Description Sam James archtester gentoo-dev Security 2021-05-27 00:00:36 UTC
Description:
"An out of bounds flaw was found in GNU binutils objdump utility version 2.36. An attacker could use this flaw and pass a large section to avr_elf32_load_records_from_section() probably resulting in a crash or in some cases memory corruption. The highest threat from this vulnerability is to integrity as well as system availability."

CVE-2021-3530

A flaw was discovered in GNU libiberty within demangle_path() in rust-demangle.c, as distributed in GNU Binutils version 2.36. A crafted symbol can cause stack memory to be exhausted leading to a crash.

I assume this is https://gcc.gnu.org/bugzilla/show_bug.cgi?id=99935
(which is fixed in binutils-2.37)
