An intrusion prevention signature update pushed out this week by Symantec for its Endpoint Protection product has caused many devices to crash and display a so-called blue screen of death (BSOD).
After users started complaining on Symantec’s support forums and other websites, the cybersecurity firm released another update to address the issue. The version that resolves the problem is 2019/10/14 r62 and the one that caused it was 2019/10/14 r61.
Symantec has advised Endpoint Protection customers to download the new signature version or roll back to an earlier known good version.
Impacted customers said the issue appeared to affect Windows 7, 8 and 10, and some also complained about servers rebooting due to the buggy update, but they did not specify which versions of the operating system they were running.
Some reported that the issue impacted tens of machines in their organization, while others said they had over 10,000 affected systems.
