Detailsinfo

A vulnerability, which was classified as critical, was found in GNU binutils 2.30 (Programming Tool Software). Affected is the function display_debug_ranges of the file dwarf.c. The manipulation as part of a ELF File leads to a integer overflow vulnerability. CWE is classifying the issue as CWE-190. 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 can introduce other weaknesses when the calculation is used for resource management or execution control. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

The display_debug_ranges function in dwarf.c in GNU Binutils 2.30 allows remote attackers to cause a denial of service (integer overflow and application crash) or possibly have unspecified other impact via a crafted ELF file, as demonstrated by objdump.
