CVE-2003-0525: Microsoft Windows Nt

Medium severity, CVSS 5.0. EPSS: 7.7% chance of exploitation in the next 30 days.

The getCanonicalPath function in Windows NT 4.0 may free memory that it does not own and cause heap corruption, which allows attackers to cause a denial of service (crash) via requests that cause a long file name to be passed to getCanonicalPath, as demonstrated on the IBM JVM using a long string to the java.io.getCanonicalPath Java method.

Affected products

• Microsoft Windows Nt: version 4.0 only
