Description John Helmert III archtester

2023-04-03 03:46:16 UTC

CVE-2023-25076:
https://github.com/dlundquist/sniproxy/commit/f8d9a433fe22ab2fa15c00179048ab02ae23d583

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.

Talos gave us a fix in the CVE for once. Please bump to 0.6.1.
