New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

SynopsisThe remote Debian host is missing a security-related update.
DescriptionTwo problems have been discovered in gzip, the GNU compression utility. The Common Vulnerabilities and Exposures project identifies the following problems.
- CAN-2005-0988 Imran Ghory discovered a race condition in the permissions setting code in gzip. When decompressing a file in a directory an attacker has access to, gunzip could be tricked to set the file permissions to a different file the user has permissions to.
Ulf Harnhammar discovered a path traversal vulnerability in gunzip. When gunzip is used with the -N option an attacker could use this vulnerability to create files in an arbitrary directory with the permissions of the user.
SolutionUpgrade the gzip package.
For the oldstable distribution (woody) these problems have been fixed in version 1.3.2-3woody5.
For the stable distribution (sarge) these problems have been fixed in version 1.3.5-10.
