From $URL : Description A vulnerability has been reported in GNU C Library, which can be exploited by malicious people to cause a DoS (Denial of Service). The vulnerability is caused due to an error within the "extend_buffers()" function (posix/regexec.c) when handling multibyte characters in regular expressions and can be exploited to cause a buffer overflow and crash the application. The vulnerability is reported in version 2.17. Other versions may also be affected. Solution No official solution is currently available. Provided and/or discovered by Paolo Bonzini in a bug report. Original Advisory http://sourceware.org/bugzilla/show_bug.cgi?id=15078 http://www.openwall.com/lists/oss-security/2013/01/30/1
CVE-2013-0242 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-0242): Buffer overflow in the extend_buffers function in the regular expression matcher (posix/regexec.c) in glibc, possibly 2.17 and earlier, allows context-dependent attackers to cause a denial of service (memory corruption and crash) via crafted multibyte characters.
Fix is in 2.18: http://sourceware.org/git/?p=glibc.git;a=blob_plain;f=NEWS;hb=HEAD
Can the fix be backported to stable glibc versions?
no plans to backport to glibc-2.17 or older
Maintainer(s), please drop the vulnerable version(s). Added to an existing GLSA Request.
