More information:

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=..., 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.
