Mageia: 2021-0341 Critical: Binutils Memory and Symlink Issues

This update provides binutils 2.36.1 and fixes atleast the following security issues:
There's a flaw in the BFD library of binutils in versions before 2.36. An attacker who supplies a crafted file to an application linked with BFD, and using the DWARF functionality, could cause an impact to system availability by way of excessive memory consumption (CVE-2021-3487).
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 (CVE-2021-20197).
For more info about the 2.36 update, see the sourceware link.
