DSA-2061-1 samba -- memory corruption

Date Reported:
16 Jun 2010
Affected Packages:
samba
Vulnerable:
Yes
Security database references:
In Mitre's CVE dictionary: CVE-2010-2063.
More information:

Jun Mao discovered that Samba, an implementation of the SMB/CIFS protocol for Unix systems, is not properly handling certain offset values when processing chained SMB1 packets. This enables an unauthenticated attacker to write to an arbitrary memory location resulting in the possibility to execute arbitrary code with root privileges or to perform denial of service attacks by crashing the samba daemon.

For the stable distribution (lenny), this problem has been fixed in version 3.2.5-4lenny12.

This problem does not affect the versions in the testing (squeeze) and unstable (sid) distribution.

We recommend that you upgrade your samba packages.

DSA-2062-1 sudo -- missing input sanitization

Date Reported:
17 Jun 2010
Affected Packages:
sudo
Vulnerable:
Yes
Security database references:
In the Debian bugtracking system: Bug 585394.
In Mitre's CVE dictionary: CVE-2010-1646.
More information:
Anders Kaseorg and Evan Broder discovered a vulnerability in sudo, a program designed to allow a sysadmin to give limited root privileges to users, that allows a user with sudo permissions on certain programs to use those programs with an untrusted value of PATH. This could possibly lead to certain intended restrictions being bypassed, such as the secure_path setting.

For the stable distribution (lenny), this problem has been fixed in version 1.6.9p17-3

For the unstable distribution (sid), this problem has been fixed in version 1.7.2p7-1, and will migrate to the testing distribution (squeeze) shortly.

We recommend that you upgrade your sudo package.

For the stable distribution (lenny), this problem has been fixed in version 0.9.18-2+lenny1

For the unstable distribution (sid), this problem has been fixed in version 0.9.23-1, and will migrate to the testing distribution (squeeze) shortly.

We recommend that you upgrade your pmount package.
