high Nessus Plugin ID 25151
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Debian host is missing a security-related update.

Description

Several vulnerabilities have been discovered in the QEMU processor emulator, which may lead to the execution of arbitrary code or denial of service. The Common Vulnerabilities and Exposures project identifies the following problems :

- CVE-2007-1320 Tavis Ormandy discovered that a memory management routine of the Cirrus video driver performs insufficient bounds checking, which might allow the execution of arbitrary code through a heap overflow.

- CVE-2007-1321 Tavis Ormandy discovered that the NE2000 network driver and the socket code perform insufficient input validation, which might allow the execution of arbitrary code through a heap overflow.

- CVE-2007-1322 Tavis Ormandy discovered that the 'icebp' instruction can be abused to terminate the emulation, resulting in denial of service.

- CVE-2007-1323 Tavis Ormandy discovered that the NE2000 network driver and the socket code perform insufficient input validation, which might allow the execution of arbitrary code through a heap overflow.

- CVE-2007-1366 Tavis Ormandy discovered that the 'aam' instruction can be abused to crash qemu through a division by zero, resulting in denial of service.

Solution

Upgrade the qemu packages.

For the oldstable distribution (sarge) these problems have been fixed in version 0.6.1+20050407-1sarge1.

For the stable distribution (etch) these problems have been fixed in version 0.8.2-4etch1.
