[Bug binutils/30793] kvx_reassemble_bundle index 8 out of bounds
https://sourceware.org/bugzilla/show_bug.cgi?id=30793 --- Comment #2 from cvs-commit at gcc dot gnu.org --- The master branch has been updated by Alan Modra : https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=dd39dcae8880f0ed298daa1e35d21a84f0a7bdec commit dd39dcae8880f0ed298daa1e35d21a84f0a7bdec Author: Alan Modra Date: Thu Sep 7 20:08:57 2023 +0930 PR30793, kvx_reassemble_bundle index 8 out of bounds While the patch already committed for pr30793 prevents the asan error, there is a problem: Now the last element of bundle_words never gets written. That's very likely wrong, or KVXMAXBUNDLEWORDS is too big. So this patch rearranges things a little to support writing of all of bundle_words and does the parallel bit checking only when filling bundle_words. In the normal case, kvx_reassemble_bundle will see bundle_words[word_count-1] with the parallel bit clear and all other words having it set. In the error case where all words in bundle_words have the parallel bit set, kvx_reassemble_bundle will be passed a wordcount of KVXMAXBUNDLEWORDS + 1. I've also made kvx_reassemble_bundle return true for success rather than zero, and removed the unnecessary check for zero wordcount. PR 30793 * kvx-dis.c (kvx_reassemble_bundle): Return bool, true on success. Fail if wordcount is too large. Don't check for wordcount zero. Don't check kvx_has_parallel_bit. (print_insn_kvx): Rewrite code reading bundle_words as a for loop. Don't stop reading at KVXMAXBUNDLEWORDS - 1. (decode_prologue_epilogue_bundle): Similarly. -- You are receiving this mail because: You are on the CC list for the bug.

[Bug binutils/30830] New: stripping PE binary fails to delete security directory entry
https://sourceware.org/bugzilla/show_bug.cgi?id=30830 Bug ID: 30830 Summary: stripping PE binary fails to delete security directory entry Product: binutils Version: 2.41 Status: UNCONFIRMED Severity: normal Priority: P2 Component: binutils Assignee: unassigned at sourceware dot org Reporter: medhefgo at web dot de Target Milestone: --- Given a signed PE/EFI binary, running `strip` on it will remove the signatures contained in it, but leave the security data directory entry inside the PE optional header as-is. This renders the binary unbootable as it gets rejected by firmware/EDK2. Using signed grub2 from debian as example: $ qemu-system-x86_64 -bios /usr/share/edk2/x64/OVMF.fd -kernel grubx64.efi.signed (This boots to grub cmdline.) $ strip grubx64.efi.signed $ sbverify --list grubx64.efi.signed warning: checksum areas are greater than image size. Invalid section table? No signature table present $ qemu-system-x86_64 -bios /usr/share/edk2/x64/OVMF.fd -kernel grubx64.efi.signed (Fails to boot grub.) Manually changing the security directory pointer and size to 0 will allow booting again and also make sbverify happy again. -- You are receiving this mail because: You are on the CC list for the bug.
