FreeBSD -- Integer overflow in vt(4) CONS_HISTORY ioctl

Problem Description: The CONSHISTORY ioctl handler did not adequately validate the requested history size. A large value caused an integer overflow in the buffer size calculation, resulting in a heap allocation smaller than expected. Subsequent initialization of the buffer wrote beyond the end of...

FreeBSD -- Flaw in Linuxulator execution of setugid binaries

Problem Description: The Linuxulator determined whether a binary was set-user-ID or set-group-ID by checking the PSUGID process flag. During execve2, this flag is not yet set at the point where the auxiliary vector is constructed, so ATSECURE was incorrectly set to zero for set-user-ID and...

FreeBSD -- Arbitrary file overwrite via the KTLS receive path

Problem Description: The KTLS receive path decrypted each record in place, assuming that the mbufs holding received data were anonymous and safe to modify. This assumption does not hold for data placed on a socket by sendfile2, which can reference file-backed memory directly through non-anonymous...

FreeBSD -- Insufficient response validation in the ldns stub resolver

Problem Description: When used as a stub resolver over UDP, ldns failed to verify that a received response belonged to the outstanding query. It did not check that the response source address and port matched the query destination, that the transaction ID matched, or that the question section of...

FreeBSD -- Arm CPU errata may bypass page table permission changes

Problem Description: Some Arm CPUs have errata where the ordering of stores and the TLBI+DSB sequence may be incorrect. If one CPU stores to a virtual address while another CPU invalidates the translation for that address, the second CPU's TLBI+DSB may complete before the first CPU's store has be...

FreeBSD-kernel -- ASLR bypass for setuid executables via procctl(2)

Problem Description: The ELF image activator cleared per-process ASLR preference flags for setuid binaries after the code that computes the PIE base address, rather than before. As a result, a user-requested ASLR disable was still in effect at the point where the base address was chosen. Impact: ...

FreeBSD -- Use-after-free bug in the IPV6_MSFILTER socket option handler

Problem Description: The kernel handler for IPV6MSFILTER dropped a serializing lock in order to copy the source-filter list from userspace, then reacquired the lock. During this window another thread could free the multicast filter structure, leaving the handler with a stale pointer to freed...

FreeBSD -- sigqueue(2) missing capability mode restriction

Problem Description: sigqueue2 was marked as permitted in capability mode with the introduction of Capsicum in 2011, but the implementation of kernsigqueue did not include a capability mode check restricting signal delivery to the calling process's own PID. Impact: A process in capability mode ca...

FreeBSD -- Missing permission check in thr_kill2(2)

Problem Description: When used to deliver a signal to a specific thread, thrkill22 called pcansignal to determine whether the operation was permitted but did not check the result before delivering the signal. The signal was sent even when the permission check failed. The system call returned the...

FreeBSD -- Multiple vulnerabilities in the sound(4) mmap path

Problem Description: The sound4 driver contained two memory-safety errors in its mmap2 support. First, dspmmapsingle validated the requested mapping by checking the sum of the user-supplied offset and length against the buffer size. This addition could overflow, so that a large offset and length...

strongSwan -- Double-free when destroying certain cloned identities that can lead to remote code execution

R. Elliott Childre reports: The clone method of the identificationt class doesn't correctly handle identities that have an empty but non-NULL encoding.
