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.

An illegal memory access flaw was found in the binutils package. Parsing an ELF file containing corrupt symbol version information may result in a denial of service. This issue is the result of an incomplete fix for CVE-2020-16599.

A potential heap based buffer overflow was found in bfdelfslurpversiontables() in bfd/elf.c. This may lead to loss of availability.

A flaw was found in binutils readelf 2.35 program. An attacker who is able to convince a victim using readelf to read a crafted file could trigger a stack buffer overflow, out-of-bounds write of arbitrary data supplied by the attacker. The highest impact of this flaw is to confidentiality, integrity, and availability.
