Jon Larimer from IBM X-Force Advanced Research discovered multiple vulnerabilities in the DVI backend of the Evince document viewer :

  - CVE-2010-2640     Insufficient array bounds checks in the PK fonts parser     could lead to function pointer overwrite, causing     arbitrary code execution.

  - CVE-2010-2641     Insufficient array bounds checks in the VF fonts parser     could lead to function pointer overwrite, causing     arbitrary code execution.

  - CVE-2010-2642     Insufficient bounds checks in the AFM fonts parser when     writing data to a memory buffer allocated on heap could     lead to arbitrary memory overwrite and arbitrary code     execution.

  - CVE-2010-2643     Insufficient check on an integer used as a size for     memory allocation can lead to arbitrary write outside     the allocated range and cause arbitrary code execution.

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-2010-2640, CVE-2010-2641)

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-2010-2642)

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.
(CVE-2010-2643)

Note: The above issues are not exploitable unless an attacker can trick the user into installing a malicious font file.

Multiple font parser vulnerabilities in the DVI backend of evince have been fixed. CVE-2010-2640 - CVE-2010-2643 have been assigned to these issues.

The remote host is affected by the vulnerability described in GLSA-201111-10 (Evince: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Evince. Please review       the CVE identifiers referenced below for details.
  Impact :

    A remote attacker could entice a user to load a DVI file with a       specially crafted font, resulting in the execution of arbitrary code with       the privileges of the user running the application or a Denial of       Service.
  Workaround :

    There is no known workaround at this time.

Updated evince packages that fix multiple security issues are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

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.
(CVE-2010-2643)

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.

Multiple vulnerabilities has been found and corrected in evince :

Array index error in the PK and VF font parser in the dvi-backend component in Evince 2.32 and earlier allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted font in conjunction with a DVI file that is processed by the thumbnailer (CVE-2010-2640, CVE-2010-2641).

Heap-based buffer overflow in the AFM font parser in the dvi-backend component in Evince 2.32 and earlier allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted font in conjunction with a DVI file that is processed by the thumbnailer (CVE-2010-2642).

Integer overflow in the TFM font parser in the dvi-backend component in Evince 2.32 and earlier allows remote attackers to execute arbitrary code via a crafted font in conjunction with a DVI file that is processed by the thumbnailer (CVE-2010-2643).

The updated packages have been patched to correct these issues.

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.

Jon Larimer discovered that Evince's font parsers incorrectly handled certain buffer lengths when rendering a DVI file. By tricking a user into opening or previewing a DVI file that uses a specially crafted font file, an attacker could crash evince or execute arbitrary code with the user's privileges.

In the default installation of Ubuntu 9.10 and later, attackers would be isolated by the Evince AppArmor profile.
