Publication date: 31 Aug 2018
Type: security
Affected Mageia releases : 6
CVE: CVE-2018-1002209


Updated quazip packages fix security vulnerability:

A vulnerability has been found in the way developers have implemented the
archive extraction of files. An arbitrary file write vulnerability, that
can be achieved using a specially crafted zip archive (affects other
archives as well, bzip2, tar,xz, war, cpio, 7z), that holds path traversal
filenames. So when the filename gets concatenated to the target extraction
directory, the final path ends up outside of the target folder. Of course
if an executable or a configuration file is overwritten with a file
containing malicious code, the problem can turn into an arbitrary code
execution issue quite easily. This affects multiple libraries that lacks of
a high level APIs that provide the archive extraction functionality
