Last modified
CVE-2016-0797 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. Multiple integer overflows in OpenSSL 1.0.1 before 1.0.1s and 1.0.2 before 1.0.2g allow remote attackers to cause a denial of service (heap memory corruption or NULL pointer dereference) or possibly have unspecified other impact via a long digit string that is mishandled by the (1) BN_dec2bn or (2) BN_hex2bn function, related to crypto/bn/bn.h and crypto/bn/bn_print.c.. EPSS estimates a 27.02% chance of exploitation in the next 30 days.
