- --------------------------BEGIN INCLUDED TEXT--------------------
Package : git
Version : 1:2.1.4-2.1+deb8u8
CVE ID : CVE-2019-1348 CVE-2019-1349 CVE-2019-1352 CVE-2019-1353=20
CVE-2019-1387
Several vulnerabilities have been discovered in git, a fast, scalable,
distributed revision control system.
CVE-2019-1348
It was reported that the --export-marks option of git fast-import is
exposed also via the in-stream command feature export-marks=3D...,
allowing to overwrite arbitrary paths.
CVE-2019-1387
It was discovered that submodule names are not validated strictly
enough, allowing very targeted attacks via remote code execution
when performing recursive clones.
In addition this update addresses a number of security issues which are
only an issue if git is operating on an NTFS filesystem (CVE-2019-1349,
CVE-2019-1352 and CVE-2019-1353).
For Debian 8 "Jessie", these problems have been fixed in version
1:2.1.4-2.1+deb8u8.
We recommend that you upgrade your git packages.
