Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Citrix Online Plug-in for Windows for XenApp & XenDesktop before 11.2, Citrix Online Plug-in for Mac for XenApp & XenDesktop before 11.0, Citrix ICA Client for Linux before 11.100, Citrix ICA Client for Solaris before 8.63, and Citrix Receiver for Windows Mobile before 11.5 allow remote attackers to execute arbitrary code via (1) a crafted HTML document, (2) a crafted .ICA file, or (3) a crafted type field in an ICA graphics packet, related to a "heap offset overflow" issue.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

How this class of weakness works · CWE-119

The program reads or writes outside the bounds of an allocated buffer, corrupting adjacent memory. With crafted input an attacker can overwrite control data and, with effort, redirect execution to their own code. Remediation ranges from bounds checking and safe library functions to compiler mitigations, usually alongside a careful audit of the surrounding code.
