From ${URL} : We find a vulnerability in the way JasPer's jas_matrix_create() function parsed certain JPEG 2000 image files. jas_matrix_t *jas_matrix_create(int numrows, int numcols) { ....... if (matrix->maxrows_ > 0) { if (!(matrix->rows_ = jas_malloc(matrix->maxrows_ * sizeof(jas_seqent_t *)))) { ................ matrix->maxrows_ > 0 ,but matrix->maxrows_ *sizeof(jas_seqent_t *) can cause Integer overflow. Reported by Qihoo 360 Codesafe Team POC: https://bugzilla.redhat.com/attachment.cgi?id=1109156 @maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.
