1) Buffer overflow

EUVDB-ID: #VU12343

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-2007-0455

CWE-ID: CWE-120 - Buffer overflow

Exploit availability: No

Description

The vulnerability allows a remote attacker to cause DoS condition or execute arbitrary code on the target system.

The weakness exists in the gdImageStringFTEx function in gdft.c due to buffer overflow. A remote attacker can cause the service to crash or execute arbitrary code via a specially crafted string with a JIS encoded font.

Successful exploitation of the vulnerability may result in system comprmise.

Mitigation
