ISS Security Advisory - Snort v1.8 through 1.9.0 contains a remote root vulnerability in the processing of fragmented RPC traffic. Since fragment sizes are not properly checked against the remaining buffer space, remote attackers can execute arbitrary code as root by sending a packet to any IP in network space a snort sensor is listening to. Successful exploitation does not generate log entries, and non-executable stacks do not offer protection.
9586718047fb1b5adb1e3adb78451830ISS Security Advisory - The "Microsoft SQL Slammer Worm" is spreading via unpatched SQL servers. Once a vulnerable computer is compromised, the worm will infect that target, randomly select a new target, and resend the exploit and propagation code to that host sending a large amount of network traffic in the process which crashes some network equipment.
6ddebac702eda1acef91bb54c7773882ISS Security Advisory - Bind 8 v8.3.3-REL and below and Bind 4 v4.9.10-REL and below contain a flaw in the formation of DNS responses containing SIG resource records (RR) that allows remote code execution. Two denial of service vulnerabilities exist as well. A workaround is available by turning off recursive DNS functionality.
17867314448a7d78bc9b1ebb770928cdISS Security Advisory - A vulnerability found in the manner used by Internet Scanner to parse certain types of non-standard HTTP responses can result in a remotely exploitable buffer overflow condition. This affects Internet Scanner version 6.2.1 for Windows (NT/2000) and has been corrected with X-Press Update 6.17.
59a67df3aadbf955c0bd2e782c368f5dISS Security Advisory - Polycom ViewStation videoconferencing products contain several remote vulnerabilities which allow attackers to gather information about the device, retrieve files, crash the device, and monitor videoconferences. Polycom ViewStation 7.2 and earlier and Polycom ViewStation FX/VS 4000 version 4.1.5 and below are affected.
4aa04177e96055df305f827067346d7cISS Security Advisory - Windows NT, 2000, and XP can be crashed remotely by sending a malformed packet to port 139, triggering a heap overflow. MS02-045.
c1a41e51ef34733065164f72ef91735dISS Security Advisory - Microsoft Exchange Server v5.5 contains a remotely exploitable buffer overflow. This flaw allows attackers to either crash Exchange and block all inbound and outbound email delivery or allow an attacker to gain complete control of the server.
ae145c1d4f7894ecbafc5ad974e6533aISS Security Advisory - ISS X-Force has discovered a vulnerability in the HP-UX line printer daemon (rlpdaemon) that allows a remote or local user to execute arbitrary code with root privileges. Affected versions include HP-UX 10.01, 10.10, 10.20, 11.00, and 11.11.
43096382e2e5ba6caf7ba296e2418260ISS discovered a buffer overflow vulnerability in the Subprocess Control Server (dtspcd) in all Unix variants running CDE (Common Desktop Environment) system. The vulnerability in the dtspcd daemon allows remote attackers to execute arbitrary commands on a target system as root. Many unix flavors are affected.
beea66f63139c599a9961d27013d248fISS Security Advisory - A remote denial of service vulnerability has been found in Citrix MetaFrame, an application server that works with Windows Terminal Services. This vulnerability causes a MetaFrame installation to crash or "blue screen" and requires an affected system to be restarted manually.
34bb43b34fb59d9d774ba6785bc9b360ISS Security Advisory - A format string vulnerability has been found in the tooltalk service (rpc.ttdbserverd) on multiple versions of HP-UX, IBM AIX, IRIX, DG-UX, and Solaris. ToolTalk contains a "syslog()" call that will interpret user-supplied formatting arguments. This call is insecure and allows remote attackers to control formatting and manipulate data at arbitrary locations in the memory of the running executable.
fc846f2aab901cd94774643b4e146f2dISS Security Advisory - A buffer overflow has been discovered in the line printer daemon of several BSD implementations. (in.lpd or lpd) A remote or local attacker can execute arbitrary code as root. The vulnerability presents itself when an attacker submits a specially crafted print job and then requests a display of the printer queue to trigger the overflow. Affected versions include OpenBSD CURRENT and earlier, FreeBSD 4.3 and earlier, NetBSD 1.5.1 and earlier, and BSD/OS 4.1 and earlier.
ffba09ec65000c193f64aff77c28366bISS Security Advisory - A buffer overflow has been discovered in the HP-UX line printer daemon (rlpdaemon) which allows a remote or local attacker to execute arbitrary code with superuser privilege. Affected versions include HP-UX 10.01, 10.10, 10.20, 11.00, and 11.11. Rlpdaemon is configured to run by default even if it is not being used.
225386c3d3c624544ff8d532276ffa41ISS Security Advisory - X-Force has discovered buffer overflow vulnerabilities in two popular Remote Authentication Dial-In User Server (RADIUS) implementations. The vulnerabilities in this advisory allow attackers to launch Denial of Service (DoS) attacks against critical network components, bypass 802.11 WLAN access control, and compromise and control protected network resources. Affected versions include Merit 3.6b RADIUS and Lucent 2.1-2 RADIUS. Prior releases are also vulnerable.
5b49d5a5bf26d13e0f3c41583fb17e54ISS Security Alert - A flaw exists in Microsoft Internet Information Server (IIS) that may allow remote attackers to view directory structures, view and delete files, execute arbitrary commands, and deny service to the server. It is possible for attackers to craft URLs that take advantage of a flaw in IIS URL decoding routines. Security mechanisms within these routines can be bypassed. All recent versions of IIS are affected by this vulnerability.
501e29ead39aba3b7ed1aa3339dda9e0ISS Security Advisory - A buffer overflow has been discovered in IRIX rpc.espd, which is installed by default on all current SGI IRIX installations. Remote attackers without accounts can execute commands as root. Patch available here.
