Description Quality Assurance univentionstaff 2018-12-06 16:31:35 CET
New Debian nsis 2.46-10+deb8u1 fixes:
This update addresses the following issues:
* Nullsoft Scriptable Install System (NSIS) before 2.49 uses temporary folder  locations that allow unprivileged local users to overwrite files. This  allows a local attack in which either a plugin or the uninstaller can be  replaced by a Trojan horse program. (CVE-2015-9267)
* Nullsoft Scriptable Install System (NSIS) before 2.49 has unsafe implicit  linking against Version.dll. In other words, there is no protection  mechanism in which a wrapper function resolves the dependency at an  appropriate time during runtime. (CVE-2015-9268)

+  * Non-maintainer upload by the LTS Team. 
+  * CVE-2015-9267, CVE-2015-9268
+    Fix for several issues:
+      - use SetDefaultDllDirectories() to restrict implicitly loaded
+        and dynamically loaded modules from trusted directories
+      - create temporary directory in a way that only elevated users
+        can write into it
+      - no implicit linking against Version.dll but use of wrapper
+        functions

   * Fail the build if libwinpthread is needed at runtime (see #722898)
