Freebsd: >> Freebsd >> 6.0 Security Vulnerabilities
Buffer overflow in the sppp driver in FreeBSD 4.11 through 6.1, NetBSD 2.0 through 4.0 beta before 20060823, and OpenBSD 3.8 and 3.9 before 20060902 allows remote attackers to cause a denial of service (panic), obtain sensitive information, and possibly execute arbitrary code via crafted Link Control Protocol (LCP) packets with an option length that exceeds the overall length, which triggers the overflow in (1) pppoe and (2) ippp. NOTE: this issue was originally incorrectly reported for the ppp driver.

Directory traversal vulnerability in smbfs smbfs on FreeBSD 4.10 up to 6.1 allows local users to escape chroot restrictions for an SMB-mounted filesystem via "..\\" sequences. NOTE: this is similar to CVE-2006-1864, but this is a different implementation of smbfs, so it has a different CVE identifier.

The build process for ypserv in FreeBSD 5.3 up to 6.1 accidentally disables access restrictions when using the /var/yp/securenets file, which allows remote attackers to bypass intended access restrictions.

The Linux kernel before 2.6.16.9 and the FreeBSD kernel, when running on AMD64 and other 7th and 8th generation AuthenticAMD processors, only save/restore the FOP, FIP, and FDP x87 registers in FXSAVE/FXRSTOR when an exception is pending, which allows one process to determine portions of the state of floating point instructions of other processes, which can be leveraged to obtain sensitive information such as cryptographic keys. NOTE: this is the documented behavior of AMD64 processors, but it is inconsistent with Intel processors in a security-relevant fashion that was not addressed by the kernels.

opiepasswd in One-Time Passwords in Everything (OPIE) in FreeBSD 4.10-RELEASE-p22 through 6.1-STABLE before 20060322 uses the getlogin function to determine the invoking user account, which might allow local users to configure OPIE access to the root account and possibly gain root privileges if a root shell is permitted by the configuration of the wheel group or sshd.

A "programming error" in fast_ipsec in FreeBSD 4.8-RELEASE through 6.1-STABLE and NetBSD 2 through 3 does not properly update the sequence number associated with a Security Association, which allows packets to pass sequence number checks and allows remote attackers to capture IPSec packets and conduct replay attacks.

FreeBSD kernel 5.4-STABLE and 6.0 does not completely initialize a buffer before making it available to userland, which could allow local users to read portions of kernel memory.

A logic error in FreeBSD kernel 5.4-STABLE and 6.0 causes the kernel to calculate an incorrect buffer length, which causes more data to be copied to userland than intended, which could allow local users to read portions of kernel memory.

A logic error in the IP fragment cache functionality in pf in FreeBSD 5.3, 5.4, and 6.0, and OpenBSD, when a 'scrub fragment crop' or 'scrub fragment drop-ovl' rule is being used, allows remote attackers to cause a denial of service (crash) via crafted packets that cause a packet fragment to be inserted twice.
