Root Cause Analysis

The analysis is primarily based on the vulnerability description and the stack trace provided in the linked GitHub issue #271, as attempts to fetch commit information were unsuccessful. The vulnerability description directly implicates ReadPCXImage in coders/pcx.c. The stack trace from the issue report confirms that ReadPCXImage calls AcquireVirtualMemory() (and AcquireMagickMemory() is also in the stack), which then fails due to an attempt to allocate a very large amount of memory. Therefore, ReadPCXImage is the function processing the malicious input and determining the size of the memory to be allocated, making it the core vulnerable function. AcquireVirtualMemory and AcquireMagickMemory are runtime indicators as they are directly involved in the crashing behavior triggered by the vulnerability in ReadPCXImage.
