FreeBSD-SA-01:07.xfree86 |
Description:
|
FreeBSD Security Advisory FreeBSD-SA-01:07 - The XFree86-3.3.6 port, versions prior to 3.3.6_1, has multiple vulnerabilities that may allow local or remote users to cause a denial of service attack against a vulnerable X server. Additionally, local users can often obtain elevated privileges. A malformed packet to TCP port 6000 causes the X server to freeze for several minutes. Due to various coding flaws in libX11, privileged programs linked against libX11 allow local users to obtain privileged access. In addition, any application using libICE to listen on a network port can be crashed due to inadequate bounds checking in libICE.

FreeBSD-SA-01:08.ipfw |
Description:
|
FreeBSD Security Advisory FreeBSD-SA-01:08 - A vulnerability in ipfw and ip6fw allows bypassing of firewalls which make use of the 'established' qualifier, such as "allow tcp from any to any established". Due to overloading of the TCP reserved flags field, ipfw incorrectly treats all TCP packets with the ECE flag set as being part of an established TCP connection, which will therefore match a corresponding ipfw rule containing the 'established' qualifier, even if the packet is not part of an established connection. The ECE flag is part of an experimental extension to TCP. At least one other major operating system will emit TCP packets with the ECE flag set under certain operating conditions. All released versions of FreeBSD prior to the correction date including FreeBSD 3.5.1 and FreeBSD 4.2 are vulnerable.

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-01:12.periodic |
Description:
|
FreeBSD Security Advisory FreeBSD-SA-01:12 - Periodic, a program to run periodic system functions, uses tempfiles insecurely. This allows a malicious local user to cause arbitrary files on the system to be corrupted. In a default state, periodic is normally called by cron for daily, weekly, and monthly maintenance. Because these scripts run as root, an attacker may potentially corrupt any file on the system.

FreeBSD-SA-01:30.ufs-ext2fs |
Description:
|
FreeBSD Security Advisory FreeBSD-SA-01:30.ufs-ext2fs - A bug in the UFS filesystem allows users to obtain access to areas of the filesystem containing data from deleted files. The filesystem code is supposed to ensure that all filesystem blocks are zeroed before becoming available to user processes, but in a certain specific case this zeroing does not occur, and unzeroed blocks are passed to the user with their previous contents intact. Thus, if the block contains data which used to be part of a file or directory to which the user did not have access, the operation results in unauthorized access of data.
