Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-129: Improper Validation of Array Index, where the product uses untrusted input when calculating or using an array index, but the product does not validate or incorrectly validates the index to ensure the index references a valid position within the array. In Simonwaldherr.de/go/zplgfa, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

ZPLGFA 1.1.1 allows attackers to cause a panic (because of an integer index out of range during a ConvertToGraphicField call) via an image of zero width. NOTE: it is unclear whether there are common use cases in which this panic could have any security consequence
