Comment 3 Alexander Bezrukov 2010-06-10 02:33:04 UTC
This is infamous issue with open() call with gcc-4.4 which catches it.
The source code contains a BUG. When open(2) is called with the O_CREAT flag, the creation mode MUST be passed. Otherwise, a garbage is used as a creation mode which is potentially an exploitable SECURITY issue.

I will prepare a patch which fixes this problem.

A proposed ebuild (need not be -r1)

Only added one epatch line.

adding 1.4.0-r1 and this patch would be pointless, since this is already fixed in
Comment 7 Samuli Suominen gentoo-dev 2010-06-10 09:33:23 UTC
closing as invalid because it's already been fixed.
