Mandriva Linux Security Advisory : libpng (MDVSA-2015:090)

This script is Copyright (C) 2015 Tenable Network Security, Inc.


Synopsis :

The remote Mandriva Linux host is missing one or more security
updates.

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).
