Description

Updated samba packages that fix buffer overflows, as well as other various bugs, are now available.

Samba provides file and printer sharing services to SMB/CIFS clients.

Evgeny Demidov discovered a flaw in the internal routine used by the Samba Web Administration Tool (SWAT) in Samba versions 3.0.2 through 3.0.4. When decoding base-64 data during HTTP basic authentication, an invalid base-64 character could cause a buffer overflow. If the SWAT administration service is enabled, this flaw could allow an attacker to execute arbitrary code. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-0600 to this issue.

Additionally, the Samba team discovered a buffer overflow in the code used to support the 'mangling method = hash' smb.conf option. Please be aware that the default setting for this parameter is 'mangling method = hash2' and therefore not vulnerable. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-0686 to this issue.

This release includes the updated upstream version 3.0.4 together with backported security patches to correct these issues as well as a number of post-3.0.4 bug fixes from the Samba subversion repository.

The most important bug fix allows Samba users to change their passwords if Microsoft patch KB 828741 (a critical update) had been applied.

All users of Samba should upgrade to these updated packages, which resolve these issues.
