CVE-2012-2131: OpenSSL

High severity, CVSS 7.5. EPSS: 16.8% chance of exploitation in the next 30 days.

Multiple integer signedness errors in crypto/buffer/buffer.c in OpenSSL 0.9.8v allow remote attackers to conduct buffer overflow attacks, and cause a denial of service (memory corruption) or possibly have unspecified other impact, via crafted DER data, as demonstrated by an X.509 certificate or an RSA public key. NOTE: this vulnerability exists because of an incomplete fix for CVE-2012-2110.

Affected products

• OpenSSL OpenSSL: version 0.9.8v only
