CVE-2012-2131
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,…
Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 16.8%, higher than 97% of all known CVEs. Patch or mitigate before the next change window.
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.
