The archive/zip package now rejects files containing these errors.

CVE-2023-45285 [HIGH] CVE-2023-45285: Using go get to fetch a module with the ".git" suffix may unexpectedly fallback to the insecure "git Using go get to fetch a module with the ".git" suffix may unexpectedly fallback to the insecure "git://" protocol if the module is unavailable via the secure "https://" and "git+ssh://" protocols, even if GOINSECURE is not set for said module. This only affects users who are not using the module proxy and are fetching modules directly (i.e. GOPROXY=off).

CVE-2023-39326 [MEDIUM] CVE-2023-39326: A malicious HTTP sender can use chunk extensions to cause a receiver reading from a request or respo A malicious HTTP sender can use chunk extensions to cause a receiver reading from a request or response body to read many more bytes from the network than are in the body. A malicious HTTP client can further exploit this to cause a server to automatically read a large amount of data (up to about 1GiB) when a handler fails to read the entire body of a reques

CVE-2023-45287 [HIGH] CWE-203 CVE-2023-45287: Before Go 1.20, the RSA based TLS key exchanges used the math/big library, which is not constant tim 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 PKCS#1 padding may leak timing information, which in turn could be used to recover session ke
