| Name | CVE-2010-4052 |
| Description | 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. |

Deficiency in the regexp engine of glibc, while there implementations which
process such expressions more efficiently, imposing a limit lies within
the application accepting it from user input
