Package : eglibc Version : 2.11.3-4+deb6u11 CVE ID : CVE-2015-7547 Several vulnerabilities have been fixed in the Debian GNU C Library, eglibc: CVE-2015-7547 The Google Security Team and Red Hat discovered that the glibc host name resolver function, getaddrinfo, when processing AF_UNSPEC queries (for dual A/AAAA lookups), could mismange its internal buffers, leading to a stack-based buffer overflow and arbitrary code execution. This vulnerability affects most applications which perform host name resolution using getaddrinfo, including system services. The following fixed vulnerabilities currently lack CVE assignment: Andreas Schwab reported a memory leak (memory allocation without a matching deallocation) while processing certain DNS answers in getaddrinfo, related to the _nss_dns_gethostbyname4_r function. This vulnerability could lead to a denial of service. For Debian 6 "Squeeze", these issues have been fixed in eglibc version eglibc_2.11.3-4+deb6u11. In addition this version corrects the fix for CVE-2014-9761 in Squeeze, which have wrongly marked a few symbols as public instead of private. While it is only necessary to ensure that all processes are not using the old eglibc anymore, it is recommended to reboot the machines after applying the security upgrade. We recommend you to upgrade your eglibc packages.
