Title:RHSA-2005:357: gzip security update (Low)
Description: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.
