Red Hat Security Advisory
Synopsis: Updated samba packages fix vulnerabilities
Advisory ID: RHSA-2004:467-01
Issue date: 2004-09-22
Updated on: 2004-09-22
Product: Red Hat Enterprise Linux
CVE Names: CAN-2004-0807 CAN-2004-0808
----------------------------------------------------------------------
1. Summary:
Updated samba packages that fix two denial of service vulnerabilities are now available.
2. Relevant releases/architectures:
Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Desktop version 3 - i386, x86_64
Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64
3. Problem description:
Samba provides file and printer sharing services to SMB/CIFS clients.
The Samba team has discovered a denial of service bug in the smbd daemon. A defect in smbd's ASN.1 parsing allows an attacker to send a specially crafted packet during the authentication request which will send the newly spawned smbd process into an infinite loop. Given enough of these packets, it is possible to exhaust the available memory on the server. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0807 to this issue.
Additionally the Samba team has also discovered a denial of service bug in the nmbd daemon. It is possible that an attacker could send a specially crafted UDP packet which could allow the attacker to anonymously crash nmbd. This issue only affects nmbd daemons which are configured to process domain logons. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0808 to this issue.
Users of Samba should upgrade to these updated packages, which contain an upgrade to Samba-3.0.7, which is not vulnerable to these issues.
4. Solution:
Before applying this update, make sure that all previously-released errata relevant to your system have been applied. Use Red Hat Network to download and update your packages. To launch the Red Hat Update Agent, use the following command:
up2date
