FreeBSD Security Advisory - FreeBSD-SA-26:31.arm64

FreeBSD Security Advisory - 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...

FreeBSD Security Advisory - FreeBSD-SA-26:36.ldns

FreeBSD Security Advisory - 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...

FreeBSD Security Advisory - FreeBSD-SA-26:32.elf

FreeBSD Security Advisory - 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...

FreeBSD Security Advisory - FreeBSD-SA-26:28.capsicum

FreeBSD Security Advisory - 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...

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...
