Description Avinash Hanwate 2026-08-31 17:49:19 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

libcurl had a flaw that when instructed to clear proxy authentication
credentials which made it not do so, leaving the old credentials around to get
used for subsequent transfers that should not know nor use them.

trustee-guest-components does not directly use (lib)curl

fedpkg  clone -a trustee-guest-components
cd trustee-guest-components/
fedpkg prep
find trustee-guest-components-0.17.0-build/guest-components-0.17.0/ -name Cargo.toml -exec grep -i curl {} \; # empty
grep -i curl -l  -R trustee-guest-components-0.17.0-build/ # only .md files are shown
