Die Firma Cisco hat neue Versionen des freien Antivirenpakets ClamAV 1.0.1, 0.105.3 und 0.103.8 ver\u00f6ffentlicht, die eine kritische Vulnerabilit\u00e4t (CVE-2023-20032) beheben, die zu einer Codeausf\u00fchrung beim Scannen von ClamAV-Dateien mit speziell gestalteten HFS+-Image-Dateien f\u00fchren kann. <\/p>\n

Die Schwachstelle entsteht durch unzureichende \u00dcberpr\u00fcfung der Puffergr\u00f6\u00dfe, was es erm\u00f6glicht, Daten au\u00dferhalb des Puffers zu schreiben und die Ausf\u00fchrung von Code mit den Rechten des ClamAV-Prozesses zu erm\u00f6glichen, beispielsweise beim Scannen von Dateien auf einem Mailserver, die aus E-Mails extrahiert werden. Die Ver\u00f6ffentlichung von Paketupdates in den Distributionen kann auf den Seiten nachverfolgt werden: Debian, Ubuntu, Gentoo, RHEL, SUSE, Arch, FreeBSD, NetBSD. <\/p>\n

In den neuen Versionen wurde auch eine weitere Schwachstelle (CVE-2023-20052) behoben, die zu einer m\u00f6glichen Offenlegung von Inhalten aus beliebigen Dateien f\u00fchren kann, Server<\/a>, auf die der Prozess, der das Scannen durchf\u00fchrt, Zugriff hat. Die Schwachstelle tritt beim Parsen speziell gestalteter DMG-Dateien auf und entsteht dadurch, dass der Parser beim Parsing externe XML-Elemente zul\u00e4sst, auf die in der zu parsenden DMG-Datei verwiesen wird.
