CVE-2019-8277

What is CVE-2019-8277?

UltraVNC revision 1211 suffers from multiple memory leaks in its VNC server implementation, leading to stack memory exposure. An adversary could exploit these leaks to gain unauthorized access to sensitive information, especially when paired with additional vulnerabilities that could allow bypassing Address Space Layout Randomization (ASLR). This risk is particularly concerning given the potential for remote exploitation through network connectivity. The issue has been rectified in revision 1212, highlighting the importance of maintaining updated software to mitigate security risks.
