Ubuntu Security Notice 6148-1 - 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.
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, TLS or DTLS packet can lead to arbitrary code execution. An attacker could send a malicious packet to trigger this vulnerability.
An attacker could exploit this vulnerability by sending a specially crafted HTTP, TLS or DTLS packet to the target machine, potentially causing a denial of service or gaining the ability to execute remote code.
