  - GNU binutils gold gold v1.11-v1.16 (GNU binutils v2.21-v2.31.1) is affected by: Improper Input Validation,     Signed/Unsigned Comparison, Out-of-bounds Read. The impact is: Denial of service. The component is:
    gold/fileread.cc:497, elfcpp/elfcpp_file.h:644. The attack vector is: An ELF file with an invalid e_shoff     header field must be opened. (CVE-2019-1010204)

  - 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.
    (CVE-2021-3530)

  - Heap/stack buffer overflow in the dlang_lname function in d-demangle.c in libiberty allows attackers to     potentially cause a denial of service (segmentation fault and crash) via a crafted mangled symbol.
    (CVE-2021-3826)

  - stab_xcoff_builtin_type in stabs.c in GNU Binutils through 2.37 allows attackers to cause a denial of     service (heap-based buffer overflow) or possibly have unspecified other impact, as demonstrated by an out-     of-bounds write. NOTE: this issue exists because of an incorrect fix for CVE-2018-12699. (CVE-2021-45078)

  - GCC v12.0 was discovered to contain an uncontrolled recursion via the component libiberty/rust-demangle.c.
    This vulnerability allows attackers to cause a Denial of Service (DoS) by consuming excessive CPU and     memory resources. (CVE-2021-46195)

  - libiberty/rust-demangle.c in GNU GCC 11.2 allows stack consumption in demangle_const, as demonstrated by     nm-new. (CVE-2022-27943)

  - In GNU Binutils before 2.40, there is a heap-buffer-overflow in the error function bfd_getl32 when called     from the strip_main function in strip-new via a crafted file. (CVE-2022-38533)
