Debian Security Advisory DSA 345-1                     security@debian.org

Package        : xbl 
Vulnerability  : buffer overflow 
Problem-Type   : local 
Debian-specific: no 
CVE Ids        : CAN-2003-0535 
 
Another buffer overflow was discovered in xbl, distinct from the one 
addressed in DSA-327 (CAN-2003-0451), involving the -display command 
line option.  This vulnerability could be exploited by a local 
attacker to gain gid 'games'.
Comment 1 Mr. Bones. (RETIRED) gentoo-dev 2003-08-17 04:25:05 UTC
Unless I'm missing something, I'm pretty sure this isn't an issue on Gentoo
since xbl isn't installed setgid.

-rwxr-x---    1 games    games      163396 Aug 17 04:21 /usr/games/bin/xbl

I guess if you're running Debian you should be concerned. ;-)
Comment 2 SpanKY gentoo-dev 2003-08-17 11:32:08 UTC
who knows maybe you can get uid games ... thats a 'semi' issue 
Comment 3 Mr. Bones. (RETIRED) gentoo-dev 2003-08-17 14:32:31 UTC
How would that be possible?  The executable isn't setuid or setgid.  Even if
there is an exploitable bug in xbl, the program isn't run with anything other
than the user's permissions and group.
Comment 4 SpanKY gentoo-dev 2003-08-17 16:50:33 UTC
err you're right ... 
 
aliz, you can send out a GLSA but be sure to note that standard gentoo installs 
arent affected ... the only people who are affected are those who setgid on the 
binary themselves 
Comment 5 solar (RETIRED) gentoo-dev 2003-09-22 01:12:02 UTC
GLSA deadlock?
Comment 6 Chris Gianelloni (RETIRED) gentoo-dev 2003-10-07 03:48:44 UTC
resolved?
Comment 7 solar (RETIRED) gentoo-dev 2003-12-10 14:52:24 UTC
Re: comment #3 your right, so changing resolution to INVALID
