In GNU Binutils 2.30, there's an integer overflow in the function loadspecificdebugsection() in objdump.c, which results in malloc() with 0 size. A crafted ELF file allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact.

In GNU Binutils through version 2.30, the coffpointerizeaux function in coffgen.c in the Binary File Descriptor (BFD) library (aka libbfd), an index is not properly validated, allowing an attacker to cause a denial of service via a crash (segmentation fault) when parsing a file with a crafted COFF file.

concatfilename in dwarf2.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.30, allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted binary file, as demonstrated by nm-new.
An issue was discovered in cplus-dem.c in GNU libiberty, as distributed in GNU Binutils 2.30. Stack Exhaustion occurs in the C++ demangling functions provided by libiberty, and there are recursive stack frames: demangletemplatevalueparm, demangleintegralvalue, and demangleexpression.
The assignfilepositionsfornonloadsections function in elf.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.30, allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via an ELF file with a RELRO segment that lacks a matching LOAD segment, as demonstrated by objcopy.
The elfparsenotes function in elf.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.30, allows remote attackers to cause a denial of service (out-of-bounds read and segmentation violation) via a note with a large alignment.
A flaw was found in the parsedie function in dwarf1.c in the Binary File Descriptor (BFD) library (aka libbfd) as distributed in GNU Binutils up to version 2.30, when compiled in 32bit mode. This vulnerability allows attackers to cause a denial of service (integer overflow and application crash) via an ELF file with corrupted dwarf1 debug information.

A flaw was found in the bfdXXbfdcopyprivatebfddatacommon function in peXXigen.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.30, processes a negative Data Directory size with an unbounded loop that increases the value of (externalIMAGEDEBUGDIRECTORY) edd so that the address exceeds its own memory region, resulting in an out-of-bounds memory write, as demonstrated by objcopy copying private info with bfdpex64bfdcopyprivatebfddatacommon in pex64igen.c.

An issue was discovered in cplus-dem.c in GNU libiberty, as distributed in GNU Binutils 2.29 and 2.30. Stack Exhaustion occurs in the C++ demangling functions provided by libiberty, and there are recursive stack frames: demanglenestedargs, demangleargs, doarg, and dotype.
binutils through version 2.30 has a vulnerability in the elf.c:bfdsectionfromshdr() functionof the Binary File Descriptor (BFD) library (aka libbfd). An attacker could exploit this with a crafted executable file to cause a crash.

GNU Binutils through version 2.30 has a heap-based buffer over-read vulnerability in dwarf.c:processcutuindex(). An attacker could exploit this to crash the readelf application by providing a binary file.

A flaw was found in the readattributevalue function in dwarf2.c file in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils up to version 2.30, when compiled in 32bit mode. This allows attackers to cause a denial of service (integer wraparound and application crash) via an ELF file with a corrupt DWARF FORM block.

A flaw was found in the ignoresectionsym function in elf.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.30, does not validate the outputsection pointer in the case of a symtab entry with a "SECTION" type that has a "0" value, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted file, as demonstrated by objcopy.

A flaw was found in The Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.30, allows remote attackers to cause a denial of service (excessive memory allocation and application crash) via a crafted ELF file. This can occur during execution of nm.
