SKCertService 2.5.5 and earlier contains a vulnerability that could allow remote attacker to execute arbitrary code. This vulnerability exists due to the way .dll files are loaded by SKCertService. It allows an attacker to load a .dll of the attacker's choosing that could execute arbitrary code without the user's knowledge.

Multiple stack-based buffer overflows in the SignKorea SKCrypAX ActiveX control module 5.4.1.2 allow remote attackers to execute arbitrary code via a long string in unspecified arguments to the (1) DownloadCert, (2) DecryptFileByKey, and (3) EncryptFileByKey functions, a different module and vectors than CVE-2007-1722. NOTE: the provenance of this information is unknown; the details are obtained solely from third party information.

Buffer overflow in the DownloadCertificateExt function in SignKorea SKCommAX ActiveX control module 7.2.0.2 and 3280 6.6.0.1 allows remote attackers to execute arbitrary code via a long pszUserID argument.
