CVE-2014-9556


Jakub Wilk originally reported to the Debian BTS a problem with
cabextract on a specially crafted cab file, causing cabextract to hang
forever. The problem is actually in the embedded copy of libmspack, see
[1]. Libmspack, a library to provide compression and decompression of
some file formats used by Microsoft, is used in many project (or
embedded there like also Clamav). This issue can cause a remotely
exploitable denial-of-service condition due to clamav thread hanging
forever while scanning the file. A patch is available at [2] for
libmspack.

Comment 2 Stanislav Brabec 2015-01-20 18:08:50 UTC 
Package fixed using the last Debian / clamav patch.

I sent a mail to the original upstream maintainer, as it seems to be active but not aware of this fix.

openSUSE:Factory: Created OBS request id 282135.
openSUSE:Maintenance (13.1, 13.2): Created OBS maintenance request id 282136
SUSE:Maintenance (SLE12): Created IBS maintenance request id 48764
SUSE:SLE-11:Update:Test: Created IBS request id 48766.

Note: SLE10 seems to be affected as well. Please let me know if update is wanted there as well.
Comment 4 Stanislav Brabec 2015-01-26 17:41:42 UTC 
libmspack upstream used a different patch than clamav:

This issue was fixed in revision 199: https://sourceforge.net/p/libmspack/code/199/

Replacing problematic patch from clamav upstream (which seems to cause hangs) by the patch from the mainline upstream.
Comment 12 Benjamin Brunner 2015-03-04 12:35:51 UTC 
Stanislav, your sr was declined from legal. Could you check and submit again please?
Comment 13 Stanislav Brabec 2015-03-04 14:30:37 UTC 
Looking at the later packages, I guess that I should change License to LGPL-2.1.
