Flash Player < 26.0.0.126 Multiple RCE (APSB17-17)

High

Synopsis

The remote host is running an outdated version of Adobe Flash Player that is affected by multiple Remote Code Execution (RCE) attack vectors.

Description

Versions of Adobe Flash Player prior to 26.0.0.126 are unpatched, and therefore affected by the following RCE vulnerabilities :

- A use-after-free error exists in the XML Load method. The issue is triggered when handling XML objects. With a specially crafted file, a context-dependent attacker can dereference already freed memory and potentially execute arbitrary code. (CVE-2017-3075) - A flaw exists that is triggered as certain input is not properly validated. This may allow a context-dependent attacker to corrupt memory and cause a denial of service or potentially execute arbitrary code. (CVE-2017-3076, CVE-2017-3077, CVE-2017-3078, CVE-2017-3079) - A use-after-free error exists that may allow a context-dependent attacker to dereference already freed memory and potentially execute arbitrary code. No further details have been provided. (CVE-2017-3081) - A flaw exists that is triggered as LocaleID determinePreferredLocales metadata objects are not properly validated. This may allow a context-dependent attacker to corrupt memory and cause a denial of service or potentially execute arbitrary code. (CVE-2017-3082) - A use-after-free error exists during profile object handling. With a specially crafted file, a context-dependent attacker can dereference already freed memory and potentially execute arbitrary code. (CVE-2017-3083) - A use-after-free error exists during the cloning of AuditudeSettings objects. With a specially crafted file, a context-dependent attacker can dereference already freed memory and potentially execute arbitrary code. (CVE-2017-3084)

Solution

Upgrade to Adobe Flash Player version 26.0.0.126 or later.
