gzip: Multiple vulnerabilities

Background gzip GNU zip is a popular compression program. The included zgrep utility allows you to grep gzipped files in place. Description The gzip and gunzip programs are vulnerable to a race condition when setting file permissions CAN-2005-0988, as well as improper handling of filename...

USN-116-1: gzip vulnerabilities

Imran Ghory discovered a race condition in the file permission restore code of gzip and gunzip. While a user was compressing or decompressing a file, a local attacker with write permissions in the directory of that file could replace the target file with a hard link. This would cause gzip to...

CVE-2005-1228

Directory traversal vulnerability in gunzip -N in gzip 1.2.4 through 1.3.5 allows remote attackers to write to arbitrary directories via a .. dot dot in the original filename within a compressed file...

DEBIAN-CVE-2005-0988

Race condition in gzip 1.2.4, 1.3.3, and earlier, when decompressing a gzipped file, allows local users to modify permissions of arbitrary files via a hard link attack on a file while it is being decompressed, whose permissions are changed by gzip after the decompression is complete...

gzip -- directory traversal and permission race vulnerabilities

Problem Description Two problems related to extraction of files exist in gzip: The first problem is that gzip does not properly sanitize filenames containing "/" when uncompressing files using the -N command line option. The second problem is that gzip does not set permissions on newly extracted...

CVE-2005-0988

CVE-2005-0988 describes a race condition in gzip prior to 1.3.5 that affects permission handling during decompression. Specifically, when decompressing a file, a local attacker could exploit a hard-link or timing issue to change the permissions of an arbitrary file (or overwrite it) in the target...

CVE-2004-0970

The 1 gzexe, 2 zdiff, and 3 znew scripts in the gzip package, as used by other packages such as ncompress, allows local users to overwrite files via a symlink attack on temporary files. NOTE: the znew vulnerability may overlap CVE-2003-0367...
