Package : git
CVE ID : CVE-2019-1348 CVE-2019-1349 CVE-2019-1352 CVE-2019-1353
CVE-2019-1387 CVE-2019-19604
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).
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.
