Details

A flaw was discovered in Samba's file opening code, which in certain
situations could lead to an endless loop, resulting in a denial of
service. (CVE-2007-0452)

A format string overflow was discovered in Samba's ACL handling on AFS
shares. Remote users with access to an AFS share could create crafted
filenames and execute arbitrary code with root privileges.
(CVE-2007-0454)

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 6.10
  • samba - 3.0.22-1ubuntu4.1
Ubuntu 6.06
  • samba - 3.0.22-1ubuntu3.2
Ubuntu 5.10
  • samba - 3.0.14a-6ubuntu1.2

In general, a standard system upgrade is sufficient to effect the
necessary changes.
