CVE-2020-35448

An issue was discovered in the Binary File Descriptor BFD library aka libbfd, as distributed in GNU Binutils 2.35.1. A heap-based buffer over-read can occur in bfdgetlsigned32 in libbfd.c because shentsize is not validated in bfdelfslurpsecondaryrelocsection in elf.c...

There is an open race window when writing output in the following utilities in GNU binutils version 2.35 and earlier:ar objcopy strip ranlib. When these utilities are run as a privileged user (presumably as part of a script updating binaries across different users) an unprivileged user can trick these utilities into getting ownership of arbitrary files through a symlink.
