CVE-2023-45287

Before Go 1.20, the RSA based TLS key exchanges used the math/big library, which is not constant time. RSA blinding was applied to prevent timing attacks, but analysis shows this may not have been fully effective. In particular it appears as if the removal of PKCS1 padding may leak timing...

CVE-2023-45287

Summary of CVE-2023-45287 (Go): Before Go 1.20, RSA-based TLS key exchanges used math/big (not constant time). RSA blinding was applied but may not fully prevent timing leaks after removal of PKCS#1 padding, potentially enabling recovery of session key bits. Go 1.20+ switched crypto/tls to a full...

GO-2023-2375 Before Go 1.20, the RSA based key exchange methods in crypto/tls may exhibit a timing side channel

Before Go 1.20, the RSA based TLS key exchanges used the math/big library, which is not constant time. RSA blinding was applied to prevent timing attacks, but analysis shows this may not have been fully effective. In particular it appears as if the removal of PKCS1 padding may leak timing...

Google Go Security Vulnerability

Google Go is a static strongly typed, compiled, concatenated, and garbage-collected programming language from Google. A security vulnerability exists in Google Go versions prior to 1.20, which stems from the fact that deleting PKCS1 padding can lead to the disclosure of timing information, which...

PT-2023-29487

Name of the Vulnerable Software and Affected Versions Go versions prior to 1.20 Description The issue concerns the RSA-based TLS key exchanges in Go, which used the math/big library that is not constant time. Although RSA blinding was applied to prevent timing attacks, analysis suggests this may...
