      Findings from https://issues.redhat.com/browse/RHEL-22390:

      Error: UNINIT (CWE-457):
      rpm-4.16.1.3/lib/rpmts.c:478: var_decl: Declaring variable "kd" without initializer.
      rpm-4.16.1.3/lib/rpmts.c:537: uninit_use_in_call: Using uninitialized value "kd.signid" when calling "finiPgpData".
      rpm-4.16.1.3/lib/rpmts.c:537: uninit_use_in_call: Using uninitialized value "kd.timestr" when calling "finiPgpData".
      rpm-4.16.1.3/lib/rpmts.c:537: uninit_use_in_call: Using uninitialized value "kd.verid" when calling "finiPgpData".

      1. 535| headerFree(h);
      2. 536| pgpFreeDig(dig);
      3. 537|-> finiPgpData(&kd);
      4. 538| free(enc);
      5. 539| free(d);

       

      In the unlikely case that base64 encoding of a pubkey data fails, the code will try to free uninitialized pointers.
