-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - ------------------------------------------------------------------------- Debian Security Advisory DSA-3142-1 security@debian.org http://www.debian.org/security/ Florian Weimer January 27, 2015 http://www.debian.org/security/faq - ------------------------------------------------------------------------- Package : eglibc CVE ID : CVE-2012-6656 CVE-2014-6040 CVE-2014-7817 CVE-2015-0235 Several vulnerabilities have been fixed in eglibc, Debian's version of the GNU C library: CVE-2015-0235 Qualys discovered that the gethostbyname and gethostbyname2 functions were subject to a buffer overflow if provided with a crafted IP address argument. This could be used by an attacker to execute arbitrary code in processes which called the affected functions. The original glibc bug was reported by Peter Klotz. CVE-2014-7817 Tim Waugh of Red Hat discovered that the WRDE_NOCMD option of the wordexp function did not suppress command execution in all cases. This allows a context-dependent attacker to execute shell commands. CVE-2012-6656 CVE-2014-6040 The charset conversion code for certain IBM multi-byte code pages could perform an out-of-bounds array access, causing the process to crash. In some scenarios, this allows a remote attacker to cause a persistent denial of service. For the stable distribution (wheezy), these problems have been fixed in version 2.13-38+deb7u7. For the upcoming stable distribution (jessie) and the unstable distribution (sid), the CVE-2015-0235 issue has been fixed in version 2.18-1 of the glibc package. We recommend that you upgrade your eglibc packages.
