Description Sune Kloppenborg Jeppesen (RETIRED) gentoo-dev 2005-08-24 22:02:05 UTC 
I think this was discovered by Marcus Meissner from SUSE and wrongly 
attributed by Secunia. 
 
Insecure temporary file handling in cvsbug program. 
 
Full details in URL.

CAN-2005-2693
"It is possible that a malicious user could leverage this issue to execute
arbitrary instructions as the user running cvsbug."

Time to vote, I tend to vote yes (more impact than just overwriting a file with
garbage, though cvsbug use is a little unlikely).
Comment 12 Tavis Ormandy (RETIRED) gentoo-dev 2005-08-30 09:21:41 UTC 
vote NO, difficult to exploit.

impossible to predict when someone is going to run cvsbug, and even if you could 
social engineer a situation when you knew the precise time that someone was 
going to execute it and convince them that they had found a bug that needed to 
be reported, you still need to win a race condition.
Comment 13 Sune Kloppenborg Jeppesen (RETIRED) gentoo-dev 2005-08-30 12:24:48 UTC 
I tend to vote NO.
Comment 14 Thierry Carrez (RETIRED) gentoo-dev 2005-08-31 00:30:04 UTC 
Reversing YES to NO, and closing.
