The project received a report that all versions of Apache OpenOffice through 4.1.8 can open non-http(s) hyperlinks. The problem has existed since about 2006 and the issue is also in 4.1.9. If the link is specifically crafted this could lead to untrusted code execution. It is always best practice to be careful opening documents from unknown and unverified sources. The mitigation in Apache OpenOffice 4.1.10 (unreleased) assures that a security warning is displayed giving the user the option of continuing to open the hyperlink.
A vulnerability in Apache OpenOffice scripting events allows an attacker to construct documents containing hyperlinks pointing to an executable on the target users file system. These hyperlinks can be triggered unconditionally. In fixed versions no internal protocol may be called from the document event handler and other hyperlinks require a control-click.
When loading a document with Apache Open Office 4.1.5 and earlier with smaller end line termination than the operating system uses, the defect occurs. In this case OpenOffice runs into an Arithmetic Overflow at a string length calculation.
Multiple format string vulnerabilities in (1) neon 0.24.4 and earlier, and other products that use neon including (2) Cadaver, (3) Subversion, and (4) OpenOffice, allow remote malicious WebDAV servers to execute arbitrary code.
