Two vulnerabilities have been identified in Samba, which could be exploited by attackers or malicious users to bypass security restrictions or compromise a vulnerable system.
The first issue is caused by a format string error in the smbclient utility when processing filenames supplied with a command (e.g. "put"), which could allow attackers to crash an affected client or execute arbitrary code by tricking a user or automated system into executing a command with a malicious filename argument.
The second vulnerability is caused by an uninitialized memory read when denying permissions while trying to modify an access control list (ACL), which could allow malicious users to modify the ACLs or writable files.
