Description

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The vulnerability exists in the __libelf_set_rawdata_wrlock function of elfutils due to boundary error when hhandling of sh_off and sh_size Executable and Linkable Format (ELF) header values by the __libelf_set_rawdata_wrlock function, as defined in the elf_getdata.c source code file. A remote attacker can trick the victim into opening an ELF file that submits malicious sh_off or sh_size ELF header values, trigger memory corruption and cause the application to crash.

Mitigation
