CVE-2017-8397

The Binary File Descriptor BFD library aka libbfd, as distributed in GNU Binutils 2.28, is vulnerable to an invalid read of size 1 and an invalid write of size 1 during processing of a corrupt binary containing relocs with negative addresses. This vulnerability causes programs that conduct an...

CVE-2017-8394

The Binary File Descriptor BFD library aka libbfd, as distributed in GNU Binutils 2.28, is vulnerable to an invalid read of size 4 due to NULL pointer dereferencing of bfdelflargecomsection. This vulnerability causes programs that conduct an analysis of binary programs using the libbfd library,...

CVE-2017-8392

The Binary File Descriptor BFD library aka libbfd, as distributed in GNU Binutils 2.28, is vulnerable to an invalid read of size 8 because of missing a check to determine whether symbols are NULL in the bfddwarf2findnearestline function. This vulnerability causes programs that conduct an analysis...

CVE-2017-8421

The function coffsetalignmenthook in coffcode.h in Binary File Descriptor BFD library aka libbfd, as distributed in GNU Binutils 2.28, has a memory leak vulnerability which can cause memory exhaustion in objdump via a crafted PE file. Additional validation in dumprelocsinsection in objdump.c can...

Design/Logic Flaw

The Binary File Descriptor BFD library aka libbfd, as distributed in GNU Binutils 2.28, is vulnerable to an invalid read of size 1 because the existing reloc offset range tests didn't catch small negative offsets less than the size of the reloc field. This vulnerability causes programs that condu...

Design/Logic Flaw

The Binary File Descriptor BFD library aka libbfd, as distributed in GNU Binutils 2.28, is vulnerable to a global buffer over-read error because of an assumption made by code that runs for objcopy and strip, that SHTREL/SHRRELA sections are always named starting with a .rel/.rela prefix. This...
