Package        : jq
Version        : 1.6-2.1+deb11u3
CVE ID         : CVE-2026-43894 CVE-2026-47770 CVE-2026-49839 CVE-2026-54679
Debian Bug     : 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 11 bullseye, these problems have been fixed in version
1.6-2.1+deb11u3.

We recommend that you upgrade your jq packages.

For the detailed security status of jq please refer to
its security tracker page at:
