CVE-2017-10708 (CCN-129518)

Assigned:2017-06-26
Published:2017-06-26
Updated:2017-08-07
Summary:An issue was discovered in Apport through 2.20.x. In apport/report.py, Apport sets the ExecutablePath field and it then uses the path to run package specific hooks without protecting against path traversal. This allows remote attackers to execute arbitrary code via a crafted .crash file.
