CVE-2023-42811— AEADs/aes-gcm: Plaintext exposed in decrypt_in_place_detached even on tag verification failure

Quick assessment

Affected
RustCrypto AEADs
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

aes-gcm是aes-gcm开源的一种加密算法。 aes-gcm 0.10.0至0.10.3之前版本存在数据伪造问题漏洞，该漏洞源于在AES GCM解密实现中，即使标签验证失败，也会以decrypt_in_place_detached形式公开明文。

Vulnerability Title
AEADs/aes-gcm: Plaintext exposed in decrypt_in_place_detached even on tag verification failure
Source: CVE Program / CVE List V5
Vulnerability Description
aes-gcm is a pure Rust implementation of the AES-GCM. Starting in version 0.10.0 and prior to version 0.10.3, in the AES GCM implementation of decrypt_in_place_detached, the decrypted ciphertext (i.e. the correct plaintext) is exposed even if tag verification fails. If a program using the `aes-gcm` crate's `decrypt_in_place*` APIs accesses the buffer after decryption failure, it will contain a decryption of an unauthenticated input. Depending on the specific nature of the program this may enable Chosen Ciphertext Attacks (CCAs) which can cause a catastrophic breakage of the cipher including full plaintext recovery. Version 0.10.3 contains a fix for this issue.
