Freebsd: Security Vulnerabilities
Multiple race conditions in (1) certain rules and (2) argument copying during VM protection, in CerbNG for FreeBSD 4.8 allow local users to defeat system call interposition and possibly gain privileges or bypass auditing, as demonstrated by modifying command lines in log-exec.cb.

CerbNG for FreeBSD 4.8 does not properly implement VM protection when attempting to prevent system call wrapper races, which allows local users to have an unknown impact related to an "incorrect write protection of pages".

archive_read_support_format_tar.c in libarchive before 2.2.4 allows user-assisted remote attackers to cause a denial of service (crash) via (1) an end-of-file condition within a tar header that follows a pax extension header or (2) a malformed pax extension header in an (a) PAX or a (b) TAR archive, which results in a NULL pointer dereference, a different issue than CVE-2007-3644.

archive_read_support_format_tar.c in libarchive before 2.2.4 does not properly compute the length of a certain buffer when processing a malformed pax extension header, which allows user-assisted remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted (1) PAX or (2) TAR archive that triggers a buffer overflow.

archive_read_support_format_tar.c in libarchive before 2.2.4 allows user-assisted remote attackers to cause a denial of service (infinite loop) via (1) an end-of-file condition within a pax extension header or (2) a malformed pax extension header in an (a) PAX or a (b) TAR archive.

The ULE process scheduler in the FreeBSD kernel gives preference to "interactive" processes that perform voluntary sleeps, which allows local users to cause a denial of service (CPU consumption), as described in "Secretly Monopolizing the CPU Without Superuser Privileges."

The 4BSD process scheduler in the FreeBSD kernel performs scheduling based on CPU billing gathered from periodic process sampling ticks, which allows local users to cause a denial of service (CPU consumption) by performing voluntary nanosecond sleeps that result in the process not being active during a clock interrupt, as described in "Secretly Monopolizing the CPU Without Superuser Privileges."
