Integer overflow in the read_nttrans_ea_list function in nttrans.c in smbd in Samba 3.x before 3.5.22, 3.6.x before 3.6.17, and 4.x before 4.0.8 allows remote attackers to cause a denial of service (memory consumption) via a malformed packet.
Multiple format string vulnerabilities in client/client.c in smbclient in Samba 3.2.0 through 3.2.12 might allow context-dependent attackers to execute arbitrary code via format string specifiers in a filename.
