Alpine: multiple vlc packages: security update to 3.0.9.2-r0

critical Tenable Cloud Security Plugin ID 407539

Description

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

- 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 off-by-one error in the DecodeBlock function in codec/sdl_image.c in VideoLAN VLC media player before
3.0.9 allows remote attackers to cause a denial of service (memory corruption) via a crafted image file.
NOTE: this may be related to the SDL_Image product. (CVE-2019-19721)

- 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 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)
