As far as I know, none have been assigned so far.I think you missed this: http://www.openwall.com/lists/oss-security/2014/05/08/1 in which CVE-2014-3215 was assigned.I did. Thanks.Does your CVE request still stand, or are you satisfied with this one CVE id for the interaction (not for a particular component)?
I think that one CVE is for the interaction is fine.
FWIW, it appears that common exim configurations are vulnerable, so this might be worse than just an exposure.Please try to demo this. Thanks!
I can give it a shot, but there's no ETA, since I have no clue how to use exim. I just looked at the source, and it appears to use setuid (as opposed to setresuid) to drop privileges, and it will dlopen user-requested libraries. I think that the other issues in the original post may be CVE-worthy despite their low impact -- they can, at best, cause sandbox protection to be less effective than intended. --Andy
