Synopsis
A vulnerability has been discovered in dpkg, which allows for directory
traversal.
Background
Debian package management system.
Affected Packages
Package Vulnerable Unaffected
------------- ------------ ------------
app-arch/dpkg < 1.20.9-r1 >= 1.20.9-r1
Impact
Dpkg::Source::Archive in dpkg, the Debian package management system, is
prone to a directory traversal vulnerability. When extracting untrusted
source packages in v2 and v3 source package formats that include a
debian.tar, the in-place extraction can lead to directory traversal
situations on specially crafted orig.tar and debian.tar tarballs.
Workaround
There is no known workaround at this time.
