Tracker summary

CVE-2016-7053 medium priority: Ubuntu including 3 source packages (openssl, openssl098, openssl1.0), 15 status rows across 5 suites (precise, trusty, upstream, xenial, yakkety): DNE 7, not-affected 5, needs-triage 3.

Description:

In OpenSSL 1.1.0 before 1.1.0c, applications parsing invalid CMS structures can crash with a NULL pointer dereference. This is caused by a bug in the handling of the ASN.1 CHOICE type in OpenSSL 1.1.0 which can result in a NULL value being passed to the structure callback if an attempt is made to free certain invalid encodings. Only CHOICE structures using a callback which do not handle NULL value are affected.
