+Subject: [PATCH] Fix bsdtar zero-length pattern issue.
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Uses the sed-like way (and Java-like, and .Net-like, and Javascript-like…) to fix this issue of advancing the string to be processed by one if the match is zero-length.
+
+Fixes libarchive/libarchive#2725 and solves libarchive/libarchive#2438.
+
+CVE: CVE-2025-60753
+Upstream-Status: Backport [https://github.com/libarchive/libarchive/commit/3150539edb18690c2c5f81c37fd2d3a35c69ace5]
