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
Several vulnerabilities have been discovered in git, a fast, scalable,
distributed revision control system.
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.
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
We recommend that you upgrade your git packages.
