-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ 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). _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-0333 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-9495 http://advisories.mageia.org/MGASA-2014-0131.html http://advisories.mageia.org/MGASA-2015-0008.html _______________________________________________________________________ Updated Packages: Mandriva Business Server 2/X86_64: 12c8bd2dd02e2521830355aa84176974 mbs2/x86_64/lib64png16_16-1.6.16-1.mbs2.x86_64.rpm 4a8f8b65c02ef36efd73e532b3019a1a mbs2/x86_64/lib64png-devel-1.6.16-1.mbs2.x86_64.rpm 7375c5ff0f64bba7ad6123bd92a1bbd1 mbs2/SRPMS/libpng-1.6.16-1.mbs2.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
