+Subject: [PATCH] Fix server-controlled unbounded MD5 loop in FTP OPIE
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+* src/ftp-basic.c (ftp_login): Limit the skey sequence to 9999.
+
+Report:
+wget accepts an unbounded server-controlled integer as the iteration
+count for its OPIE/S-KEY MD5 key-derivation loop. No upper bound is
+enforced on the sequence number supplied by the server in the FTP
+challenge line. The value is passed directly to skey_response() as a
+loop counter, causing wget to perform up to ~2.1 billion full MD5
+computations before responding to the authentication challenge.
+
+Reported-by: Michał Majchrowicz and Marcin Wyczechowski
+
+CVE: CVE-2026-16599
+
+Upstream-Status: Backport [https://gitlab.com/gnuwget/wget/-/commit/e9697d98e7249b0f68a6be040a4f3dcc5bc101fa]
