Detail

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.

CVE-2019-19604

Joern Schneeweisz reported a vulnerability, where a recursive clone followed by a submodule update could execute code contained within the repository without the user explicitly having asked for that. It is now disallowed for `.gitmodules` to have entries that set `submodule..update=!command`.

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 the oldstable distribution (stretch), these problems have been fixed in version 1:2.11.0-3+deb9u5.

For the stable distribution (buster), these problems have been fixed in version 1:2.20.1-2+deb10u1.

We recommend that you upgrade your git packages.
