OpenSSL ASN.1 code execution

openssl-asn1-code-execution (75099) The risk level is classified as HighHigh Risk

Description:

OpenSSL could allow a remote attacker to execute arbitrary code on the system, due to an incomplete fix for an error related to the truncation of integers when parsing encoded ASN.1 data. An attacker could exploit this vulnerability to corrupt memory and execute arbitrary code on the system.
