Stack consumption vulnerability in the regcomp implementation in the GNU C
Library (aka glibc or libc6) through 2.11.3, and 2.12.x through 2.12.2,
allows context-dependent attackers to cause a denial of service (resource
exhaustion) via a regular expression containing adjacent repetition
operators, as demonstrated by a {10,}{10,}{10,}{10,} sequence in the
proftpd.gnu.c exploit for ProFTPD.
