Alpine: multiple wpa_supplicant packages: security update to 2.4-r0 (deprecated)

high Tenable Cloud Security Plugin ID 401150

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- The EAP-pwd peer implementation in hostapd and wpa_supplicant 1.0 through 2.4 does not clear the L
(Length) and M (More) flags before determining if a response should be fragmented, which allows remote
attackers to cause a denial of service (crash) via a crafted message. (CVE-2015-4146)

- The WPS UPnP function in hostapd, when using WPS AP, and wpa_supplicant, when using WPS external registrar
(ER), 0.7.0 through 2.4 allows remote attackers to cause a denial of service (crash) via a negative chunk
length, which triggers an out-of-bounds read or heap-based buffer overflow. (CVE-2015-4141)

- 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. (CVE-2015-4142)

- The EAP-pwd server and peer implementation in hostapd and wpa_supplicant 1.0 through 2.4 allows remote
attackers to cause a denial of service (out-of-bounds read and crash) via a crafted (1) Commit or (2)
Confirm message payload. (CVE-2015-4143)

- The EAP-pwd server and peer implementation in hostapd and wpa_supplicant 1.0 through 2.4 does not validate
that a message is long enough to contain the Total-Length field, which allows remote attackers to cause a
denial of service (crash) via a crafted message. (CVE-2015-4144)
