A flaw was found in the way certificate signatures could be forged using
collisions found in the SHA-1 algorithm. An attacker could use this
weakness to create forged certificate signatures. This issue affects GnuPG
versions before 2.2.18.
Bugs
Notes
| Author | Note |
|---|---|
| mdeslaur | in master, gnupg disables SHA-1 signatures completely. In the 2.2 branch, it disables SHA-1 signatures after a certain date only. |
| rodrigo-zaiden | As of 2022-03-22 there is no upstream patch available for gnupg 1.4 series. Backporting from 2.2 would be too risky. |
