It was found that jq, a lightweight and flexible command-line JSON parser, was vulnerable to multiple memory corruption attacks, which could lead to application crashes, denial-of-service conditions, and potentially arbitrary code execution through heap corruption when parsing untrusted input.
For Debian 11 bullseye, these problems have been fixed in version 1.6-2.1+deb11u2.
We recommend that you upgrade your jq packages.
For the detailed security status of jq please refer to its security tracker page at:
