Name of the Vulnerable Software and Affected Versions
No specific software or versions mentioned.
Description
The issue is related to heap overflows caused by an integer overflow when parsing images. This occurs because the chosen limit of 0x10000 for dimensions is too large for 32-bit systems, given that each pixel takes 4 bytes. By choosing the right values, it's possible to trigger an overflow, which leads to less allocated memory than needed for subsequent reads.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
