Title

Уязвимость реализации алгоритма шифрования по ГОСТ 34.12 библиотеки CTR_OMAC, применяемой при реализации протокола OpenSSL, позволяющая нарушителю вызвать переполнение буфера при условии, что сервер использует 512-битные секретные ключи

Description

Уязвимость реализации алгоритма шифрования по ГОСТ 34.12 библиотеки CTR_OMAC, применяемой при реализации протокола OpenSSL, связана с ошибками обработки ключа шифрования BLOB-объекта (большого бинарного объекта) в переменной TLS_GOSTR341112_256_WITH_KUZNYECHIK_CTR_OMAC. Эксплуатация уязвимости может позволить нарушителю, действующему удаленно, вызвать переполнение буфера при условии, что сервер использует 512-битные секретные ключи

CVE-2022-29242 (GCVE-0-2022-29242)

Vulnerability from cvelistv5 – Published: 2022-05-24 14:55 – Updated: 2025-04-23 18:22

Title

Buffer Overflow on creating key transport blob in GOST Engine

Summary

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.

Severity
