-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDVSA-2015:065 http://www.mandriva.com/en/support/security/ _______________________________________________________________________ Package : cpio Date : March 27, 2015 Affected: Business Server 2.0 _______________________________________________________________________ Problem Description: Updated cpio package fixes security vulnerabilities: Heap-based buffer overflow in the process_copy_in function in GNU Cpio 2.11 allows remote attackers to cause a denial of service via a large block value in a cpio archive (CVE-2014-9112). Additionally, a null pointer dereference in the copyin_link function which could cause a denial of service has also been fixed. In GNU Cpio 2.11, the --no-absolute-filenames option limits extracting contents of an archive to be strictly inside a current directory. However, it can be bypassed with symlinks. While extracting an archive, it will extract symlinks and then follow them if they are referenced in further entries. This can be exploited by a rogue archive to write files outside the current directory (CVE-2015-1197). _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-9112 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2015-1197 http://advisories.mageia.org/MGASA-2014-0528.html http://advisories.mageia.org/MGASA-2015-0080.html _______________________________________________________________________ Updated Packages: Mandriva Business Server 2/X86_64: c6a401b3926824f66db80f0f9549cd5f mbs2/x86_64/cpio-2.11-7.1.mbs2.x86_64.rpm c34268ad5a7305e1e1bbc0a8b7d12462 mbs2/SRPMS/cpio-2.11-7.1.mbs2.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
