A Buffer Overflow issue was discovered in Asterisk through 13.19.1, 14.x through 14.7.5, and 15.x through 15.2.1, and Certified Asterisk through 13.18-cert2. When processing a SUBSCRIBE request, the res_pjsip_pubsub module stores the accepted formats present in the Accept headers of the request. This code did not limit the number of headers it processed, despite having a fixed limit of 32. If more than 32 Accept headers were present, the code would write outside of its memory and cause a crash.
Microsoft Internet Explorer 10 and 11 allows remote attackers to obtain sensitive information from process memory via a crafted web site, aka "Internet Explorer Information Disclosure Vulnerability."
An attacker that has hijacked a Unitrends Enterprise Backup (before 9.1.2) web server session can leverage api/includes/users.php to change the password of the logged in account without knowing the current password. This allows for an account takeover.
This issue was addressed with improved checks. This issue is fixed in iOS 12.2. Processing a maliciously crafted mail message may lead to S/MIME signature spoofing.
