Security Bulletin

This security bulletin contains one low risk vulnerability.

1) Out-of-bounds read

EUVDB-ID: #VU50329

Risk: Low

CVSSv4.0: [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2019-25013

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

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

The vulnerability exists due to a boundary condition in GNU C Library within the iconv feature when processing multi-byte input sequences in the EUC-KR encoding. A remote attacker can pass specially crafted input to the application, trigger out-of-bounds read error and perform a denial of service (DoS) attack.

Mitigation

Cybersecurity Help is currently unaware of any official solution to address this vulnerability.
