Name of the Vulnerable Software and Affected Versions:
Poppler version 0.72.0
Description:
The issue is related to a reachable Object::dictLookup assertion in Poppler, which allows attackers to cause a denial of service due to the lack of a check for the dict data type. This can be demonstrated by the use of the FileSpec class in pdfdetach. The vulnerability is associated with insufficient input validation, potentially enabling a remote attacker to cause a denial of service.
Recommendations:
For Poppler version 0.72.0, consider updating to a newer version that addresses this issue, as the current version lacks a necessary check for the dict data type, leading to potential denial of service attacks. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
