Vulnerability details

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists in the libelf component due to improper handling of Executable and Linkable Format (ELF) files by the read_long_names function, as defined in the elf_begin.c source code file. A remote attacker can trick the victim into accessing an ELF file that submits malicious input and cause the affected application to improperly allocate excessive memory resources, resulting in a DoS condition.
