[Hetvi Thakar -X (hthakar - E INFOCHIPS PRIVATE LIMITED at Cisco)]

From: Hetvi Thakar <hthakar@cisco.com>

This patch applies the upstream fix as referenced in [2],
using the commit shown in [1].

It also includes the upstream follow-up fixes referenced in [3]
and [4]. These correct the trailing whitespace check introduced
by the original fix and add the required <ctype.h> include for
isspace().

+Subject: [PATCH] * src/metalink.c (clean_metalink_string): Fix inverted
+ trailing-space check
+
+37a40fcb added an `end > beg' bound guard to prevent a buffer
+underflow, but accidentally flipped the condition from `isspace' to
+`!isspace'. The loop therefore walked back over non-space characters
+instead of trailing whitespace, collapsing any string without a
+trailing newline to "". Every Metalink/HTTP resource URL was wiped,
+so wget could not follow any mirror and
+testenv/Test-metalink-http.py failed ("Expected file test.meta not
+found"). Restore the `isspace' condition.

+Subject: [PATCH] Regression: Fix buffer overflow in html_quote_string()
+
+The regression has been introduced in commit dd692d9 and
+is not part of any release.
+
+The tests allow the address sanitizer to find the issue.
+
+* src/convert.c: Fix string size calculation.
+* tests/unit-tests.c: Added tests including tests for html_quote_string().
+* tests/unit-tests.h: Add definitions for the test functions.

Hi,

I reviewed the earlier series.
It looks like the follow-up upstream regression fixes for
CVE-2026-58469 and CVE-2026-58472 were not included in the backport.
These follow-up commits are required to complete the backport, and I
have included them in my series .
I kindly request you to review my series as well.

Thanks,
Hetvi Thakar

Hello,

I can choose to continue with your series indeed but it lacks a
corresponding master series.
Amaury's series[0] on master has the same issue as this one. So I doubt it
will merge in this v1 state.

Can you help review/fix the series on master? Then, I'll consider your
series.

Thanks!

Hello,

The master patch you sent contained a regression fix that is not in this
wrynose version (also not in your scarthgap version).

Can you send a v2 with the regression fix?

Thanks!

Hi,

Thanks for pointing this out.

I will include the regression fix in both the wrynose and scarthgap
patches and send the updated v2 versions.
