Title:	Debian: Security Advisory (DLA-3237-1)
Summary:	The remote host is missing an update for the Debian 'node-tar' package(s) announced via the DLA-3237-1 advisory.
Description:	Summary: The remote host is missing an update for the Debian 'node-tar' package(s) announced via the DLA-3237-1 advisory. Vulnerability Insight: Cache poisoning vulnerabilities were found in node-tar, a Node.js module used to read and write portable tar archives, which may result in arbitrary file creation or overwrite. CVE-2021-37701 It was discovered that node-tar performed insufficient symlink protection, thereby making directory cache vulnerable to poisoning using symbolic links. Upon extracting an archive containing a directory `foo/bar` followed with a symbolic link `foobar` to an arbitrary location, node-tar would extract arbitrary files into the symlink target, thus allowing arbitrary file creation and overwrite. Moreover, on case-insensitive filesystems, a similar issue occurred with a directory `FOO` followed with a symbolic link `foo`. CVE-2021-37712 Similar to CVE-2021-37701, a specially crafted tar archive containing two directories and a symlink with names containing unicode values that normalized to the same value, would bypass node-tar's symlink checks on directories, thus allowing arbitrary file creation and overwrite. For Debian 10 buster, these problems have been fixed in version 4.4.6+ds1-3+deb10u2. We recommend that you upgrade your node-tar packages.
