osslsigncode 2.3

2.3 (2022.03.06)

CRITICAL SECURITY VULNERABILITIES

This release fixes several critical memory corruption vulnerabilities.
A malicious attacker could create a file, which, when processed with
osslsigncode, triggers arbitrary code execution. Any previous version
of osslsigncode should be immediately upgraded if the tool is used for
processing of untrusted files.

• fixed several memory safety issues
• fixed non-interactive PVK (MSBLOB) key decryption
• added a bash completion script
• added CA bundle path auto-detection

osslsigncode 2.2

  for handling of all the needed MSI metadata, such as dates
• "-untrusted" option renamed to "-TSA-CAfile"
• "-CRLuntrusted" option renamed to "-TSA-CRLfile"
• numerous bug fixes and improvements
