Ronald Volgers discovered that memcached, a high-performance memory object caching system, is vulnerable to several heap-based buffer overflows due to integer conversions when parsing certain length attributes. An attacker can use this to execute arbitrary code on the system running memcached . For the oldstable distribution , this problem has been fixed in version 1.1.12-1+etch1. For the stable distribution , this problem has been fixed in version 1.2.2-1+lenny1. For the testing and unstable distribution , this problem will be fixed soon. We recommend that you upgrade your memcached packages.
