Cisco ha pubblicato nuove versioni del pacchetto antivirus open source ClamAV 1.0.1, 0.105.3 e 0.103.8, che risolvono una vulnerabilit\u00e0 critica (CVE-2023-20032) in grado di consentire l'esecuzione di codice durante la scansione di file in ClamAV con immagini disco appositamente formattate in HFS+. <\/p>\n

La vulnerabilit\u00e0 \u00e8 causata dalla mancanza di un'adeguata verifica delle dimensioni del buffer, che permette di scrivere dati oltre i limiti del buffer ed eseguire codice con i privilegi del processo ClamAV, ad esempio, quando scansiona file estratti da email su un server di posta. Gli aggiornamenti dei pacchetti nei vari distribuzioni possono essere seguiti nelle pagine: Debian, Ubuntu, Gentoo, RHEL, SUSE, Arch, FreeBSD, NetBSD. <\/p>\n

Nei nuovi rilasci \u00e8 stata corretta anche un'altra vulnerabilit\u00e0 (CVE-2023-20052), che potrebbe portare a perdite di contenuto da qualsiasi file accessibile al processo che sta eseguendo la scansione. server<\/a>La vulnerabilit\u00e0 si manifesta durante l'analisi di file formattati appositamente in DMG ed \u00e8 causata dal fatto che il parser consente l'inserimento di elementi XML esterni, ai quali si fa riferimento nel DMG in fase di analisi.
