Description

This security bulletin contains information about 1 vulnerability.


1) Input validation error (CVE-ID: CVE-2010-2547)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: 6.3 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N]


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

The vulnerability exists due to insufficient validation of user-supplied input.
