Adobe 's scheduled October update for its Acrobat and Reader PDF software addresses Vulnerability-related.PatchVulnerability 85 vulnerabilities , including dozens of critical flaws that allow arbitrary code execution . The patches also address Vulnerability-related.PatchVulnerability multiple privilege-escalation and information-disclosure flaws , shoring up Adobe 's PDF software further following a patch for a critical Acrobat and Reader flaw plugged Vulnerability-related.PatchVulnerability two weeks ago . The bugs affect Vulnerability-related.DiscoverVulnerability Acrobat DC and Reader versions 2018.011.20063 and earlier from Adobe 's continuous track , Acrobat 2017 and Acrobat Reader 2017 2017.011.30102 , and Acrobat DC and Reader DC versions 2015.006.30452 and earlier from Adobe 's classic 2015 track . The flaws affect Vulnerability-related.DiscoverVulnerability the software running on Windows and macOS systems . This update Vulnerability-related.PatchVulnerability is the largest set of fixes Adobe 's PDF software since it swatted Vulnerability-related.PatchVulnerability 105 vulnerabilities in July . However , fortunately the company says it is not currently aware Vulnerability-related.DiscoverVulnerability of any exploits in the wild for bugs fixed Vulnerability-related.PatchVulnerability in this update Vulnerability-related.PatchVulnerability . Users and admins nonetheless should install fixed versions , according to Adobe , because if an attacker developed an exploit it could lead to arbitrary code execution in the context of the current user because the software is sandboxed . Since PDFs are still widely used in the enterprise , hackers continue to develop new techniques to break the sandbox by combining PDF attacks with operating system flaws . This happened earlier this year , prompting a warning Vulnerability-related.DiscoverVulnerability from Adobe in May after it was informed Vulnerability-related.DiscoverVulnerability by researchers at ESET and Microsoft that they 'd discovered Vulnerability-related.DiscoverVulnerability a malicious PDF using a zero-day remote code execution flaw in Reader with a sandbox-busting Windows privilege escalation flaw . Adobe credits researchers from Qihoo 360 , Cisco Talos , Beihang University , Palo Alto Networks , and Check Point for reporting Vulnerability-related.DiscoverVulnerability flaws patched Vulnerability-related.PatchVulnerability in the October update . Check Point researcher Omri Herscovici was responsible for reporting Vulnerability-related.DiscoverVulnerability 35 of this month 's bugs , all of which were information disclosure flaws .

Security biz Qualys has revealed Vulnerability-related.DiscoverVulnerability three vulnerabilities in a component of systemd , a system and service manager used in most major Linux distributions . Patches for the three flaws – CVE-2018-16864 , CVE-2018-16865 , and CVE-2018-16866 – should appear in Vulnerability-related.PatchVulnerability distro repos soon as a result of coordinated disclosure . However , Linux distributions such as Debian remain vulnerable Vulnerability-related.DiscoverVulnerability at the moment , depending on the version you have installed . `` They 're aware Vulnerability-related.DiscoverVulnerability of the issues and they 're releasing Vulnerability-related.PatchVulnerability patches , '' said Jimmy Graham , director of product management at Qualys , in a phone interview with The Register . `` I do n't believe Red Hat has released Vulnerability-related.PatchVulnerability one but it should be coming shortly . '' The bugs were found Vulnerability-related.DiscoverVulnerability in systemd-journald , a part of systemd that handles the collection and storage of log data . The first two CVEs refer to memory corruption flaws while the third involves an out of bounds error that can leak data . CVE-2018-16864 can be exploited Vulnerability-related.DiscoverVulnerability by malware running on a Linux box , or a malicious logged-in user , to crash and potentially hijack the systemd-journald system service , elevating access from user to root . CVE-2018-16865 and CVE-2018-16866 can be exploited Vulnerability-related.DiscoverVulnerability together by a local attacker to crash or hijack the root-privileged journal service . While systemd is n't universally beloved in the Linux community , Graham sees nothing unusual about the presence of the three flaws in the software . `` The noteworthiness to me is that it is very commonly found in most major distributions , '' he said . Qualys contends all systemd-based Linux distros are vulnerable Vulnerability-related.DiscoverVulnerability , though the vulnerabilities can not be exploited Vulnerability-related.DiscoverVulnerability in SUSE Linux Enterprise 15 , openSUSE Leap 15.0 , and Fedora 28 and 29 because their user-land code is compiled with GCC 's -fstack-clash-protection option . The security biz calls it a simplified stack clash – where the size of the stack gets changed to overlap with other memory areas – because it only requires the last two steps in a four step process : Clashing the stack with another memory region , moving the stack-pointer to the stack start , jumping over the stack guard-page into another memory region , and smashing the stack or memory space . The third bug , CVE-2018-16866 , appeared in Vulnerability-related.DiscoverVulnerability June 2015 ( systemd v221 ) and , Qualys says , was fixed Vulnerability-related.PatchVulnerability inadvertently in August 2018 . In code where the flaw still exists Vulnerability-related.DiscoverVulnerability , it could allow an attacker to read out of bounds information , resulting in information leakage . `` The risk [ of these issues ] is a local privilege escalation to root , '' said Graham . `` It 's something that should still be a concern because usually attackers do n't just use one vulnerability to comprise a system . They often chain vulnerabilities together . ''
