CVE request:

http://seclists.org/oss-sec/2016/q3/288

Double free vulnerability in the DefaultICCintents function in cmscnvrt.c in liblcms2 in Little CMS 2.x before 2.6 allows remote attackers to execute arbitrary code via a malformed ICC profile that triggers an error in the default intent handler.

Little CMS (lcms2) before 2.5, as used in OpenJDK 7 and possibly other products, allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via vectors related to (1) cmsStageAllocLabV2ToV4curves, (2) cmsPipelineDup, (3) cmsAllocProfileSequenceDescription, (4) CurvesAlloc, and (5) cmsnamed.
