Libqb · Libqb · CVE-2023-39976
**Name of the Vulnerable Software and Affected Versions**
libqb versions prior to 2.0.8
**Description**
The issue is related to a buffer overflow in the log blackbox.c component of the libqb library. This occurs due to the lack of input size validation when copying data, allowing an attacker to potentially execute arbitrary code remotely. The buffer overflow is triggered by long log messages because the header size is not considered.
**Recommendations**
For versions prior to 2.0.8, update to version 2.0.8 or later to resolve the issue. As a temporary workaround, consider restricting the length of log messages to prevent exploitation until a patch is applied.
