Three Questions for Billy Brumley on the OpenSSL Timing Attack

Timing attacks have been a problem for designers of cryptosystems–as well as for people implementing those systems–for a long time. They’ve plagued just about every popular system, and although practical attacks have been demonstrated many times, the problem and what can be done to defend against...

CVE-2010-3864

Multiple race conditions in ssl/t1lib.c in OpenSSL 0.9.8f through 0.9.8o, 1.0.0, and 1.0.0a, when multi-threading and internal caching are enabled on a TLS server, might allow remote attackers to execute arbitrary code via client data that triggers a heap-based buffer overflow, related to 1 the T...

CVE-2010-3864

CVE-2010-3864 involves a race condition in the OpenSSL TLS server extension parsing (ssl/t1_lib.c) when OpenSSL is used in multi‑threaded servers with internal caching, which can lead to a heap-based buffer overflow. Affected OpenSSL versions include 0.9.8f–0.9.8o and 1.0.0/1.0.0a. The issue can ...

Double free vulnerability in the ssl3getkeyexchange function in the OpenSSL client ssl/s3clnt.c in OpenSSL 1.0.0a, 0.9.8, 0.9.7, and possibly other versions, when using ECDH, allows context-dependent attackers to cause a denial of service crash and possibly execute arbitrary code via a crafted...

OpenSSL Incorrect checks for malformed signatures

OpenSSL 0.9.8i and earlier does not properly check the return value from the EVPVerifyFinal function, which allows remote attackers to bypass validation of the certificate chain via a malformed SSL/TLS signature for DSA and ECDSA keys...
