Integer overflow in the Samba daemon (smbd) in Samba 2.x and 3.0.x through 3.0.9 allows remote authenticated users to cause a denial of service (application crash) and possibly execute arbitrary code via a Samba request with a large number of security descriptors that triggers a heap-based buffer overflow.
The process_logon_packet function in the nmbd server for Samba 3.0.6 and earlier, when domain logons are enabled, allows remote attackers to cause a denial of service via a SAM_UAS_CHANGE request with a length value that is larger than the number of structures that are provided.
Samba 3.0.6 and earlier allows remote attackers to cause a denial of service (infinite loop and memory exhaustion) via certain malformed requests that cause new processes to be spawned and enter an infinite loop.
Buffer overflow in the Samba Web Administration Tool (SWAT) in Samba 3.0.2 to 3.0.4 allows remote attackers to execute arbitrary code via an invalid base-64 character during HTTP basic authentication.
Buffer overflow in Samba 2.2.x to 2.2.9, and 3.0.0 to 3.0.4, when the "mangling method = hash" option is enabled in smb.conf, has unknown impact and attack vectors.
