iOS, macOS, Safari, and Extra Susceptible

Sep 22, 2023THNZero Day / Vulnerability

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

The record of safety vulnerabilities is as follows –

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

Apple didn’t present further specifics barring an acknowledgement that the “issue may have been actively exploited against versions of iOS before iOS 16.7.”

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

• iOS 16.7 and iPadOS 16.7 – iPhone 8 and later, iPad Professional (all fashions), iPad Air third era and later, iPad fifth era and later, and iPad mini fifth era and later
• iOS 17.0.1 and iPadOS 17.0.1 – iPhone XS and later, iPad Professional 12.9-inch 2nd era and later, iPad Professional 10.5-inch, iPad Professional 11-inch 1st era and later, iPad Air third era and later, iPad sixth era and later, iPad mini fifth era 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

Credited with discovering and reporting the shortcomings are Invoice Marczak of the Citizen Lab on the College of Toronto’s Munk Faculty and Maddie Stone of Google’s Menace Evaluation Group (TAG), indicating that they might have been abused as a part of highly-targeted spy ware assaults aimed toward civil society who’re at heightened danger 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 spy ware often called Pegasus.

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

There’s proof to counsel 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 discuss with the identical bug, in line with Isosceles founder and former Google Undertaking Zero researcher Ben Hawkes.

Rezilion, in an analysis 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 good news is that the bug seems to be patched correctly in the upstream libwebp, and that patch is making its way to everywhere it should go,” Hawkes said. “The bad news is that libwebp is used in a lot of places, and it could be a while until the patch reaches saturation.”
