Security Bulletin

This security bulletin contains information about 11 vulnerabilities.

1) Stack-based buffer overflow

EUVDB-ID: #VU12110

Risk: High

CVSSv4.0: 8.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2017-10684

CWE-ID: CWE-121 - Stack-based buffer overflow

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists in the fmt_entry function of ncurses due to stack-based buffer overflow when handling malicious input. A remote unauthenticated attacker can send a request that submits malicious input, trigger memory corruption and execute arbitrary code with elevated privileges.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Mitigation

Install update from vendor's website.
