Apple's recent security report suggests that the company has also added 39 new security patches to improve the overall performance and stability of the software, besides patching up a known jailbreak exploit used with the TaiG tool.

The exploit has been labelled as CVE-2015-1087 and its discovery has been duly credited to the TaiG jailbreak team. The description of the exploit suggests that it is a backup bug that enables an attacker to use the backup system to access restricted areas of the file system.

Here is the full changelog for the backup bug uncovered by the TaiG jailbreak team:

Backup

Available for: iPhone 4s and later, iPod touch (5th generation) and later, iPad 2 and later

CVE-ID

CVE-2015-1087: TaiG Jailbreak Team

Although the iOS 8.13 update has already rendered the TaiG jailbreak unusable, the new iOS 8.3 update has killed one more key exploit that could be used with future jailbreaks for iOS.

Nevertheless, both the TaiG and Pangu jailbreak teams have sounded positive in their recent announcements about their prospects of jailbreaking future iOS updates.
