Name of the Vulnerable Software and Affected Versions
UltraVNC revision 1198
Description
The issue is related to multiple memory leaks in VNC client code, allowing an attacker to read stack memory, which can be used for information disclosure. When combined with another vulnerability, it can leak stack memory and bypass ASLR. This attack is exploitable via network connectivity.
Recommendations
For UltraVNC revision 1198, update to revision 1199 to resolve the issue. As a temporary workaround, consider restricting network connectivity to minimize the risk of exploitation.
