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.
AnalysisAI
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. Rated high severity (CVSS 7.8), this vulnerability is no authentication required, low attack complexity. No vendor patch available.
Technical ContextAI
This vulnerability is classified as Integer Overflow (CWE-190), which allows attackers to cause unexpected behavior through arithmetic overflow. 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. Affected products include: Gnu Binutils, Redhat Enterprise Linux Desktop, Redhat Enterprise Linux Server, Redhat Enterprise Linux Workstation.
RemediationAI
No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Validate arithmetic operations, use safe integer libraries, check bounds before allocation.
