HighCVSS 7.8Exploitation Probability (EPSS)
Low risk5th percentile - higher than 5% of all known CVEs
Summary
A buffer overflow was addressed with improved bounds checking. Processing a maliciously crafted file may lead to unexpected app termination or arbitrary code execution.
Risk Assessment
An attacker could exploit this vulnerability to execute arbitrary code on the device, potentially leading to full system compromise.
Recommendation
Update iOS, iPadOS, macOS Sequoia, and macOS Tahoe to the versions mentioned in the description.
Other vulnerabilities in Apple iOS
See all- CVE-2015-5882High
The processor_set_tasks API implementation in Apple iOS before version 9 allows local users to bypass an entitlement protection mechanism and gain access to the task ports of arbitrary processes by leveraging root privileges.
- CVE-2014-4451High
Apple iOS before 8.1.1 does not properly enforce the failed-passcode limit, making it easier for physically proximate attackers to bypass the lock-screen protection mechanism via a series of guesses.
- CVE-2013-5133High
Backup in Apple iOS before 7.1 does not properly restrict symlinks, allowing remote attackers to overwrite files during a restore operation via crafted backup data.
