-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 OpenSSL Security Advisory [21 June 2022] ======================================== The c_rehash script allows command injection (CVE-2022-2068) ============================================================ Severity: Moderate In addition to the c_rehash shell command injection identified in CVE-2022-1292, further circumstances where the c_rehash script does not properly sanitise shell metacharacters to prevent command injection were found by code review. When the CVE-2022-1292 was fixed it was not discovered that there are other places in the script where the file names of certificates being hashed were possibly passed to a command executed through the shell. 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. This issue affects OpenSSL versions 1.0.2, 1.1.1 and 3.0. OpenSSL 1.0.2 users should upgrade to 1.0.2zf (premium support customers only) OpenSSL 1.1.1 users should upgrade to 1.1.1p OpenSSL 3.0 users should upgrade to 3.0.4 This issue was reported to OpenSSL on the 20th May 2022. It was found by Chancen of Qingteng 73lab. A further instance of the issue was found by Daniel Fiala of OpenSSL during a code review of the script. The fix for these issues was developed by Daniel Fiala and Tomas Mraz from OpenSSL. Note ==== OpenSSL 1.0.2 is out of support and no longer receiving public updates. Extended support is available for premium support customers: https://www.openssl.org/support/contracts.html OpenSSL 1.1.0 is out of support and no longer receiving updates of any kind. The impact of these issues on OpenSSL 1.1.0 has not been analysed. Users of these versions should upgrade to OpenSSL 3.0 or 1.1.1.
