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=..., 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
1:2.1.4-2.1+deb8u8.
We recommend that you upgrade your git packages.
