iOS, macOS, Safari, and Extra Susceptible

Sep 22, 2023THNZero Day / Vulnerability

Apple has launched one more spherical of safety patches to handle three actively exploited zero-day flaws impacting iOS, iPadOS, macOS, watchOS, and Safari, taking the whole tally of zero-day bugs found in its software program this 12 months to 16.

The listing of safety vulnerabilities is as follows –

• CVE-2023-41991 – A certificates validation situation within the Safety framework that would permit a malicious app to bypass signature validation.
• CVE-2023-41992 – A safety flaw in Kernel that would permit an area attacker to raise their privileges.
• CVE-2023-41993 – A WebKit flaw that would lead to arbitrary code execution when processing specifically crafted net content material.

Apple didn’t present extra specifics barring an acknowledgement that the “situation could have been actively exploited towards variations of iOS earlier than iOS 16.7.”

The updates can be found for the next units and working techniques –

• iOS 16.7 and iPadOS 16.7 – iPhone 8 and later, iPad Professional (all fashions), iPad Air third technology and later, iPad fifth technology and later, and iPad mini fifth technology and later
• iOS 17.0.1 and iPadOS 17.0.1 – iPhone XS and later, iPad Professional 12.9-inch 2nd technology and later, iPad Professional 10.5-inch, iPad Professional 11-inch 1st technology and later, iPad Air third technology and later, iPad sixth technology and later, iPad mini fifth technology and later
• macOS Monterey 12.7 and macOS Ventura 13.6
• watchOS 9.6.3 and watchOS 10.0.1 – Apple Watch Sequence 4 and later
• Safari 16.6.1 – macOS Huge Sur and macOS Monterey

Credited with discovering and reporting the shortcomings are Invoice Marczak of the Citizen Lab on the College of Toronto’s Munk College and Maddie Stone of Google’s Risk Evaluation Group (TAG), indicating that they might have been abused as a part of highly-targeted spyware and adware geared toward civil society members who’re at heightened threat of cyber threats.

The disclosure comes two weeks after Apple resolved two different actively exploited zero-days (CVE-2023-41061 and CVE-2023-41064) which were chained as a part of a zero-click iMessage exploit chain named BLASTPASS to deploy a mercenary spyware and adware often known as Pegasus.

This was adopted by each Google and Mozilla delivery fixes to comprise a safety flaw (CVE-2023-4863) that would lead to arbitrary code execution when processing a specifically crafted picture.

There may be proof to recommend that each CVE-2023-41064, a buffer overflow vulnerability in Apple’s Picture I/O picture parsing framework, and CVE-2023-4863, a heap buffer overflow within the WebP picture library (libwebp), might check with the identical bug, in line with Isosceles founder and former Google Venture Zero researcher Ben Hawkes.

Rezilion, in an evaluation revealed Thursday, revealed that the libwebp library is utilized in a number of working techniques, software program packages, Linux purposes, and container photographs, highlighting that the scope of the vulnerability is far broader than initially assumed.

“The excellent news is that the bug appears to be patched appropriately within the upstream libwebp, and that patch is making its technique to in every single place it ought to go,” Hawkes mentioned. “The unhealthy information is that libwebp is utilized in lots of locations, and it might be some time till the patch reaches saturation.”
