Description
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper handling of Executable and Linkable Format (ELF) files by the ebl_object_note function, as defined in the eblobjnote.c source code file. A remote attacker can trick the victim into opening a specially crafted ELF file that submits malicious input, trigger a buffer over-read condition and cause the affected application to crash, resulting in a DoS condition.
