Date Reported:
10 Jul 2019
Affected Packages:
Security database references:
In Mitre's CVE dictionary: CVE-2019-9948.
More information:

The urllib library in Python ships support for a second, not well known URL scheme for accessing local files ("local_file://"). This scheme can be used to circumvent protections that try to block local file access and only block the well-known "file://" schema. This update addresses the vulnerability by disallowing the "local_file://" URL scheme.

This update also fixes another regresssion introduced in the update issued as DLA-1835-1 that broke installation of libpython3.4-testsuite.

For Debian 8 Jessie, this problem has been fixed in version 3.4.2-1+deb8u5.

We recommend that you upgrade your python3.4 packages.
