Mandriva Linux Security Advisory : libpng (MDVSA-2015:090)
Critical Nessus Plugin ID 82343
SynopsisThe remote Mandriva Linux host is missing one or more security updates.
DescriptionUpdated libpng package fixes security vulnerabilities :
The png_push_read_chunk function in pngpread.c in the progressive decoder in libpng 1.6.x through 1.6.9 allows remote attackers to cause a denial of service (infinite loop and CPU consumption) via an IDAT chunk with a length of zero (CVE-2014-0333).
libpng versions 1.6.9 through 1.6.15 have an integer-overflow vulnerability in png_combine_row() when decoding very wide interlaced images, which can allow an attacker to overwrite an arbitrary amount of memory with arbitrary (attacker-controlled) data (CVE-2014-9495).
SolutionUpdate the affected lib64png-devel and / or lib64png16_16 packages.
