DATE CVE VULNERABILITY TITLE RISK
2016-03-03 CVE-2016-0799 Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in multiple products
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.
