FreeBSD 安全漏洞

FreeBSD is a Unix-like operating system developed by the FreeBSD Foundation. FreeBSD has security vulnerabilities; these vulnerabilities arise from the tcpsetmss process, which may release data packets and cause errors without stopping the rule processing engine. This can lead to null pointer...

FreeBSD 安全漏洞

FreeBSD is a Unix-like operating system developed by the FreeBSD Foundation. FreeBSD has a security vulnerability that stems from the rtsockmsgbuffer function not verifying the length field of the source sockaddr. This can lead to a stack buffer overflow, potentially causing a kernel crash...

FreeBSD 安全漏洞

FreeBSD is a Unix-like operating system developed by the FreeBSD Foundation.

📄 FreeBSD Routing Socket Input Validation

This proof of concept exploit attempts to test the robustness of the FreeBSD routing socket subsystem by crafting a RTMADD message containing an intentionally oversized sockaddr structure salen greater than the traditional sockaddrstorage limit of 128 bytes...

FreeBSD -- Jail chroot escape via fd exchange with a different jail

Problem Description: If two sibling jails are restricted to separate filesystem trees, which is to say that neither of the two jail root directories is an ancestor of the other, jailed processes may nonetheless be able to access a shared directory via a nullfs mount, if the administrator has...

FreeBSD -- Local DoS and possible privilege escalation via routing sockets

Problem Description: The rtsockmsgbuffer function serializes routing information into a buffer. As a part of this, it copies sockaddr structures into a sockaddrstorage structure on the stack. It assumes that the source sockaddr length field had already been validated, but this is not necessarily...
