Description

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: 4.0, 4.0-sp1, 4.0-sp2, 4.0-sp3, 4.0-sp4, 4.0-sp5 (+2)
