FreeBSD : FreeBSD -- Information leak in kldstat(2) (759059ac-dab3-11e7-b5af-a4badb2f4699)

The kernel does not properly clear the memory of the kldfilestat structure before filling the data. Since the structure filled by the kernel is allocated on the kernel stack and copied to userspace, a leak of information from the kernel stack is possible. Impact : Some bytes from the kernel stack...

FreeBSD 10.3 / 10.4 / 11.0 / 11.1 : ptrace / kldstat Information Disclosure Vulnerabilities (FreeBSD-SA-17:08.ptrace) (FreeBSD-SA-17:10.kldstat)

The version of the FreeBSD kernel running on the remote host is prior to 10.3-RELEASE-p24, 10.4 prior to 10.4-RELEASE-p3, 11.0 prior to 11.0-RELEASE-p15, or 11.1 prior to 11.1-RELEASE-p4. It is, therefore, affected by a potential information disclosure vulnerabilities in ptrace and kldstat. An...

FreeBSD -- netgraph / bluetooth privilege escalation

Problem Description: Some function pointers for netgraph and bluetooth sockets are not properly initialized. Impact: A local user can cause the FreeBSD kernel to execute arbitrary code. This could be used by an attacker directly; or it could be used to gain root privilege or to escape from a jail...
