 Package : jq Version : 1.6-2.1+deb12u2 CVE ID : CVE-2026-32316 CVE-2026-33947 CVE-2026-33948 CVE-2026-39956 CVE-2026-39979 CVE-2026-40164 CVE-2026-41256 CVE-2026-41257 CVE-2026-43894 CVE-2026-43895 CVE-2026-43896 CVE-2026-44777 CVE-2026-47770 CVE-2026-49839 CVE-2026-54679 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.

 For the detailed security status of jq please refer to its security tracker page at:
 https://security-tracker.debian.org/tracker/jq

Solution

Upgrade the jq packages.
