Mandriva Linux Security Advisory : python-pillow (MDVSA-2015:099)
Critical Nessus Plugin ID 82352
SynopsisThe remote Mandriva Linux host is missing one or more security updates.
DescriptionUpdated python-imaging packages fix security vulnerabilities :
Jakub Wilk discovered that temporary files were insecurely created (via mktemp()) in the IptcImagePlugin.py, Image.py, JpegImagePlugin.py, and EpsImagePlugin.py files of Python Imaging Library. A local attacker could use this flaw to perform a symbolic link attack to modify an arbitrary file accessible to the user running an application that uses the Python Imaging Library (CVE-2014-1932).
Jakub Wilk discovered that temporary files created in the JpegImagePlugin.py and EpsImagePlugin.py files of the Python Imaging Library were passed to an external process. These could be viewed on the command line, allowing an attacker to obtain the name and possibly perform symbolic link attacks, allowing them to modify an arbitrary file accessible to the user running an application that uses the Python Imaging Library (CVE-2014-1933).
The Python Imaging Library is vulnerable to a denial of service attack in the IcnsImagePlugin (CVE-2014-3589).
Python Image Library (PIL) 1.1.7 and earlier and Pillow 2.3 might allow remote attackers to execute arbitrary commands via shell metacharacters, due to an incomplete fix for CVE-2014-1932 (CVE-2014-3007).
Pillow before 2.7.0 and 2.6.2 allows remote attackers to cause a denial of service via a compressed text chunk in a PNG image that has a large size when it is decompressed (CVE-2014-9601).
SolutionUpdate the affected packages.
