Apple Rushes to Patch 3 New Zero-Day Flaws: iOS, macOS, Safari, and More Vulnerable

Apple has launched still one more round of security patches to address three actively exploited zero-day flaws impacting iOS, iPadOS, macOS, watchOS, and Safari, having the full tally of zero-working day bugs uncovered in its software package this 12 months to 16.

The listing of security vulnerabilities is as follows –

• CVE-2023-41991 – A certification validation issue in the Security framework that could allow a destructive application to bypass signature validation.
• CVE-2023-41992 – A security flaw in Kernel that could allow for a regional attacker to elevate their privileges.
• CVE-2023-41993 – A WebKit flaw that could result in arbitrary code execution when processing specially crafted web content.

Apple did not offer further specifics barring an acknowledgement that the “issue may perhaps have been actively exploited in opposition to versions of iOS in advance of iOS 16.7.”

The updates are out there for the adhering to gadgets and working programs –

• iOS 16.7 and iPadOS 16.7 – iPhone 8 and later, iPad Pro (all designs), iPad Air 3rd era and afterwards, iPad 5th generation and later on, and iPad mini 5th generation and later on
• iOS 17..1 and iPadOS 17..1 – iPhone XS and later on, iPad Pro 12.9-inch 2nd technology and afterwards, iPad Pro 10.5-inch, iPad Pro 11-inch 1st era and afterwards, iPad Air 3rd generation and later on, iPad 6th technology and later, iPad mini 5th era and later on

• Safari 16.6.1

Credited with identifying and reporting the shortcomings are Invoice Marczak of the Citizen Lab at the College of Toronto’s Munk College and Maddie Stone of Google’s Danger Assessment Team (TAG), indicating that they may possibly have been abused as element of extremely-targeted adware attacks aimed at civil modern society who are at heightened risk of cyber threats.

The disclosure will come two months following Apple resolved two other actively exploited zero-days (CVE-2023-41061 and CVE-2023-41064) that have been chained as element of a zero-click on iMessage exploit chain named BLASTPASS to deploy a mercenary adware known as Pegasus.

This was adopted by equally Google and Mozilla delivery fixes to incorporate a security flaw (CVE-2023-4863) that could outcome in arbitrary code execution when processing a specially crafted image.

There is evidence to suggest that both equally CVE-2023-41064, a buffer overflow vulnerability in Apple’s Impression I/O picture parsing framework, and CVE-2023-4863, a heap buffer overflow in the WebP graphic library (libwebp), could refer to the very same bug, according to Isosceles founder and previous Google Undertaking Zero researcher Ben Hawkes.

Rezilion, in an analysis released Thursday, revealed that the libwebp library is used in a number of running systems, software offers, Linux apps, and container visuals, highlighting that the scope of the vulnerability is significantly broader than at first assumed.

“The fantastic news is that the bug seems to be patched appropriately in the upstream libwebp, and that patch is producing its way to everywhere you go it ought to go,” Hawkes said. “The terrible information is that libwebp is utilized in a great deal of areas, and it could be a even though right until the patch reaches saturation.”
