AlienVault OTX Vulnerabilities

AlienVault OTX Malware

A flaw was found in X.Org server. Both DeviceFocusEvent and the XIQueryPointer reply contain a bit for each logical button currently down. Buttons can be arbitrarily mapped to any value up to 255, but the X.Org Server was only allocating space for the device's particular number of buttons, leading to a heap overflow if a bigger value was used.

CVE-2023-6816 is a critical security vulnerability identified in the X.Org server component of Red Hat Enterprise Linux 6 Extended Lifecycle Support (ELS). The vulnerability stems from improper memory allocation when handling input device button states. Specifically, the DeviceFocusEvent and XIQueryPointer reply messages contain bits representing the state of each logical button currently pressed. While buttons can be mapped to any value up to 255, the X.Org server only allocates memory based on the device's reported number of buttons, which is typically much smaller. This discrepancy allows an attacker to craft input events with button values exceeding the allocated buffer size, resulting in a heap overflow. Such an out-of-bounds write can corrupt memory, potentially leading to arbitrary code execution with no privileges required and no user interaction needed. The vulnerability is remotely exploitable over the network, as the X.Org server listens for input device events. The CVSS v3.1 base score of 9.8 reflects the critical impact on confidentiality, integrity, and availability, combined with ease of exploitation. Although no known exploits have been reported in the wild, the vulnerability poses a significant risk to systems running RHEL 6 ELS with X.Org server enabled. The lack of patch links suggests that mitigation may require vendor updates or workarounds. This vulnerability is particularly concerning for legacy systems that remain in use due to extended lifecycle support commitments.
