Sono state rivelate due vulnerabilit\u00e0 nel pacchetto per ufficio open source LibreOffice, la pi\u00f9 pericolosa delle quali potrebbe consentire l'esecuzione di codice aprendo un documento appositamente progettato. La prima vulnerabilit\u00e0 \u00e8 stata corretta senza troppe pubblicit\u00e0 nei rilascio di marzo 7.4.6 e 7.5.1, mentre la seconda \u00e8 stata sistemata negli aggiornamenti di maggio di LibreOffice 7.4.7 e 7.5.3. <\/p>\n

La prima vulnerabilit\u00e0 (CVE-2023-0950) potrebbe consentire l'esecuzione di codice nella sistema aprendo un foglio di calcolo che include formule appositamente modificate, come AGGREGATE, nelle quali sono stati forniti meno parametri di quelli previsti. Il problema \u00e8 causato da un overflow dell'indice dell'array attraverso il limite inferiore (underflow) nel codice di analisi delle formule (ScInterpreter) utilizzato nell'elaborazione dei fogli di calcolo. <\/p>\n

La seconda vulnerabilit\u00e0 (CVE-2023-2255) consente a un attaccante di preparare un documento appositamente formattato, il quale, una volta aperto, carica collegamenti esterni senza visualizzare alcuna richiesta di autorizzazione o avviso, contrariamente al comportamento dichiarato di LibreOffice, che prevede la visualizzazione di un avviso prima di caricare contenuti correlati. Il problema \u00e8 causato da una lacuna nel codice di richiesta di autorizzazione quando si utilizza il meccanismo dei «Floating Frames», simile agli iframe in HTML, che consente di includere dinamicamente contenuti di file esterni nel documento.
