Description Quality Assurance univentionstaff 2019-12-11 09:59:00 CET
New Debian git 1:2.11.0-3+deb9u5 fixes:
This update addresses the following issues:
* Arbitrary path overwriting via export-marks command option (CVE-2019-1348)
* recursive submodule cloning allows using git directory twice with  synonymous directory name written in .git/ (CVE-2019-1349)
* Files inside the .git directory may be overwritten during cloning via NTFS  Alternate Data Streams (CVE-2019-1352)
* NTFS protections inactive when running Git in the Windows Subsystem for  Linux (CVE-2019-1353)
* remote code execution in recursive clones (CVE-2019-1387)

+  * Apply patches addressing the security issues CVE-2019-1348,
+    CVE-2019-1349, CVE-2019-1352, CVE-2019-1353, and CVE-2019-1387.
+
+    Credit for finding these vulnerabilities goes to Microsoft
+    Security Response Center, in particular to Nicolas Joly. Fixes
+    were provided by Jeff King and Johannes Schindelin with help
+    from Garima Singh.
+
+  * Reject setting "update = !command" in .gitmodules. This makes
+    the behavior better match Git 2.24.1 which made the same change
+    to address the arbitrary code execution issue CVE-2019-19604
+    (which does not affect Git versions before 2.20.0).
+
+    Also reject "update = !command" in fsck. This ensures that if
+    Git is run as a server with "transfer.fsckObjects" enabled,
+    it cannot be used to attack clients vulnerable to
+    CVE-2019-19604.
+
+    Credit for finding this vulnerability goes to Joern
+    Schneeweisz from GitLab.
