GOST engine is a reference implementation of the Russian GOST crypto algorithms for OpenSSL. TLS clients using GOST engine when ciphersuite TLS_GOSTR341112_256_WITH_KUZNYECHIK_CTR_OMAC is agreed and the server uses 512 bit GOST secret keys are vulnerable to buffer overflow. GOST engine version 3.0.1 contains a patch for this issue. Disabling ciphersuite TLS_GOSTR341112_256_WITH_KUZNYECHIK_CTR_OMAC is a possible workaround.
AnalysisAI
GOST engine is a reference implementation of the Russian GOST crypto algorithms for OpenSSL. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. This Buffer Copy without Size Check vulnerability could allow attackers to overflow a buffer to corrupt adjacent memory.
Technical ContextAI
This vulnerability is classified as Buffer Copy without Size Check (CWE-120), which allows attackers to overflow a buffer to corrupt adjacent memory. GOST engine is a reference implementation of the Russian GOST crypto algorithms for OpenSSL. TLS clients using GOST engine when ciphersuite TLS_GOSTR341112_256_WITH_KUZNYECHIK_CTR_OMAC is agreed and the server uses 512 bit GOST secret keys are vulnerable to buffer overflow. GOST engine version 3.0.1 contains a patch for this issue. Disabling ciphersuite TLS_GOSTR341112_256_WITH_KUZNYECHIK_CTR_OMAC is a possible workaround. Affected products include: Gost Engine Project Gost Engine. Version information: version 3.0.1.
RemediationAI
A vendor patch is available. Apply the latest security update as soon as possible. Always validate buffer sizes before copy operations. Use bounded functions (strncpy, snprintf). Enable compiler protections.
