Bug 61457 – net-im/gaim Security vulnerabilities in current Gaim

• Product: Gentoo Security
• Status: RESOLVED FIXED

[Description Curtis Magyar 2004-08-23 18:29:12 UTC]

Three potential vulnerabilites have been discovered in Gaim 0.81. They are all fixed for Gaim 0.82 and a patch from 0.81 is available here.
MSN Protocol Plugin

In two places in the MSN protocol plugins (object.c and slp.c), strncpy was used incorrectly; the size of the array was not checked before copying to it. Both bugs affect MSN's MSNSLP protocol, which is peer-to-peer, so this could potentially be easy to exploit.
Drag-and-Drop Smiley Themes

To install a new smiley theme, a user can drag a tarball from a graphical file manager, or a hypertext link to one from a web browser. When a tarball is dragged, Gaim executes a shell command to untar it. However, it does not escape the filename before sending it to the shell. Thus, a specially crafted filename could execute arbitrary commands if the user could be convinced to drag a file into the smiley theme selector.

gaim-bugs please bump to 0.82

[Comment 2 Curtis Magyar 2004-08-23 21:13:00 UTC]

0.82 isn't out until Thursday, and like last time they aren't immediately releasing a minor version to fix the vulnerability.  I wasn't sure if the patch had been applied or not, and didn't see a notice about it so I filed this.  Please close it if the patch is already included.

[Comment 3 Don Seiler (RETIRED) 2004-08-24 06:27:48 UTC]

Patches for items listed on gaim webpage are already patched.  Two of them were patched in 0.81-r1 and the third is patched in 0.81-r3.

There are other known vulnerabilities and I am working closely with gaim and other distro managers on it.  All are already patched in CVS and I will working to extract those diffs, but regardless I am going to recommend putting 0.82 into stable ASAP when it comes out.

[Comment 4 Don Seiler (RETIRED) 2004-08-24 06:53:01 UTC]

Gaim has sent a nice uberpatch for all known vulnerabilities.  Just committed in the form of gaim-0.81-r5.  I'd suggest marking stable ASAP.  I can do x86.

[Comment 5 Don Seiler (RETIRED) 2004-08-24 06:59:52 UTC]

Stable in x86.  Other arches can you please mark gaim-0.81-r5 stable ASAP for security purposes.  Will also involve marking gaim-encryption-2.29 stable, which is not a problem.

[Comment 6 Gustavo Zacarias (RETIRED) 2004-08-24 08:13:04 UTC]

Sparc stable.

[Comment 7 Pieter Van den Abeele (RETIRED) 2004-08-24 10:45:52 UTC]
