CVE-2015-4142 – hostapd: integer underflow in AP mode WMM Action frame processing

https://notcve.org/view.php?id=CVE-2015-4142

Integer underflow in the WMM Action frame parser in hostapd 0.5.5 through 2.4 and wpa_supplicant 0.7.0 through 2.4, when used for AP mode MLME/SME functionality, allows remote attackers to cause a denial of service (crash) via a crafted frame, which triggers an out-of-bounds read. Subdesbordamiento de enteros en el analizador sintáctico Frame de WMM Action en hostapd 0.5.5 hasta 2.4 y wpa_supplicant 0.7.0 hasta 2.4, cuando utilizado para la funcionalidad MLME/SME del modo AP, permite a atacantes remotos causar una denegación de servicio (caída) a través de un Frame manipulado, lo que provoca una lectura fuera de rango. An integer underflow flaw, leading to a buffer over-read, was found in the way wpa_supplicant handled WMM Action frames. A specially crafted frame could possibly allow an attacker within Wi-Fi radio range to cause wpa_supplicant to crash. • http://lists.fedoraproject.org/pipermail/package-announce/2015-November/171401.html http://lists.fedoraproject.org/pipermail/package-announce/2015-November/172608.html http://lists.fedoraproject.org/pipermail/package-announce/2015-November/172655.html http://lists.opensuse.org/opensuse-updates/2015-06/msg00019.html http://rhn.redhat.com/errata/RHSA-2015-1090.html http://rhn.redhat.com/errata/RHSA-2015-1439.html http://seclists.org/fulldisclosure/2022/May/34 http://w1.fi/security/2015-3/integer • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read •
