Description Vincent Danen 2012-09-13 22:08:45 UTC

An out-of-bounds read error was reported [1] in OpenSLP's SLPIntersectStringList() function (in common/sip_compare.c) when processing service requests.  This could be exploited to cause a crash via a specially-crafted request.  The report is against version 1.2.1, however other versions may be affected.

There is not yet any upstream patch or bug report.

Comment 9 Rex Dieter 2015-05-11 12:36:50 UTC

Found 2 patches produced in the wild that appear to be functionally the same,

https://bugs.debian.org/cgi-bin/bugreport.cgi?msg=27;filename=CVE-2012-4428.patch;att=1;bug=687597
( referenced from https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=687597 )

and 

http://cvsweb.netbsd.org/bsdweb.cgi/pkgsrc/net/openslp/patches/patch-CVE-2012-4428

I'm leaning toward using the debian variant.
