Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-2728 advisory.

It was discovered that there were a number of issues in VideoLAN (aka 'vlc', a popular video and multimedia player: CVE-2021-25801 A buffer overflow vulnerability in the __Parse_indx component allowed attackers to cause an out-of-bounds read via a crafted .avi file. CVE-2021-25802 A buffer overflow vulnerability in the AVI_ExtractSubtitle component could have allowed attackers to cause an out-of-bounds read via a crafted .avi file. CVE-2021-25803 A buffer overflow vulnerability in the vlc_input_attachment_New component allowed attackers to cause an out-of-bounds read via a specially- crafted .avi file. CVE-2021-25804 A NULL-pointer dereference in Open in avi.c can result in a denial of service (DoS) vulnerability. For Debian 9 Stretch, these problems have been fixed in version 3.0.11-0+deb9u2. We recommend that you upgrade your vlc packages.
