GHSA-FM49-RJMC-X5WF
Vulnerability from github – Published: 2024-05-03 03:30 – Updated: 2024-05-03 03:30Kofax Power PDF printf Uninitialized Variable Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Kofax Power PDF. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the handling of util objects. The issue results from the lack of proper initialization of memory prior to accessing it. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-20566.

Mitigation MIT-57
Strategy: Attack Surface Reduction
Ensure that critical variables are initialized before first use [REF-1485].
Mitigation
Strategy: Compilation or Build Hardening
Most compilers will complain about the use of uninitialized variables if warnings are turned on.
Mitigation
When using a language that does not require explicit declaration of variables, run or compile the software in a mode that reports undeclared or unknown variables. This may indicate the presence of a typographic error in the variable's name.
Mitigation
Strategy: Language Selection
Choose a language that is not susceptible to these issues.
Mitigation
Mitigating technologies such as safe string libraries and container abstractions could be introduced.
No CAPEC attack patterns related to this CWE.
