An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.32. There is a heap-based buffer over-read in bfddoprnt in bfd.c because elfobjectp in elfcode.h mishandles an eshstrndx section of type SHTGROUP by omitting a trailing '\0' character.

An issue was discovered in GNU libiberty, as distributed in GNU Binutils 2.32. simpleobjectelfmatch in simple-object-elf.c does not check for a zero shstrndx value, leading to an integer overflow and resultant heap-based buffer overflow.

An issue was discovered in GNU libiberty, as distributed in GNU Binutils 2.32. It is a stack consumption issue in dcounttemplatesscopes in cp-demangle.c after many recursive calls.

An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.32. It is an out-of-bounds read leading to a SEGV in bfdgetl32 in libbfd.c, when called from pex64getruntimefunction in pei-x8664.c.

An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.32. It is an attempted excessive memory allocation in bfdelfslurpversiontables in elf.c.

An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.32. It is an integer overflow leading to a SEGV in bfddwarf2findnearestline in dwarf2.c, as demonstrated by nm.

findabstractinstance in dwarf2.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.32, allows remote attackers to cause a denial of service (infinite recursion and application crash) via a crafted ELF file.

applyrelocations in readelf.c in GNU Binutils 2.32 contains an integer overflow that allows attackers to trigger a write access violation (in byteputlittleendian function in elfcomm.c) via an ELF file, as demonstrated by readelf.
