The process_bin_delete function in memcached.c in memcached 1.4.4 and other versions before 1.4.17, when running in verbose mode, allows remote attackers to cause a denial of service (segmentation fault) via a request to delete a key, which does not account for the lack of a null terminator in the key and triggers a buffer over-read when printing to stderr.
Multiple integer signedness errors in the (1) process_bin_sasl_auth, (2) process_bin_complete_sasl_auth, (3) process_bin_update, and (4) process_bin_append_prepend functions in Memcached 1.4.5 and earlier allow remote attackers to cause a denial of service (crash) via a large body length value in a packet.
memcached.c in memcached before 1.4.3 allows remote attackers to cause a denial of service (daemon hang or crash) via a long line that triggers excessive memory allocation. NOTE: some of these details are obtained from third party information.
Multiple integer overflows in memcached 1.1.12 and 1.2.2 allow remote attackers to execute arbitrary code via vectors involving length attributes that trigger heap-based buffer overflows.
The process_stat function in Memcached 1.2.8 discloses memory-allocation statistics in response to a stats malloc command, which allows remote attackers to obtain potentially sensitive information by sending this command to the daemon's TCP port.
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.
