Vulnerability identifier: #VU17697

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-2019-7664

CWE-ID: CWE-119

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 due to improper overflow checks by the elf_cvt_note function, as defined in the libelf/note_xlate.h 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 affected application to crash, resulting in a DoS condition.
