Debian Bug     : 1133921 1136445

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 12 bookworm, these problems have been fixed in version
1.6-2.1+deb12u2.

For Debian 11 bullseye, these issues have been addressed in DLA-4599-1 and
DLA-4661-1.
  
We recommend that you upgrade your jq packages.
