Vulnerability Details : CVE-2018-6323
Potential exploit
The elf_object_p function in elfcode.h in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29.1, has an unsigned integer overflow because bfd_size_type multiplication is not used. A crafted ELF file allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact.

CWE ids for CVE-2018-6323
-
The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.Assigned by: nvd@nist.gov (Primary)
