60c7185cf42783788adfe98d69d8c473FreeBSD Security Advisory: Multiple problems in crypto(3)
d6e58d7e1bd57fb91fc562d092c9cb67FreeBSD Security Advisory - BIND 9 suffers from multiple denial of service vulnerabilities.
8417e3c29fcdaa164cdf36aa7fc72fa1FreeBSD Security Advisory - When verifying a PKCS#1 version 1.5 signature, OpenSSL ignores any bytes which follow the cryptographic hash being signed. In a valid signature there will be no such bytes.
566eca5458df286607558cd7ea7fe723FreeBSD Security Advisory - While processing Link Control Protocol (LCP) configuration options received from the remote host, ppp fails to correctly validate option lengths. This may result in data being read or written beyond the allocated kernel memory buffer.
e2f563d2dd4b544cc0d5325972985e5eFreeBSD Security Advisory FreeBSD-SA-06:16.smbfs: smbfs does not properly sanitize paths containing a backslash character; in particular the directory name '..\' is interpreted as the parent directory by the SMB/CIFS server, but smbfs handles it in the same manner as any other directory.
6b5fe29e9c5f65d1e385ac5d1c9cce4bFreeBSD Security Advisory FreeBSD-SA-06:15.ypserv: There are two documented methods of restricting access to NIS maps through ypserv(8): through the use of the /var/yp/securenets file, and through the /etc/hosts.allow file. While both mechanisms are implemented in the server, a change in the build process caused the "securenets" access restrictions to be inadvertently disabled.
29a262f243bd13cb49baa342002bac1cFreeBSD Security Advisory FreeBSD-SA-06:14.fpu - FPU information disclosure: On affected processors, a local attacker can monitor the execution path of a process which uses floating-point operations. This may allow an attacker to steal cryptographic keys or other sensitive information.
d416397c0cde6ec1455f60ec239ed5c6FreeBSD-SA-06:13.sendmail - A remote attacker may be able to execute arbitrary code with the privileges of the user running sendmail, typically root.
6c86c0c2dcd02084ebd0b9cb562865c3FreeBSD-SA-06:12.opie - The opiepasswd(1) program uses getlogin(2) to identify the user calling opiepasswd(1). In some circumstances getlogin(2) will return "root" even when running as an unprivileged user. This causes opiepasswd(1) to allow an unpriviled user to configure OPIE authentication for the root user.
a879cb7f04f38109a9c6770703b3deabFreeBSD-SA-06:11.ipsec - An attacker able to to intercept IPSec packets can replay them. If higher level protocols which do not provide any protection against packet replays (e.g., UDP) are used, this may have a variety of effects.
00eb28e85d0a0489882135b4ee99b007FreeBSD-SA-06:07.pf - IP fragment handling panic in pf(4)
f2ff92106829bc72041425d6489cb82dFreeBSD-SA-06:06.kmem - Local kernel memory disclosure.
c0be0dc046041baf3b8db0b2bb86d1baFreeBSD-SA-06:05.80211 - An integer overflow in the handling of corrupt IEEE 802.11 beacon or probe response frames when scanning for existing wireless networks can result in the frame overflowing a buffer.
4d1a3110984d5ddd807e56852b3fd6baFreeBSD Security Advisory FreeBSD-SA-05-20.cvsbug - A temporary file is created, used, deleted, and then re-created with the same name. This creates a window during which an attacker could replace the file with a link to another file.
144795693624779ec7d30b825746ea02The SIOCGIFCONF ioctl, used to request the kernel to produce a list of interfaces, can be exploited to reveal 12 bytes of memory. It is not at all guaranteed that this memory will contain anything interesting.
66eb4676bc3cd1b2175f219366017011OpenSSL below v0.9.7c contain remotely exploitable vulnerabilities. More information available here.
ed545da67a8f598d19279038ec39de28FreeBSD Security Advisory FreeBSD-SA-03:07 - A second remotely exploitable overflow was found in Sendmail header parsing. Upgrade to 8.12.9 to fix the vulnerability. Patch available here.
454fb0ba212f0f2c02a50a53699667f4FreeBSD Security Advisory FreeBSD-SA-03:04.sendmail - ISS has identified a buffer overflow that may occur during header parsing in all versions of sendmail after version 5.79 through v8.12.7. Patch available here.
282a5839a77da73bf290adf649ac1a1cFreeBSD Security Advisory FreeBSD-SA-03:02 Version 1.1 - OpenSSL v0.9.6h and below contains a timing-based vulnerability in CBC ciphersuites in SSL and TLS which can recover fixed plaintext blocks, like a password.
8c581cda70ad432693cef8f9ee3def2eFreeBSD Security Advisory FreeBSD-SA-03:03 - The FreeBSD syncookie implementation uses keys that are only 32 bits in length, allowing remote attackers to recover the ISN, which can be valid for up to four seconds, allowing ACL's to be bypassed and TCP connections forged. syncookies may be disabled using the 'net.inet.tcp.syncookies' sysctl(8) by running the following command as root: "sysctl net.inet.tcp.syncookies=0".
c63d88b8c3ba56ae9ba89de75ec0918eFreeBSD Security Advisory FreeBSD-SA-03:01 - It has been found that the CVS server can be tricked to free memory more then once, which can be used for remote code execution. Additionally, the CVS server allowed clients with write access to specify arbitrary commands to execute as part of an update (update-prog) or commit (checkin-prog). This behavior has been restricted. This affects all FreeBSD versions prior to 4.6-RELEASE-p7, 4.7-RELEASE-p4 and 5.0-RELEASE-p1.
ccd2161dff5274f9b0a3ec177c73b23eFreeBSD Security Advisory FreeBSD-SA-02:44 - FreeBSD 4.3 and later is vulnerable to a local denial service attack due to a bug in the fpathconf system call which crashes the system by repeatedly calling fpathconf on a file descriptor until the reference count wraps to a negative value, then closing the file descriptor. See Pine-cert-20030101.txt for more information.
afc45e10c1049f4c6192cae828f02f2dFreeBSD Security Advisory FreeBSD-SA-02:43.bind - BIND 8 has two vulnerabilities. The BIND SIG Cached RR overflow allows a remote attacker to force a server with recursion enabled to execute arbitrary code with the privileges of the name server process. The BIND OPT DoS and BIND SIG Expiry Time DoS may cause a remote name server to crash.
692cf77764884df59e8d5338ab9fa59fFreeBSD Security Advisory FreeBSD-SA-02:41 - The sendmail Restricted Shell command (smrsh) contains errors in the handling of command arguments with "||" or spaces which allow the execution of commands outside of those in its target directory. Since command arguments may be specified in local users' .forward' files, the smrsh restrictions may be bypassed using such files that are specially crafted.
