When loading a plist file, the plistlib module reads data in size specified by the file itself, meaning a malicious file can cause OOM and DoS issues
A flaw was found in the plistlib module in the Python standard library. The amount of data to read from a Plist file is specified in the file itself. This issue allows a specially crafted Plist file to cause an application to allocate a large amount of memory, potentially resulting in allocations errors, swapping, out-of-memory conditions or even system freezes.
Отчет
This issue can only be exploited by Python applications processing malicious or untrusted Plist files, which are not typically done in Linux systems or applications. Furthermore, this flaw can cause only a denial of service with no other security impact. Due to these reasons, this vulnerability has been rated with a moderate severity.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
