CESA-2005:357: gzip security update

Severity CVSS Published Added Modified

Description

An updated gzip package is now available. This update has been rated as having low security impact by the CentOS Security Response Team.

The gzip package contains the GNU gzip data compression program. A bug was found in the way zgrep processes file names. If a user can be tricked into running zgrep on a file with a carefully crafted file name, arbitrary commands could be executed as the user running zgrep. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-0758 to this issue. A bug was found in the way gunzip modifies permissions of files being decompressed. A local attacker with write permissions in the directory in which a victim is decompressing a file could remove the file being written and replace it with a hard link to a different file owned by the victim. gunzip then gives the linked file the permissions of the uncompressed file. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-0988 to this issue. A directory traversal bug was found in the way gunzip processes the -N flag. If a victim decompresses a file with the -N flag, gunzip fails to sanitize the path which could result in a file owned by the victim being overwritten. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-1228 to this issue. Users of gzip should upgrade to this updated package, which contains backported patches to correct these issues.
