This issue was patched in RHSA-2016:0722.

NVD Description

Note: Versions mentioned in the description apply only to the upstream openssl-perl package and not the openssl-perl package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

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.
