Adobe squashes critical bugs in Acrobat, Reader

The critical security flaws can lead to privilege escalation and code execution.
Written by Charlie Osborne, Contributing Writer

Adobe has released a security update which resolves two critical vulnerabilities uncovered in Adobe Acrobat and Reader software.

The software giant said the bugs are deemed critical, as they can lead to privilege escalation and arbitrary code execution in the context of the current user.

Adobe revealed the security flaws in a security bulletin published on Thursday.

The first vulnerability, CVE-2018-16011, is a use-after-free problem which can lead to arbitrary code execution if exploited -- which, in turn, could permit the execution of malware payloads, account hijacking, and more.

The second security flaw, CVE-2018-19725, is a security bypass issue which permits attackers to ramp up their privilege levels, potentially leading to attacks and system tampering taking place with additional freedoms beyond the usual confines of a user account.
