Debian Security Advisory

DSA-731-1 krb4 -- buffer overflows

Date Reported:

02 Jun 2005

Affected Packages:

krb4

Vulnerable:

Yes

Security database references:

In Mitre's CVE dictionary: CVE-2005-0468, CVE-2005-0469.
CERT's vulnerabilities, advisories and incident notes: VU#341908, VU#291924.

More information:

Several problems have been discovered in telnet clients that could be exploited by malicious daemons the client connects to. The Common Vulnerabilities and Exposures project identifies the following problems:

• CAN-2005-0468

  Gaël Delalleau discovered a buffer overflow in the env_opt_add() function that allow a remote attacker to execute arbitrary code.

• CAN-2005-0469

  Gaël Delalleau discovered a buffer overflow in the handling of the LINEMODE suboptions in telnet clients. This can lead to the execution of arbitrary code when connected to a malicious server.

For the stable distribution (woody) these problems have been fixed in version 1.1-8-2.4.

For the testing distribution (sarge) these problems have been fixed in version 1.2.2-11.2.

For the unstable distribution (sid) these problems have been fixed in version 1.2.2-11.2.

We recommend that you upgrade your krb4 packages.

Fixed in:

Debian GNU/Linux 3.0 (woody)
