The remote host is affected by the vulnerability described in GLSA-201101-03 (libvpx: User-assisted execution of arbitrary code)
libvpx is vulnerable to an integer overflow vulnerability when processing crafted VP8 video streams.
Impact :
A remote attacker could entice a user to open a specially crafted media file, possibly resulting in the execution of arbitrary code with the privileges of the user running the application, or a Denial of Service.
Workaround :
There is no known workaround at this time.
