Vulnerabilidades

The Smc.exe process in My Firewall Plus 5.0 build 1117, and possibly other versions, does not drop privileges before invoking help, which allows local users to gain privileges.

Memory leak in passwd 0.68 allows local users to cause a denial of service (memory consumption) via a large number of failed read attempts from the password buffer.

Off-by-one error in passwd 0.68 and earlier, when using the --stdin option, causes passwd to use the first 78 characters of a password instead of the first 79, which results in a small reduction of the search space required for brute force attacks.

Check Point Firewall-1 4.1 up to NG AI R55 allows remote attackers to obtain potentially sensitive information by sending an Internet Key Exchange (IKE) with a certain Vendor ID payload that causes Firewall-1 to return a response containing version and other information.

Multiple interpretation error in various F-Secure Anti-Virus products, including Workstation 5.43 and earlier, Windows Servers 5.50 and earlier, MIMEsweeper 5.50 and earlier, Anti-Virus for Linux Servers and Gateways 4.61 and earlier, and other products, allows remote attackers to bypass antivirus protection via a…

Symantec Enterprise Firewall/VPN Appliances 100, 200, and 200R running firmware before 1.63 and Gateway Security 320, 360, and 360R running firmware before 622 allow remote attackers to bypass filtering and determine whether the device is running services such as tftpd, snmpd, or isakmp via a UDP port scan with a…

Buffer overflow in Entrust LibKmp ISAKMP library, as used by Symantec Enterprise Firewall 7.0 through 8.0, Gateway Security 5300 1.0, Gateway Security 5400 2.0, and VelociRaptor 1.5, allows remote attackers to execute arbitrary code via a crafted ISAKMP payload.

Kerio WinRoute Firewall before 6.0.9 uses information from PTR queries in response to A queries, which allows remote attackers to poison the DNS cache or cause a denial of service (connection loss).

Symantec Enterprise Firewall/VPN Appliances 100, 200, and 200R running firmware before 1.63 allow remote attackers to cause a denial of service (device freeze) via a fast UDP port scan on the WAN interface.

Symantec Enterprise Firewall/VPN Appliances 100, 200, and 200R running firmware before 1.63 and Gateway Security 320, 360, and 360R running firmware before 622 uses a default read/write SNMP community string, which allows remote attackers to alter the firewall's configuration file.

The Web Filtering functionality in Kerio Personal Firewall (KPF) 4.0.13 allows remote attackers to cause a denial of service (crash) by sending hex-encoded URLs containing "%13%12%13".

The H.323 protocol agent in StoneSoft firewall engine 2.2.8 and earlier allows remote attackers to cause a denial of service (crash) via crafted H.323 packets.

Buffer overflow in multiple F-Secure Anti-Virus products, including F-Secure Anti-Virus 5.42 and earlier, allows remote attackers to bypass scanning or cause a denial of service (crash or module restart), depending on the product, via a malformed LHA archive.

Kerio Personal Firewall (KPF) 2.1.5 allows local users to execute arbitrary code with SYSTEM privileges via the Load button in the Firewall Configuration Files option, which does not drop privileges before opening the file loading dialog box.

Novell Client Firewall (NCF) 2.0, as based on the Agnitum Outpost Firewall, allows local users to execute arbitrary code with SYSTEM privileges by opening the NCF tray icon and using the Help functionality to launch programs with SYSTEM privileges.

Agnitum Outpost Pro Firewall 2.1 allows remote attackers to cause a denial of service (CPU consumption) via a flood of small, invalid packets, which can not be processed quickly enough by Outpost Pro.

Vulnerabilidad de cadena de formato en Speedtouch USB driver anteriores a 1.3.1 permite a usuarios locales ejecutar código de su elección mediante modem_run pppoa2, o pppoa3

Multiples vulnerabilidades desconocidas en el kernel 2.6 de Linux permite a usuarios locales ganar privilegios o acceder a memoria del kernel, un grupo de vulerabilidades distinto de los identificado por CAN-2004-0495, como se ha encontrado con la herramienta de comprobación de código fuente Sparse

Vulnerabilidad desconocida en el kernel 2.x de Linux puede permitir a usuarios locales modificar el ID de grupo de ficheros, como ficheros exportados con NFS en kernel 2.4.

Fuga de información de punto flotante en el código de cambio de contexto de Linux 2.4.x sólo comprueba el bit MFH pero no verifica el propietario de FPH, lo que permite a usuarios locales leer valores de registros de otros procesos estableciendo el bit MFH.

El código que une SSL/TLS en OpenSSL 0.9.7a, 0.9.7b y 0.9.7c, usando Kerberos, no comprueba adecuadamente la longitud de los tickets de Kerberos, lo que permite que atacantes remotos provoquen una denegación de servicio.

La función do_change_cipher_spec en OpenSSL 0.9.6c hasta 0.9.6.k y 0.9.7a hasta 0.9.7c permite que atacantes remotos provoquen una denegación de servicio (caída) mediante una hábil unión SSL/TLS que provoca un puntero nulo.

OpenSSL 0.9.6 anteriores a la 0.9.6d no manejan adecuadamente los tipos de mensajes desconocidos, lo que permite a atacantes remotos causar una denegación de servicios (por bucle infinito), como se demuestra utilizando la herramienta de testeo Codenomicon TLS.

Desbordamiento de búfer basado en el montón en la librería de decodificación ASN.1 de productos CheckPoint VPN-1, cuando se ha implementado IKE agresivo, permite a atacantes remotos ejecutar código de su elección iniciando una negociación IKE y enviando un paquete IKE con datos ASN.1 malformados.

Kerio Personal Firewall 4.0 (KPF4) allows local users with administrative privileges to bypass the Application Security feature and execute arbitrary processes by directly writing to \device\physicalmemory to restore the running kernel's SDT ServiceTable.
