+Subject: [PATCH] archive/tar: limit size of headers
+
+Set a 1MiB limit on special file blocks (PAX headers, GNU long names,
+GNU link names), to avoid reading arbitrarily large amounts of data
+into memory.
+
+Thanks to Adam Korczynski (ADA Logics) and OSS-Fuzz for reporting
+this issue.
+
+Fixes CVE-2022-2879
+Updates #54853
+Fixes #55925
