NVD Description

Note: Versions mentioned in the description apply only to the upstream opendkim package and not the opendkim package as distributed by Debian. See How to fix? for Debian:12 relevant fixed versions and status.

The test suite in libopendkim in OpenDKIM through 2.10.3 allows local users to gain privileges via a symlink attack against the /tmp/testkeys file (related to t-testdata.h, t-setup.c, and t-cleanup.c). NOTE: this is applicable to persons who choose to engage in the "A number of self-test programs are included here for unit-testing the library" situation.
