| Name | CVE-2009-1255 |
| Description | The process_stat function in (1) Memcached before 1.2.8 and (2) MemcacheDB 1.2.0 discloses (a) the contents of /proc/self/maps in response to a stats maps command and (b) memory-allocation statistics in response to a stats malloc command, which allows remote attackers to obtain sensitive information such as the locations of memory regions, and defeat ASLR protection, by sending a command to the daemon's TCP port. |

Notes
[etch] - memcached <no-dsa> (Minor issue)
[lenny] - memcached <no-dsa> (Minor issue)
[squeeze] - memcached <no-dsa> (Minor issue)
[squeeze] - memcachedb <no-dsa> (Minor issue)
why are weaknesses in security hardening features like ASLR considered minor?
even though this is not directly a vulnerability itself, part of this application's armor is now missing; making it easier for unknown vulnerabilities to be effective.
