Detailsinfo

A vulnerability was found in GNU binutils 2.28 (Programming Tool Software). It has been declared as problematic. Affected by this vulnerability is the function process_mips_specific of the file readelf.c of the component ELF File Handler. The manipulation with an unknown input leads to a null pointer dereference vulnerability. The CWE definition for the vulnerability is 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. As an impact it is known to affect availability. The summary by CVE is:

GNU Binutils 2017-04-03 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash), related to the process_mips_specific function in readelf.c, via a crafted ELF file that triggers a large memory-allocation attempt.
