Debian DSA-4581-1 : git - security update

critical Nessus Plugin ID 131966

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

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.<name>.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 ).

Solution

Upgrade the git packages.

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.
