DescriptionImager versions before 1.037 for Perl exit the process reading a raw image with an out-of-range raw_datachannels value in i_readraw_wiol. Nothing range-checks raw_datachannels. The line buffer is sized as the image width times the channel count with no overflow check, so a negative or very large count requests an excessive allocation. When it fails, Imager's allocator calls exit(3). Passing an untrusted raw_datachannels value to Imager->read() triggers an uncatchable exit.

Risk And Classification

Problem Types: CWE-190 | CWE-789 | CWE-789 CWE-789 Memory Allocation with Excessive Size Value | CWE-190 CWE-190 Integer Overflow or Wraparound
