Package: libc6 Version: 2.6.1-2 Severity: important glibc's regular expression engine crashes with sig11 whenever trying to compile a regular expression with non-ASCII range expressions if LC_CTYPE is a UTF-8 locale but LC_COLLATE is set to C or POSIX. This is a common setup among users who want traditional codepoint-order sorting but need UTF-8 encoding.
$ LANG=en_US.UTF-8 LC_COLLATE=C grep '[Á-ä]' Segmentation fault The bug can cause crashes in any program using the system regex routines and could in principle be used for DoS attacks if a less-privileged user is able to provide regular expressions to a more-privileged process. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
