Name of the Vulnerable Software and Affected Versions SNIProxy versions 0.6.0-2 through the master branch (commit: 822bb80df9b7b345cc9eba55df74a07b498819ba)

Description A buffer overflow vulnerability exists in the handling of wildcard backend hosts of SNIProxy. A specially crafted HTTP or TLS packet can lead to arbitrary code execution. An attacker could send a malicious packet to trigger this vulnerability.

Recommendations For SNIProxy versions 0.6.0-2, consider disabling the handling of wildcard backend hosts until a patch is available. For the master branch (commit: 822bb80df9b7b345cc9eba55df74a07b498819ba), restrict access to the vulnerable code path to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
