Questa vulnerabilit\u00e0 consente a un utente locale di elevare i propri privilegi di sistema mediante l'impostazione di dati opportunamente formattati nella variabile d'ambiente GLIBC_TUNABLES prima di eseguire un file eseguibile con il flag suid root, ad esempio, \/usr\/bin\/su.    <\/p>\n<p>\u00c8 stata dimostrata la possibilit\u00e0 di sfruttare con successo la vulnerabilit\u00e0 su Fedora 37 e 38, Ubuntu 22.04 e 23.04, Debian 12 e 13. Si presume che la vulnerabilit\u00e0 possa manifestarsi anche su altre distribuzioni che utilizzano Glibc. Le distribuzioni basate sulla libreria di sistema Musl, come Alpine Linux, non sono vulnerabili. La vulnerabilit\u00e0 \u00e8 stata corretta con un patch rilasciato il 2 ottobre. \u00c8 possibile monitorare il rilascio di aggiornamenti delle librerie sulle pagine di Debian, Ubuntu, RHEL, SUSE\/openSUSE, Fedora, Arch, Gentoo, ALT Linux.    <\/p>\n<p>La vulnerabilit\u00e0 \u00e8 causata da una modifica apportata nell'aprile 2021 e inclusa nella versione glibc 2.34. A causa di un errore nel codice di parsing della stringa specificata nella variabile d'ambiente GLIBC_TUNABLES, una combinazione errata di parametri in questa variabile porta alla scrittura del valore analizzato al di fuori del buffer allocato. Il problema si manifesta quando, invece delle normali sequenze \u00abname=val\u00bb, i parametri sono forniti nella forma di doppia assegnazione \u00abname=name=val\u00bb. In questo caso, l'assegnazione viene elaborata due volte, prima come \u00abname=name=val\u00bb, poi come \u00abname=val\u00bb. Questa doppia elaborazione genera un risultato \u00abname=name=val:name=val\u00bb, la cui dimensione supera quella del buffer tunestr.      <\/p>\n<p>\u0418\u0441\u0441\u043b\u0435\u0434\u043e\u0432\u0430\u0442\u0435\u043b\u044f\u043c\u0438 \u043f\u043e\u0434\u0433\u043e\u0442\u043e\u0432\u043b\u0435\u043d \u0441\u0442\u0430\u0431\u0438\u043b\u044c\u043d\u043e \u0440\u0430\u0431\u043e\u0442\u0430\u044e\u0449\u0438\u0439 \u044d\u043a\u0441\u043f\u043b\u043e\u0438\u0442, \u043a\u043e\u0442\u043e\u0440\u044b\u0439 \u043f\u043e\u0437\u0432\u043e\u043b\u044f\u0435\u0442 \u043f\u043e\u043b\u0443\u0447\u0438\u0442\u044c \u043f\u0440\u0430\u0432\u0430 root \u043f\u0440\u0438 \u043f\u0440\u0438\u043c\u0435\u043d\u0435\u043d\u0438\u0438 \u043f\u0440\u0430\u043a\u0442\u0438\u0447\u0435\u0441\u043a\u0438 \u0441 \u043b\u044e\u0431\u043e\u0439 \u043f\u0440\u043e\u0433\u0440\u0430\u043c\u043c\u043e\u0439 \u0441 \u0444\u043b\u0430\u0433\u043e\u043c suid root. \u0418\u0441\u043a\u043b\u044e\u0447\u0435\u043d\u0438\u0435 \u0441\u043e\u0441\u0442\u0430\u0432\u043b\u044f\u044e\u0442 \u0443\u0442\u0438\u043b\u0438\u0442\u0430 sudo (\u043c\u0435\u043d\u044f\u0435\u0442 \u0437\u043d\u0430\u0447\u0435\u043d\u0438\u0435 ELF RUNPATH), \u0443\u0442\u0438\u043b\u0438\u0442\u044b  chage \u0438 passwd \u0432 Fedora (\u0437\u0430\u0449\u0438\u0449\u0435\u043d\u044b \u043e\u0442\u0434\u0435\u043b\u044c\u043d\u044b\u043c\u0438 \u043f\u0440\u0430\u0432\u0438\u043b\u0430\u043c\u0438 SELinux) \u0438 \u0443\u0442\u0438\u043b\u0438\u0442\u0430 snap-confine \u0432 Ubuntu (\u0437\u0430\u0449\u0438\u0449\u0435\u043d\u0430 \u043e\u0442\u0434\u0435\u043b\u044c\u043d\u044b\u043c\u0438 \u043f\u0440\u0430\u0432\u0438\u043b\u0430\u043c\u0438 AppArmor). \u041f\u0440\u0435\u0434\u043b\u043e\u0436\u0435\u043d\u043d\u044b\u0439 \u043c\u0435\u0442\u043e\u0434 \u044d\u043a\u0441\u043f\u043b\u0443\u0430\u0442\u0430\u0446\u0438\u0438 \u0442\u0430\u043a\u0436\u0435 \u043d\u0435 \u0440\u0430\u0431\u043e\u0442\u0430\u0435\u0442 \u0432 RHEL 8 \u0438 RHEL 9, \u0445\u043e\u0442\u044f \u0434\u0430\u043d\u043d\u044b\u0435 \u0432\u0435\u0442\u043a\u0438 \u0438 \u043f\u043e\u0434\u0432\u0435\u0440\u0436\u0435\u043d\u044b \u0443\u044f\u0437\u0432\u0438\u043c\u043e\u0441\u0442\u0438 (\u0434\u043b\u044f \u0430\u0442\u0430\u043a\u0438 \u0442\u0440\u0435\u0431\u0443\u0435\u0442\u0441\u044f \u0441\u043e\u0437\u0434\u0430\u043d\u0438\u0435 \u0438\u043d\u043e\u0433\u043e \u044d\u043a\u0441\u043f\u043b\u043e\u0438\u0442\u0430).  \u041a\u043e\u0434 \u044d\u043a\u0441\u043f\u043b\u043e\u0438\u0442\u0430 \u0431\u0443\u0434\u0435\u0442 \u043e\u043f\u0443\u0431\u043b\u0438\u043a\u043e\u0432\u0430\u043d \u043f\u043e\u0437\u0434\u043d\u0435\u0435 \u043f\u043e\u0441\u043b\u0435 \u043f\u043e\u0432\u0441\u0435\u043c\u0435\u0441\u0442\u043d\u043e\u0433\u043e \u0443\u0441\u0442\u0440\u0430\u043d\u0435\u043d\u0438\u044f \u0443\u044f\u0437\u0432\u0438\u043c\u043e\u0441\u0442\u0438. \u041f\u0440\u043e\u0432\u0435\u0440\u0438\u0442\u044c \u043f\u043e\u0434\u0432\u0435\u0440\u0436\u0435\u043d\u043d\u043e\u0441\u0442\u044c \u0441\u0432\u043e\u0435\u0439 \u0441\u0438\u0441\u0442\u0435\u043c\u044b \u0443\u044f\u0437\u0432\u0438\u043c\u043e\u0441\u0442\u0438 \u043c\u043e\u0436\u043d\u043e \u043d\u0438\u0436\u0435 \u0443\u043a\u0430\u0437\u0430\u043d\u043d\u043e\u0439 \u043a\u043e\u043c\u0430\u043d\u0434\u043e\u0439, \u043a\u043e\u0442\u043e\u0440\u0430\u044f \u0432 \u0441\u043b\u0443\u0447\u0430\u0435 \u043d\u0430\u043b\u0438\u0447\u0438\u044f \u043f\u0440\u043e\u0431\u043b\u0435\u043c\u044b \u0437\u0430\u0432\u0435\u0440\u0448\u0438\u0442\u044c\u0441\u044f \u043a\u0440\u0430\u0445\u043e\u043c:         env -i &#171;GLIBC_TUNABLES=glibc.malloc.mxfast=glibc.malloc.mxfast=A&#187; &#171;Z=`printf &#8216;%08192x&#8217; 1`&#187; \/usr\/bin\/su &#8212;help      <\/p>\n<p>Viene inoltre segnalata la correzione di altre due vulnerabilit\u00e0 in Glibc:  <\/p>\n<ul>\n<li class=\"l\"> CVE-2023-4806 \u2014 accesso a una memoria gi\u00e0 liberata (use-after-free) nella funzione getaddrinfo(), che si manifesta quando il plugin NSS implementa solo le chiamate di callback \u00ab_gethostbyname2_r\u00bb e \u00ab_getcanonname_r\u00bb, ma non supporta la chiamata \u00ab_gethostbyname3_r\u00bb.
