The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the c3a9c5a6-4435-11f1-bb07-bc241121aa0a advisory. When processing the header of an incoming message, libnv failed to properly validate the message size...

FreeBSD : FreeBSD -- pf can overflow the stack parsing crafted SCTP packets (225ba563-4435-11f1-bb07-bc241121aa0a)

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 225ba563-4435-11f1-bb07-bc241121aa0a advisory. Incorrect packet validation allowed unbounded recursion parsing SCTP chunk parameters. This can...

FreeBSD : FreeBSD -- Local privilege escalation via execve() (f528ea29-4434-11f1-bb07-bc241121aa0a)

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the f528ea29-4434-11f1-bb07-bc241121aa0a advisory. An operator precedence bug in the kernel results in a scenario where a buffer overflow causes...

FreeBSD : FreeBSD -- Remotely triggerable out-of-bounds heap write in dhclient (58acf4c5-4435-11f1-bb07-bc241121aa0a)

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 58acf4c5-4435-11f1-bb07-bc241121aa0a advisory. As dhclient is building an environment to pass to dhclient-script, it may need to resize the array of...

FreeBSD Security Advisory - FreeBSD-SA-26:15.dhclient

FreeBSD Security Advisory - As dhclient is building an environment to pass to dhclient-script, it may need to resize the array of string pointers. The code which expands the array incorrectly calculates its new size when requesting memory, resulting in a heap buffer overrun...

Incorrect packet validation allowed unbounded recursion parsing SCTP chunk parameters. This can eventually result in a stack overflow and panic. Remote attackers can craft packets which cause affected systems to panic. This affects any system where pf is configured to process traffic, independent...
