VLC < 3.0.9 Multiple Vulnerabilities

critical Nessus Plugin ID 136422

Language:

Synopsis

The remote Windows host contains a media player that is affected by multiple vulnerabilities.

Description

The version of VLC media player installed on the remote Windows host is prior to 3.0.9. It is, therefore, affected by multiple vulnerabilities:

 - An exploitable denial-of-service vulnerability exists in the resource record-parsing functionality of Videolabs libmicrodns 0.1.0. When parsing compressed labels in mDNS messages, the compression pointer is followed without checking for recursion, leading to a denial of service. An attacker can send an mDNS message to trigger this vulnerability (CVE-2020-6071).

- An exploitable code execution vulnerability exists in the label-parsing functionality of Videolabs libmicrodns 0.1.0. When parsing compressed labels in mDNS messages, the rr_decode function's return value is not checked, leading to a double free that could be exploited to execute arbitrary code. An attacker can send an mDNS message to trigger this vulnerability (CVE-2020-6072).

 - An exploitable denial-of-service vulnerability exists in the TXT record-parsing functionality of Videolabs libmicrodns 0.1.0. When parsing the RDATA section in a TXT record in mDNS messages, multiple integer overflows can be triggered, leading to a denial of service. An attacker can send an mDNS message to trigger this vulnerability (CVE-2020-6073).

 - An exploitable denial-of-service vulnerability exists in the message-parsing functionality of Videolabs libmicrodns 0.1.0. When parsing mDNS messages, the implementation does not properly keep track of the available data in the message, possibly leading to an out-of-bounds read that would result in a denial of service. An attacker can send an mDNS message to trigger this vulnerability (CVE-2020-6077).

 - An exploitable denial-of-service vulnerability exists in the message-parsing functionality of Videolabs libmicrodns 0.1.0. When parsing mDNS messages in mdns_recv, the return value of the mdns_read_header function is not checked, leading to an uninitialized variable usage that eventually results in a null pointer dereference, leading to service crash. An attacker can send a series of mDNS messages to trigger this vulnerability (CVE-2020-6078).

 - An exploitable denial-of-service vulnerability exists in the resource allocation handling of Videolabs libmicrodns 0.1.0. When encountering errors while parsing mDNS messages, some allocated data is not freed, possibly leading to a denial-of-service condition via resource exhaustion. An attacker can send one mDNS message repeatedly to trigger this vulnerability through decoding of the domain name performed by rr_decode (CVE-2020-6079).

Solution

Upgrade to VLC version 3.0.9 or later.
