Dia multiple buffer overflows

infamous41md discovered three buffer overflows in Dia's xfig importer.
The issues are caused by unchecked input from the xfig file.

The patch can be found here:

Comment 2 Pekka Savola 2006-05-07 00:56:23 EDT
Two questions:

 - in RHL9, the patch appears to be commented out?  Does this package require to
be re-spun, or can this be fixed at build time?
 - Are we affected by CVE-2005-2966? RHEL hasn't patched it at least and
bugzilla search is not working properly so I can't check whether there is bz#
for it..

Other than that, looks good.
Comment 3 Marc Deslauriers 2006-05-07 10:13:22 EDT
Argh...thanks for noticing the commented out patch in rh9...

You're right. Looks like we're affected by CVE-2005-2966. I can't find a
bugzilla entry for it for RHEL either, but Debian has a patch we can use.

I'll respin these.

Looks like there are more potential issues with dia than the CVE-2006-1550 issue
addressed by this bugzilla ticket.  Hans de Goede of the Fedora Security project
has fixed two format string vulnerabilities for the FE5 version of dia for two
new CVE's:

 *  CVE-2006-2480 - "Format string vulnerability in Dia 0.94 allows
    user-complicit attackers to cause a denial of service (crash) and
    possibly execute arbitrary code by triggering errors or warnings,
    as demonstrated via format string specifiers in a .bmp filename. 
    NOTE: the original exploit was demonstrated through a command line
    argument, but there are other mechanisms inputs that are automatically
    process by Dia, such as a crafted .dia file."  (See Bug #192535 for FE5;
    and Bug #192538 & Bug #192699 for FC4).

*   CVE-2006-2453 - Additional dia format string flaws ("** RESERVED **
    This candidate has been reserved ... yada yada yada").  (See Bug #192830 
    for FE5, and Bug #192699 for FC4).

I haven't checked the code yet, but I imagine if there are string format
vulnerabilities in dia, that they've been there for a long time, and therefore
fixes for CVE-2006-2453 and CVE-2006-2480 could be backported...

Fedora Legacy project has ended.  These will not be fixed by Fedora Legacy.
