Several issues have been found in libvpx, a VP8 and VP9 video codec.

CVE-2019-9232

There is a possible out of bounds read due to a missing bounds check.
This could lead to remote information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation.

CVE-2019-9433

There is a possible information disclosure due to improper input validation. This could lead to remote information disclosure with no additional execution privileges needed. User interaction is needed for exploitation.

For Debian 8 β€˜Jessie’, these problems have been fixed in version 1.3.0-3+deb8u2.

We recommend that you upgrade your libvpx packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
