QDBM is a library of routines for managing a database. ImageMagick is a collection of tools to read, write and manipulate images. GDAL is a geospatial data abstraction library.
Some packages may introduce insecure paths into the list of directories that are searched for libraries at runtime. Furthermore, packages depending on the MakeMaker Perl module for build configuration may have incorrectly copied the LD_RUN_PATH into the DT_RPATH.
A local attacker, who is a member of the "portage" group, could create a malicious shared object in the Portage temporary build directory that would be loaded at runtime by a dependent executable, potentially resulting in privilege escalation.
Only grant "portage" group rights to trusted users.
