FreeBSD : FreeBSD -- Uninitialized kernel memory disclosure via ktrace(2) (2830b374-debd-11ef-87ba-002590c1f29c)

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 2830b374-debd-11ef-87ba-002590c1f29c advisory. In some cases, the ktrace facility will log the contents of kernel structures to userspace. In one such...

FreeBSD -- Uninitialized kernel memory disclosure via ktrace(2)

Problem Description: In some cases, the ktrace facility will log the contents of kernel structures to userspace. In one such case, ktrace dumps a variable-sized sockaddr to userspace. There, the full sockaddr is copied, even when it is shorter than the full size. This can result in up to 14...

FreeBSD : FreeBSD -- ktrace(2) fails to detach when executing a setuid binary (8fb61d94-771b-11ef-9a62-002590c1f29c)

CVE-2024-6760

CVE-2024-6760 describes a logic bug in FreeBSD's ktrace which disables kernel tracing for setuid programs. The flaw allows unprivileged users to trace and inspect the behavior of setuid binaries, potentially reading files they normally should not access (e.g., the local password database). Connec...

CVE-2024-6760 ktrace(2) fails to detach when executing a setuid binary

A logic bug in the code which disables kernel tracing for setuid programs meant that tracing was not disabled when it should have, allowing unprivileged users to trace and inspect the behavior of setuid programs. The bug may be used by an unprivileged user to read the contents of files to which...

FreeBSD : FreeBSD -- ktrace kernel memory disclosure (6e04048b-6007-11e6-a6c3-14dae9d210b8)

Due to an overlooked merge to -STABLE branches, the size for page fault kernel trace entries was set incorrectly. Impact : A user who can enable kernel process tracing could end up reading the contents of kernel memory. Such memory might contain sensitive information, such as portions of the file...

CVE-2014-3873

The ktrace utility in the FreeBSD kernel 8.4 before p11, 9.1 before p14, 9.2 before p7, and 9.3-BETA1 before p1 uses an incorrect page fault kernel trace entry size, which allows local users to obtain sensitive information from kernel memory via a kernel process trace...

CVE-2014-3873

The CVE-2014-3873 issue affects FreeBSD where the ktrace kernel tracing entry size was set incorrectly for 8.4 (before p11), 9.1 (before p14), 9.2 (before p7), and 9.3-BETA1 (before p1). This allows a local user with kernel process tracing enabled to read contents of kernel memory (e.g., file cac...
