Posted on: 02/08/2007 10:01 AM

New samba packages are available for Slackware 10.0, 10.1, 10.2, and 11.0 to fix a denial-of-service security issue.

More details about the issues fixed in Samba 3.0.24 may be found in the Common Vulnerabilities and Exposures (CVE) database:

http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-0452
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-0453
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-0454


Here are the details from the Slackware 11.0 ChangeLog:
+--------------------------+
patches/packages/samba-3.0.24-i486-1_slack11.0.tgz:
Upgraded to samba-3.0.24. From the WHATSNEW.txt file:
"Important issues addressed in 3.0.24 include:
o Fixes for the following security advisories:
- CVE-2007-0452 (Potential Denial of Service bug in smbd)
- CVE-2007-0453 (Buffer overrun in NSS host lookup Winbind
NSS library on Solaris)
- CVE-2007-0454 (Format string bug in afsacl.so VFS plugin)"
Samba is Slackware is vulnerable to the first issue, which can cause smbd
to enter into an infinite loop, disrupting Samba services. Linux is not
vulnerable to the second issue, and Slackware does not ship the afsacl.so
VFS plugin (but it's something to be aware of if you build Samba with
custom options).
