Descriptions

Integer underflow in the ieee80211_rx function in net/ieee80211/ieee80211_rx.c in the Linux kernel 2.6.x before 2.6.23 allows remote attackers to cause a denial of service (crash) via a crafted SKB length value in a runt IEEE 802.11 frame when the IEEE80211_STYPE_QOS_DATA flag is set, aka an "off-by-two error."

desbordamiento inferior de entero en la funcióni eee80211_rx en net/ieee80211/ieee80211_rx.c en el nucleo de Linux 2.6.x anterior a 2.6.23 permite a atacantes remotos provocar denegación de servicio (caida) a través de una longitud SKB manipulada en una ventana pequeña IEEE 802.11 cuando la bandera IEEE80211_STYPE_QOS_DATA está asignada, también conocido como "error de duera de los dos"

Some vulnerabilities were discovered and corrected in the Linux 2.6 kernel. The minix filesystem code allows local users to cause a denial of service (hang) via a malformed minix file stream. An integer underflow in the Linux kernel prior to 2.6.23 allows remote attackers to cause a denial of service (crash) via a crafted SKB length value in a runt IEEE 802.11 frame when the IEEE80211_STYPE_QOS_DATA flag is set.
