CVSS v3.1
7.5
High
| Vector | AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
proglottis Go wrapper versions prior to 0.1.1
Description
The issue is related to a use-after-free problem, which can cause a crash or potentially allow code execution during GPG signature verification. This is due to improper memory management, where memory passed to C may be freed before it is used, leading to crashes or possible code execution.
Recommendations
For proglottis Go wrapper versions prior to 0.1.1, update to version 0.1.1 or later to resolve the issue. As a temporary workaround, consider disabling GPG signature verification until a patch is available. Restrict access to the GPGME library to minimize the risk of exploitation. Avoid using the proglottis Go wrapper for container image pulls by Docker or CRI-O until the issue is resolved.
