+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Description: Fix for CVE-2017-16516
+ Potential buffer overread: A JSON file can cause denial of service.
+Origin: https://github.com/brianmario/yajl-ruby/commit/a8ca8f476655adaa187eedc60bdc770fff3c51ce
+Bug-Debian: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1040036
+Bug: https://github.com/lloyd/yajl/issues/248
+
+Patch taken from Debian package source
+
+NB, Fedora code can't trigger the reported aborts since it passes the
+-DNDEBUG flag, but pulling the fix for robustness in case a future
+change enables the assert()s.

+Subject: [PATCH 6/8] Fix CVE-2022-24795
+
+There was an integer overflow in yajl_buf_ensure_available() leading
+to allocating less memory than requested. Then data were written past
+the allocated heap buffer in yajl_buf_append(), the only caller of
+yajl_buf_ensure_available(). Another result of the overflow was an
+infinite loop without a return from yajl_buf_ensure_available().
+
+yajl-ruby project, which bundles yajl, fixed it
+<https://github.com/brianmario/yajl-ruby/pull/211> by checking for the
+integer overflow, fortifying buffer allocations, and report the
+failures to a caller. But then the caller yajl_buf_append() skips
+a memory write if yajl_buf_ensure_available() failed leading to a data
+corruption.
+
+A yajl fork mainter recommended calling memory allocation callbacks with
+the large memory request and let them to handle it. But that has the
+problem that it's not possible pass the overely large size to the
+callbacks.
+
+This patch catches the integer overflow and terminates the process
+with abort().
