Samba AFS ACL mapping VFS plug-in contains a format string vulnerability. This vulnerability may allow a remote attacker to execute arbitrary code on a vulnerable system.
Samba AFS ACL mapping VFS plug-in fails to properly sanitize user-controlled file names that are used in a format specifier supplied to snprintf(). According to Samba Security Advisory CVE-2007-0454: Format string bug in afsacl.so VFS plug-in:
This security advisory only impacts Samba servers that share AFS file systems to CIFS clients and which have been explicitly instructed in smb.conf to load the afsacl.so VFS module.
If an attacker is able to write a file to a share that uses the afsacl.so library, that attacker may be able to execute arbitrary code.
