CVE-2022-1292

Status Candidate

Overview

The c_rehash script does not properly sanitise shell metacharacters to prevent command injection. This script is distributed by some operating systems in a manner where it is automatically executed. On such operating systems, an attacker could execute arbitrary commands with the privileges of the script. Use of the c_rehash script is considered obsolete and should be replaced by the OpenSSL rehash command line tool. Fixed in OpenSSL 3.0.3 (Affected 3.0.0,3.0.1,3.0.2). Fixed in OpenSSL 1.1.1o (Affected 1.1.1-1.1.1n). Fixed in OpenSSL 1.0.2ze (Affected 1.0.2-1.0.2zd).

Ubuntu Security Notice 5402-1 - Elison Niven discovered that OpenSSL incorrectly handled the c_rehash script. A local attacker could possibly use this issue to execute arbitrary commands when c_rehash is run. Raul Metsma discovered that OpenSSL incorrectly verified certain response signing certificates. A remote attacker could possibly use this issue to spoof certain response signing certificates. This issue only affected Ubuntu 22.04 LTS.

OpenSSL is a robust, fully featured Open Source toolkit implementing the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols with full-strength cryptography world-wide. The 3.x series is the current major version of OpenSSL.

Changes: Fixed a bug in the c_rehash script which was not properly sanitizing shell metacharacters to prevent command injection. Fixed a bug in the function OCSP_basic_verify that verifies the signer certificate on an OCSP response. Fixed a bug where the RC4-MD5 ciphersuite incorrectly used the AAD data as the MAC key. Fixed a bug in the OPENSSL_LH_flush() function that breaks reuse of the memory occupied by the removed hash table entries.
