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 found in gzip, the GNU compression utilities. The Common Vulnerabilities and Exposures project identifies the following problems :

- CVE-2009-2624 Thiemo Nagel discovered a missing input sanitation flaw in the way gzip used to decompress data blocks for dynamic Huffman codes, which could lead to the execution of arbitrary code when trying to decompress a crafted archive. This issue is a reappearance of CVE-2006-4334 and only affects the lenny version.

- CVE-2010-0001 Aki Helin discovered an integer underflow when decompressing files that are compressed using the LZW algorithm. This could lead to the execution of arbitrary code when trying to decompress a crafted LZW compressed gzip archive.

Solution

Upgrade the gzip packages.

For the stable distribution (lenny), these problems have been fixed in version 1.3.12-6+lenny1.

For the oldstable distribution (etch), these problems have been fixed in version 1.3.5-15+etch1.
