Description

Several flaws were found in the way BIO_*printf functions were implemented in OpenSSL. Applications which passed large amounts of untrusted data through these functions could crash or potentially execute code with the permissions of the user running such an application.

Statement

The original issue fixed by OpenSSL upstream contains two distinct fixes. The first one is a format string flaw in the internal fmtstr functions, which may result in a OOB read flaw when printing very large string. This issue was assigned CVE-2016-0799

The second issue relates to the internal doapr_outch function of OpenSSL. It can result in an OOB write, or cause memory leaks. This issue has been assigned CVE-2016-2842 by MITRE as is now tracked as https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2016-2842
