Description
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists in the t2p_write_pdf function in tools/tiff2pdf.c due to heap-based buffer overflow. A remote attacker can submit a specially crafted TIFF document, trigger out-of-bounds read in TIFFCleanup, an invalid free in TIFFClose or t2p_free, memory corruption in t2p_readwrite_pdf_image, or a double free in t2p_free and execute arbitrary code on the target system.
Successful exploitation of the vulnerability may result in system compromise.
