Mandriva Linux Security Advisory 2015-090 - 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 via an IDAT chunk with a length of zero. 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 data.

Mandriva Linux Security Advisory MDVSA-2015:090
http://www.mandriva.com/en/support/security/
_______________________________________________________________________

Package : libpng
Date : March 28, 2015
Affected: Business Server 2.0
_______________________________________________________________________

Problem Description:

Updated 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).
