CVE-2016-0799  (opens in a new tab)
CWE-119  (opens in a new tab)

How to fix?

Upgrade openssl to version 1.0.1s, 1.0.2g or higher.

Overview

Affected versions of this package are vulnerable to Out-of-Bounds. The fmtstr function in crypto/bio/b_print.c in OpenSSL 1.0.1 before 1.0.1s and 1.0.2 before 1.0.2g improperly calculates string lengths, which allows remote attackers to cause a denial of service (overflow and out-of-bounds read) or possibly have unspecified other impact via a long string, as demonstrated by a large amount of ASN.1 data, a different vulnerability than CVE-2016-2842.
