Detailsinfo

A vulnerability was found in GNU binutils 2.28 (Programming Tool Software) and classified as problematic. This issue affects the function main of the file elflink.c of the component BFD Library. The manipulation as part of a File Descriptor leads to a null pointer dereference vulnerability. Using CWE to declare the problem leads to CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. Impacted is availability. The summary by CVE is:

elflink.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.28, has a "member access within null pointer" undefined behavior issue, which might allow remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via an "int main() {return 0;}" program.
