libpam-smb - buffer overflow



Debian Security Advisory

DSA-374-1 libpam-smb -- buffer overflow

Date Reported:
26 Aug 2003
Affected Packages:
libpam-smb
Vulnerable:
Yes
Security database references:
In Mitre's CVE dictionary: CAN-2003-0686.
More information:

libpam-smb is a PAM authentication module which makes it possible to authenticate users against a password database managed by Samba or a Microsoft Windows server. If a long password is supplied, this can cause a buffer overflow which could be exploited to execute arbitrary code with the privileges of the process which invokes PAM services.

For the stable distribution (woody) this problem has been fixed in version 1.1.6-1.1woody1.

The unstable distribution (sid) does not contain a libpam-smb package.

We recommend that you update your libpam-smb package.

Fixed in:

Debian GNU/Linux 3.0 (woody)
