CVE-2010-4051

Priority
Description
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 (application crash) via a regular
expression containing adjacent bounded repetitions that bypass the intended
RE_DUP_MAX limitation, as demonstrated by a {10,}{10,}{10,}{10,}{10,}
sequence in the proftpd.gnu.c exploit for ProFTPD, related to a "RE_DUP_MAX
overflow."
Notes
 mdeslaur> debatable wheither this is a security issue or not.
 mdeslaur> application should impose limits and filtering. Ignoring.
