Vulnerability identifier: #VU13240

CSH Severity: Low

CVSS v4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2017-7607

CWE-ID: CWE-122

Exploitation vector: Remote access

Exploit availability: No public exploit available

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

The vulnerability exists in the handle_gnu_hash function of elfutils due to heap-based buffer overflow when handling of Executable and Linkable Format (ELF) files by the handle_gnu_hash function, as defined in the readelf.c source code file. A remote attacker can trick the victim into opening an Executable and Linkable Format (ELF) file that submits malicious input, trigger memory corruption and cause the application to crash.
