CVE-2012-2131 EXPLOIT

7.5
HIGH · CVSS 2.0 · EPSS 16.8% (pctl 97)

Patch early

A public exploit exists.

Description

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.
