In fact it's a bug in the chkproc. We are working on it to be fixed in the next chkrootkit version (0.48).

I. Background The random(4) and urandom(4) devices return an endless supply of pseudo-random bytes when read. Cryptographic algorithms often depend on the secrecy of these pseudo-random values for security. II. Problem Description Under certain circumstances, a bug in the internal state tracking on the random(4) and urandom(4) devices can be exploited to allow replaying of data distributed during subsequent reads. III. Impact This could enable an adversary to determine fragments of random values previously read, allowing them to defeat certain security mechanisms. Note that the attacker has to be in close proximity to the source of the pseudo-randomness, which typically means local access to the system. IV. Workaround No workaround is available. V. Solution Perform one of the following: 1) Upgrade your vulnerable system to 5-STABLE, or 6-STABLE, or to the RELENG_6_2, RELENG_6_1, or RELENG_5_5 security branch dated after the correction date. 2) To patch your present system: The following patches have been verified to apply to FreeBSD 5.5, 6.1, and 6.2 systems. a) Download the relevant patch from the location below, and verify the detached PGP signature using your PGP utility. # fetch http://security.FreeBSD.org/patches/SA-07:09/random.patch # fetch http://security.FreeBSD.org/patches/SA-07:09/random.patch.asc b) Apply the patch. # cd /usr/src # patch < /path/to/patch c) Recompile your kernel as described in and reboot the system.

I. Background GNU tar (gtar) is a utility to create and extract "tape archives", commonly known as tar files. GNU tar is included in FreeBSD 5.x as /usr/bin/gtar. II. Problem Description Insufficient sanity checking of paths containing '.' and '..' allows gtar to overwrite arbitrary files on the system. III. Impact An attacker who can convince an user to extract a specially crafted archive can overwrite arbitrary files with the permissions of the user running gtar. If that user is root, the attacker can overwrite any file on the system. IV. Workaround Use "bsdtar", which has been the default tar implementation since FreeBSD 5.3. V. Solution Perform one of the following: 1) Upgrade your vulnerable system to 5-STABLE, or to the RELENG_5_5 security branch dated after the correction date. 2) To patch your present system: The following patches have been verified to apply to FreeBSD 5.5 systems. a) Download the relevant patch from the location below, and verify the detached PGP signature using your PGP utility. # fetch http://security.FreeBSD.org/patches/SA-07:10/gtar.patch # fetch http://security.FreeBSD.org/patches/SA-07:10/gtar.patch.asc b) Execute the following commands as root: # cd /usr/src # patch < /path/to/patch # cd /usr/src/gnu/usr.bin/tar # make obj && make depend && make && make install VI.
