Description

This security bulletin contains information about 4 secuirty vulnerabilities.


1) Input validation error (CVE-ID: CVE-2010-2640)

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

Array index error in the PK 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.


2) Input validation error (CVE-ID: CVE-2010-2641)

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

Array index error in the 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.


3) Heap-based buffer overflow (CVE-ID: CVE-2010-2642)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in Heap-based buffer overflow in the AFM font parser in the dvi-backend component in Evince 2.32 and earlier, teTeX 3.0, t1lib 5.1.2, and possibly other products. A remote attacker can use a crafted font in conjunction with a DVI file that is processed by the thumbnailer. to trigger heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


4) Input validation error (CVE-ID: CVE-2010-2643)

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

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.
