A vulnerability, which was classified as problematic, has been found in GNU binutils 2.29 (Programming Tool Software). Affected by this issue is the function process_version_sections of the file readelf.c. The manipulation as part of a Binary File leads to a integer overflow vulnerability. Using CWE to declare the problem leads to 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. Impacted is availability. CVE summarizes:

The process_version_sections function in readelf.c in GNU Binutils 2.29 allows attackers to cause a denial of service (Integer Overflow, and hang because of a time-consuming loop) or possibly have unspecified other impact via a crafted binary file with invalid values of ent.vn_next, during "readelf -a" execution.
