Red Hat Security Advisory 2023-2653-01

The vulnerability is among a rapidly growing number of zero-day bugs that major browser vendors have reported recently.

Apple on Wednesday released a slew of updates for iOS, iPadOS, macOS, watchOS, and Safari browser to address a set of flaws it said were actively exploited in the wild. This includes a pair of zero-days that have been weaponized in a mobile surveillance campaign called Operation Triangulation that has been active since 2019. The exact threat actor behind the campaign is not known.

A flaw was found in the WebKitGTK package. An improper input validation issue may lead to a use-after-free vulnerability. This flaw allows attackers with network access to pass specially crafted web content files, causing a denial of service or arbitrary code execution. This CVE exists because of a CVE-2023-28205 security regression for the WebKitGTK package in Red Hat Enterprise Linux 8.8 and Red Hat Enterprise Linux 9.2.
