VAR-202010-1329

Vulnerability from variot - Updated: 2024-11-23 23:07

A path handling issue was addressed with improved validation. This issue is fixed in macOS Catalina 10.15.4. A malicious application may be able to overwrite arbitrary files. This vulnerability allows local attackers to escalate privileges on affected installations of Apple macOS. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.The specific flaw exists within the printtool daemon. The issue results from the lack of proper validation of printer icon data prior to further processing. An attacker can leverage this vulnerability to escalate privileges and execute code in the context of root. Apple macOS Catalina is a set of dedicated operating systems developed by Apple for Mac computers. Printing is one of the printing components. A security vulnerability exists in the Printing component of Apple macOS Catalina prior to 10.15.4
