Detailsinfo

A vulnerability, which was classified as problematic, has been found in GNU binutils 2.30 (Programming Tool Software). Affected by this issue is the function concat_filename of the file dwarf2.c of the component libbfd. The manipulation with an unknown input 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. CVE summarizes:

concat_filename in dwarf2.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.30, allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted binary file, as demonstrated by nm-new.
