Synopsis


Samba contains multiple vulnerabilities potentially resulting in the execution of arbitrary code with root privileges.

Background


Samba is a suite of SMB and CIFS client/server programs for UNIX.

Affected packages



Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-fs/samba < 3.0.24-r2 >= 3.0.24-r2

Description


Samba contains a logical error in the smbd daemon when translating local SID to user names (CVE-2007-2444). Furthermore, Samba contains several bugs when parsing NDR encoded RPC parameters (CVE-2007-2446). Lastly, Samba fails to properly sanitize remote procedure input provided via Microsoft Remote Procedure Calls (CVE-2007-2447).

Impact


A remote attacker could exploit these vulnerabilities to gain root privileges via various vectors.

Workaround


There is no known workaround at this time.

Resolution


All Samba users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-fs/samba-3.0.24-r2"
