CVE-2017-5029 – chromium-browser: integer overflow in libxslt

https://notcve.org/view.php?id=CVE-2017-5029

The xsltAddTextString function in transform.c in libxslt 1.1.29, as used in Blink in Google Chrome prior to 57.0.2987.98 for Mac, Windows, and Linux and 57.0.2987.108 for Android, lacked a check for integer overflow during a size calculation, which allowed a remote attacker to perform an out of bounds memory write via a crafted HTML page. La función xsltAddTextString en transform.c en libxslt 1.1.29, tal como se utiliza en Blink en Google Chrome anteriores a 57.0.2987.98 para Mac, Windows y Linux y 57.0.2987.108 para Android, carecía de una comprobación de desbordamiento de entero durante un cálculo de tamaño, lo que permite a un atacante remoto realizar una escritura de memoria fuera de límites a través de una página HTML diseñada. • http://rhn.redhat.com/errata/RHSA-2017-0499.html http://www.debian.org/security/2017/dsa-3810 http://www.securityfocus.com/bid/96767 http://www.securitytracker.com/id/1038157 https://chromereleases.googleblog.com/2017/03/stable-channel-update-for-desktop.html https://crbug.com/676623 https://git.gnome.org/browse/libxslt/commit/?id=08ab2774b870de1c7b5a48693df75e8154addae5 https://access.redhat.com/security/cve/CVE-2017-5029 https://bugzilla.redhat.com/show_bug.cgi?id=1431033 • CWE-787: Out-of-bounds Write •
