ComputerWorld responded to my comment that Apple has patched Samba.
Here is their reply:
Although you are correct in pointing out that an Apple-specific Samba module was patched in the 2007-003 security update (and in the associated update to 10.4.9), none of the flaws patched by Samba in mid-May correspond to this single heap buffer overflow fixed in March by Apple.
Symantec, as the story mentions, has verified that the Samba vulnerabilities exist in a fully-patched 10.4.10 edition, in other words post 2007-003.
Also, credit to the 5/14 heap buffer overflow flaws in Samba (there are four all told) goes to Tipping Point’s Zero-Day Initiative bug bounty program, while the one in 2007-003 went to someone at New Zealand’s Massey University.
Check out the Samba release notes, specifically the reference to CVE-2007-2446, which covers the four buffer overflow bugs; and CVE-2007-2446.
In particular, the overflow vulnerabilty that RISE exploit is the one
detailed by ISS’ X-Force.
