Package : nginx
Debian Bug : 1147527
The update for nginx released as DSA 6496-1 caused a regression in the
nginx-dev package: the backported fix for CVE-2026-42533 declared two
private header files, which are not shipped in nginx-dev, as
dependencies of the module build, so third-party nginx modules could no
longer be built against nginx-dev. Updated nginx packages are now
available to correct this issue.
For the stable distribution (trixie), this problem has been fixed in
version 1.26.3-3+deb13u9.
We recommend that you upgrade your nginx packages.
