or, potentially, arbitrary code execution with the privileges of the user running the application. Different vulnerability than CVE-2010-2642 . t1lib 5.1.2 and earlier reads from invalid memory locations, which allows remote attackers to cause a denial of service via a crafted Type 1 font in a PDF document, a different vulnerability than CVE-2011-0764 . Use-after-free vulnerability in t1lib 5.1.2 and earlier allows remote attackers to cause a denial of service via a PDF document containing a crafted Type 1 font that triggers an invalid memory write, a different vulnerability than CVE-2011-0764 . Off-by-one error in t1lib 5.1.2 and earlier allows remote attackers to cause a denial of service via a PDF document containing a crafted Type 1 font that triggers an invalid memory read, integer overflow, and invalid pointer dereference, a different vulnerability than CVE-2011-0764 . The updated packages have been patched to correct these issues.
