          "details": "Not affected: CVE-2026-22184 targets only the contrib/untgz demonstration utility (untgz.c), and the zlib source used here (Debian’s DFSG-repacked zlib_1.2.11.dfsg.orig.tar.gz) has excluded contrib/untgz since 1:1.2.3.5.dfsg-1, so neither the vulnerable code nor any untgz binary is present. ELS source inspection shows only contrib/minizip, contrib/testzlib, and README.contrib, with no TGZfname/untgz references. Debian classifies this CVE for zlib as “unimportant” due to the utility not being built, and Ubuntu lists zlib as “Not affected,” aligning with the absence of the affected code in this package.",
