A buffer overflow vulnerability exists in the handling of wildcard backend hosts of SNIProxy 0.6.0-2 and the master branch (commit: 822bb80df9b7b345cc9eba55df74a07b498819ba). A specially crafted HTTP or TLS packet can lead to arbitrary code execution. An attacker could send a malicious packet to trigger this vulnerability.

The remote Ubuntu 18.04 ESM / 20.04 LTS / 22.04 LTS / 23.04 host has a package installed that is affected by a vulnerability as referenced in the USN-6148-1 advisory.

    It was discovered that SNI Proxy did not properly handle wildcard backend hosts. An attacker could     possibly use this issue to cause a buffer overflow, resulting in a denial of service, or arbitrary code     execution.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote Debian 11 host has a package installed that is affected by a vulnerability as referenced in the dsa-5413 advisory.
