Multiple memory leaks in Samba before 3.0.6 allow attackers to cause a denial of service (memory consumption).

The unix_clean_name function in Samba 2.2.x through 2.2.11, and 3.0.x before 3.0.2a, trims certain directory names down to absolute paths, which could allow remote attackers to bypass the specified share restrictions and read, write, or list arbitrary files via "/.////" style sequences in pathnames.

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.

smbmnt in Samba 2.x and 3.x on Linux 2.6, when installed setuid, allows local users to gain root privileges by mounting a Samba share that contains a setuid root program, whose setuid attributes are not cleared when the share is mounted.

The mksmbpasswd shell script (mksmbpasswd.sh) in Samba 3.0.0 and 3.0.1, when creating an account but marking it as disabled, may overwrite the user password with an uninitialized buffer, which could enable the account with a more easily guessable password.
