Detailed vulnerability description
The vulnerability allows a remote attacker to cause DoS conditions on the target system.
The weakness exists due to out-of-bounds read in the igc_reloc_struct_ptr function in psi/igc.c when handling references to the scanner state structure by psi/ztoken.c. A remote attacker can send a specially crafted PostScript document, trick the victim into processing it, trigger out-of-bounds read and cause the application to crash.
Successful exploitation of the vulnerability results in denial of service.
