Title:	Debian: Security Advisory (DLA-2246-1)
Summary:	The remote host is missing an update for the Debian 'xawtv' package(s) announced via the DLA-2246-1 advisory.
Description:	Summary: The remote host is missing an update for the Debian 'xawtv' package(s) announced via the DLA-2246-1 advisory. Vulnerability Insight: An issue was discovered in LinuxTV xawtv before 3.107. The function dev_open() in v4l-conf.c does not perform sufficient checks to prevent an unprivileged caller of the program from opening unintended filesystem paths. This allows a local attacker with access to the v4l-conf setuid-root program to test for the existence of arbitrary files and to trigger an open on arbitrary files with mode O_RDWR. To achieve this, relative path components need to be added to the device path, as demonstrated by a v4l-conf -c /dev/../root/.bash_history command. For Debian 8 Jessie, this problem has been fixed in version 3.103-3+deb8u1. We recommend that you upgrade your xawtv packages.

Solution: Please install the updated package(s). CVSS Score: 3.6 CVSS Vector: AV:L/AC:L/Au:N/C:P/I:P/A:N
