FreeBSD-SA-02:06.sudo |
Description:
|
FreeBSD Security Advisory FreeBSD-SA-02:06 - The sudo port prior to sudo-1.6.4.1 contains a local root vulnerability. If a user who has not been authorized by the system administrator (listed in the `sudoers' file) attempts to use sudo, sudo will send an email alert. When it does so, it invokes the system mailer with superuser privileges, and with most of the user's environment intact.

FreeBSD-SA-00:44.xlockmore |
Description:
|
FreeBSD Security Advisory FreeBSD-SA-00:44 - The xlockmore port, versions 4.17 and below, installs the setuid root binary xlock, which contains a vulnerability due to incorrect use of the syslog() function. The xlock program correctly drops root privileges prior to the point of vulnerability, however it may retain in memory part of the hashed password database for the user accounts on the system. Attackers who can retrieve hashed password information from the memory space of the process can mount attacks against the user account passwords and possibly gain access to accounts on the system if successful.

FreeBSD Security Advisory FreeBSD-SA-01:11 - The ident server included with FreeBSD inetd contains a vulnerability which allows remote users to read the first 16 bytes of files which are accessible by group wheel. The inetd internal ident server is not enabled by default - if you have not enabled the ident portion of inetd, you are not vulnerable.

FreeBSD-SA-00:73.thttpd |
Description:
|
FreeBSD Security Advisory FreeBSD-SA-00:73 - The thttpd port, versions prior to 2.20, allows remote viewing of arbitrary files on the local server. The 'ssi' cgi script does not correctly restrict URL-encoded requests containing ".." in the path. In addition, the cgi script does not have the same restrictions as the web server for preventing requests outside of the web root. These two flaws allow remote users to access any file on the system accessible to the web server user (user 'nobody' in the default configuration).

FreeBSD-SA-00:57.muh |
Description:
|
FreeBSD Security Advisory FreeBSD-SA-00:57 - The muh port, an IRC bouncer, versions 2.05c and below contains a vulnerability which allows remote users to gain the privileges of the user running muh. This is accomplished by sending a carefully crafted exploit string containing string format operators to a user using muh but who is not connected. When the user reconnects and executes '/muh read', muh will allow the remote attacker to execute arbitrary code as the local user.

FreeBSD-SA-02:02.pw |
Description:
|
FreeBSD Security Advisory FreeBSD-SA-02:02 - When creating, removing, or modifying system users, the pw utility modifies the system password file `/etc/master.passwd'. This file contains the users' encrypted passwords and is normally only readable by root. During the modification, a temporary copy of the file is created. However, this temporary file is mistakenly created with permissions that allow it to be read by any user. A race condition is created.

FreeBSD-SA-02:36.nfs |
Description:
|
FreeBSD Security Advisory FreeBSD-SA-02:36 - A denial of service vulnerability has been discovered in FreeBSD NFS. A part of the NFS server code charged with handling incoming RPC messages had an error which, when the server received a message with a zero-length payload, would cause it to reference the payload from the previous message, creating a loop in the message chain. This would later cause an infinite loop in a different part of the NFS server code which tried to traverse the chain.

Only the first signature encountered is actually verified, meaning that other data with invalid signatures (e.g. data which has been tampered with by an attacker) will not be verified, and the entire document will be treated as having valid signatures.

FreeBSD-SA-00:20 - The MIT Kerberos 5 port version 1.1.1 and earlier contains remote and local root vulnerabilities. Note that the implementations of Kerberos shipped in the FreeBSD base system is not the MIT version and not vulnerable to these problems. However, a very old release of FreeBSD dating from 1997 (FreeBSD 2.2.5) did ship with a closely MIT-derived Kerberos implementation ("eBones") and may be vulnerable to attacks of the kind described here.

FreeBSD-SA-00:22 - A patch added to the FreeBSD SSH port on 2000-01-14 incorrectly configured the SSH daemon to listen on an additional network port, 722, in addition to the usual port 22. This may cause a violation of security policy if the additional port is not subjected to the same access-controls (e.g. firewallling) as the standard SSH port.
