Publication date: 31 Dec 2014
Modification date: 31 Dec 2014
Type: security
Affected Mageia releases : 4
CVE: CVE-2014-8139 , CVE-2014-8140 , CVE-2014-8141

Description

Updated unzip package fix security vulnerabilities:

The unzip command line tool is affected by heap-based buffer overflows within
the CRC32 verification (CVE-2014-8139), the test_compr_eb() (CVE-2014-8140)
and the getZip64Data() (CVE-2014-8141) functions. The input errors may result
in in arbitrary code execution. A specially crafted zip file, passed to the
command unzip -t, can be used to trigger the vulnerability.

OOB access (both read and write) issues also exist in test_compr_eb()
that can result in application crash or other unspecified impact. A
specially crafted zip file, passed to the command unzip -t, can be used to
trigger the issues.
