CVE-2007-4903

Status: ModifiedHigh (7.5)—

Multiple buffer overflows in a certain ActiveX control in CryptoX.dll 2.0 and earlier in the Ultra Crypto Component allow remote attackers to execute arbitrary code via (1) a long string in the first argument to the AcquireContext method or (2) an unspecified vector to the DeleteContext method.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
