+Subject: [PATCH] PR24689, string table corruption
+
+The testcase in the PR had a e_shstrndx section of type SHT_GROUP.
+hdr->contents were initialized by setup_group rather than being read
+from the file, thus last byte was not zero and string dereference ran
+off the end of the buffer.
+
+        PR 24689
+        * elfcode.h (elf_object_p): Check type of e_shstrndx section.
+
+Upstream-Status: Backport
