CVE-2023-45287 (GCVE-0-2023-45287)

Vulnerability from cvelistv5 – Published: 2023-12-05 16:18 – Updated: 2025-02-13 17:14

Title

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

Summary

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 key bits. In Go 1.20, the crypto/tls library switched to a fully constant time RSA implementation, which we do not believe exhibits any timing side channels.

Severity ?

No CVSS data available.

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 key bits. In Go 1.20, the crypto/tls library switched to a fully constant time RSA implementation, which we do not believe exhibits any timing side channels."

CVE-2023-39326 (GCVE-0-2023-39326)

Vulnerability from cvelistv5 – Published: 2023-12-06 16:27 – Updated: 2025-02-13 17:02

Title

Denial of service via chunk extensions in net/http

Summary

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 request. Chunk extensions are a little-used HTTP feature which permit including additional metadata in a request or response body sent using the chunked encoding. The net/http chunked encoding reader discards this metadata. A sender can exploit this by inserting a large metadata segment with each byte transferred. The chunk reader now produces an error if the ratio of real body to encoded bytes grows too small.

Severity ?

No CVSS data available.

CVE-2024-21626 (GCVE-0-2024-21626)

Vulnerability from cvelistv5 – Published: 2024-01-31 21:31 – Updated: 2025-05-15 16:02

Title

runc container breakout through process.cwd trickery and leaked fds

Summary

runc is a CLI tool for spawning and running containers on Linux according to the OCI specification. In runc 1.1.11 and earlier, due to an internal file descriptor leak, an attacker could cause a newly-spawned container process (from runc exec) to have a working directory in the host filesystem namespace, allowing for a container escape by giving access to the host filesystem ("attack 2"). The same attack could be used by a malicious image to allow a container process to gain access to the host filesystem through runc run ("attack 1"). Variants of attacks 1 and 2 could be also be used to overwrite semi-arbitrary host binaries, allowing for complete container escapes ("attack 3a" and "attack 3b"). runc 1.1.12 includes patches for this issue.

Severity ?

8.6 (High)
