An issue was discovered in uIP 1.0, as used in Contiki 3.0 and other products. When the Urgent flag is set in a TCP packet, and the stack is configured to ignore the urgent data, the stack attempts to use the value of the Urgent pointer bytes to separate the Urgent data from the normal data, by calculating the offset at which the normal data should be present in the global buffer. However, the length of this offset is not checked; therefore, for large values of the Urgent pointer bytes, the data pointer can point to memory that is way beyond the data buffer in uip_process in uip.c. Se detectó un problema en uIP versión 1.0, como es usado en Contiki versión 3.0 y otros productos. Cuando el flag Urgent es ajustado en un paquete TCP, y la pila está configurada para ignorar los datos urgentes, la pila intenta usar el valor de los bytes del puntero Urgent para separar los datos Urgent de los datos normales, al calcular el desplazamiento en el que los datos normales deben estar presentes en el búfer global. • https://cert-portal.siemens.com/productcert/pdf/ssa-541018.pdf https://us-cert.cisa.gov/ics/advisories/icsa-20-343-01 https://www.kb.cert.org/vuls/id/815128 • CWE-787: Out-of-bounds Write •

An issue was discovered in Contiki through 3.0. An Out-of-Bounds Read vulnerability exists in the uIP TCP/IP Stack component when calculating the checksums for IP packets in upper_layer_chksum in net/ipv4/uip.c. Se detectó un problema en Contiki versiones hasta 3.0. Se presenta una vulnerabilidad de Lectura Fuera de Límites en el componente uIP TCP/IP Stack cuando se calculan las sumas de comprobación para paquetes IP en la función upper_layer_chksum en el archivo net/ipv4/uip.c • https://cert-portal.siemens.com/productcert/pdf/ssa-541018.pdf https://us-cert.cisa.gov/ics/advisories/icsa-20-343-01 https://www.kb.cert.org/vuls/id/815128 • CWE-125: Out-of-bounds Read •

An issue was discovered in Open-iSCSI through 2.0.875. A local attacker can cause the iscsiuio server to abort or potentially execute code by sending messages with incorrect lengths, which (due to lack of checking) can lead to buffer overflows, and result in aborts (with overflow checking enabled) or code execution. The process_iscsid_broadcast function in iscsiuio/src/unix/iscsid_ipc.c does not validate the payload length before a write operation. Se ha descubierto un problema en versiones hasta la 2.0.875 de Open-iSCSI. Un atacante local puede provocar que el servidor iscsiuio se interrumpa o, posiblemente, ejecute código mediante el envío de mensajes con longitudes incorrectas. • http://www.openwall.com/lists/oss-security/2017/12/13/2 https://bugzilla.opensuse.org/show_bug.cgi?id=1072312 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
