    CVE-2009-1255

    Published: 30 Apr 2009Last Modified: 10 Apr 2026

    Summary:

    Details: 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.
