Description of the vulnerability
The tiff2pdf tool of the libtiff suite is used to convert a TIFF image to a PDF document.
The t2_process_jpeg_strip() function of the tiff2pdf.c file processes the strip encoding of image data. However, if the TIFF image uses invalid values, a buffer overflow occurs.
An attacker can therefore invite the victim to open a malicious TIFF image with tiff2pdf, in order to create a denial of service or to execute code.Complete Vigil@nce bulletin....
