Package: release.debian.org
Severity: normal
X-Debbugs-Cc: golang-golang-x-net@packages.debian.org
Control: affects -1 + src:golang-golang-x-net
User: release.debian.org@packages.debian.org
Usertags: unblock
Please unblock package golang-golang-x-net
[ Reason ]
The patch fixes a FTBFS due to a failing test (#1089192) and adds to
fixes for CVEs.
[ Impact ]
downstream build dependencies are affected by the CVEs and users can't
easily modify and build the package.
[ Tests ]
Recompiled a couple times with sbulid and ran autopkgtests to make sure
it work now.
[ Risks ]
Low, The skipped test has no impact compared to the version in testing
and the patches for the two CVEs are from upstream and applied without
problems.
[ Checklist ]
[X] all changes are documented in the d/changelog
[X] I reviewed all changes and I approve them
[X] attach debdiff against the package in testing
[ Other info ]
As this is a source only -dev package we probably need to recompile all
downstream build dependencies to make user the CVEs fixes are applied.

+Subject: html: properly handle trailing solidus in unquoted attribute value
+ in foreign content
+
+The parser properly treats tags like <p a=/> as <p a="/">, but the
+tokenizer emits the SelfClosingTagToken token incorrectly. When the
+parser is used to parse foreign content, this results in an incorrect
+DOM.
+
+Thanks to Sean Ng (https://ensy.zip) for reporting this issue.

+Subject: html: use strings.EqualFold instead of lowering ourselves
+
+Instead of using strings.ToLower and == to check case insensitive
+equality, just use strings.EqualFold, even when the strings are only
+ASCII. This prevents us unnecessarily lowering extremely long strings,
+which can be a somewhat expensive operation, even if we're only
+attempting to compare equality with five characters.
+
+Thanks to Guido Vranken for reporting this issue.

+
+Bug-Debian: https://bugs.debian.org/1089192
+Forwarded: not-needed
+Last-Update: 2025-05-03
+
+These tests are hardcoded by upstream to check against parts of the test data,
+but break when the test data is regenerated from the latest publicsuffix data,
+which is constantly changing.
+
+This patch skips TestPublicSuffix, TestSlowPublicSuffix, TestNumICANNRules,
+ExamplePublicSuffix_manager, and TestICANN, which are all affected by this
+problem and resulted in test failures.
