Evince is a document viewer.
- CVE-2010-2640, CVE-2010-2641
- An array index error was found in the DeVice Independent (DVI) renderer's PK and VF font file parsers. A DVI file that references a specially-crafted font file could, when opened, cause Evince to crash or, potentially, execute arbitrary code with the privileges of the user running Evince.
- CVE-2010-2642
- A heap-based buffer overflow flaw was found in the DVI renderer's AFM font file parser. A DVI file that references a specially-crafted font file could, when opened, cause Evince to crash or, potentially, execute arbitrary code with the privileges of the user running Evince.
- CVE-2010-2643
- An integer overflow flaw was found in the DVI renderer's TFM font file parser. A DVI file that references a specially-crafted font file could, when opened, cause Evince to crash or, potentially, execute arbitrary code with the privileges of the user running Evince.
Note: The above issues are not exploitable unless an attacker can trick the user into installing a malicious font file.
Red Hat would like to thank the Evince development team for reporting these issues. Upstream acknowledges Jon Larimer of IBM X-Force as the original reporter of these issues.
Users are advised to upgrade to these updated packages, which contain a backported patch to correct these issues.
