An issue was discovered in OpenCV before 3.4.7 and 4.x before 4.1.1. There
is an out of bounds read in the function
cv::predictOrdered<cv::HaarEvaluator> in
modules/objdetect/src/cascadedetect.hpp, which leads to denial of service.
Notes
| Author | Note |
|---|---|
| ccdm94 | in xenial and earlier, it is necessary to backport the fix for this CVE. However, changes in the code that have occurred since the release of versions available in xenial and earlier cause this backport to be quite intrusive. To backport and properly apply the patch, it would be necessary to alter library functions that are exported, meaning that it would be necessary to alter their interfaces, which could end up causing regressions in software that uses the opencv library to operate. It also seems like a backported version of the patch does not completely fix the vulnerability, with the POC file causing a similar crash, even after the fix is applied. |
