Detailed vulnerability description

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists in coders/xbm.c in ReadXBMImage() due to lack of an EOF (End of File) check. A remote attacker can provide a specially crafted XBM file, which claims large rows and columns fields in the header but does not contain sufficient backing data, trigger the loop over the rows, consume huge CPU resources and cause the application to crash.

Successful exploitation of the vulnerability results in denial of service.
