Description

This security bulletin contains information about 1 security vulnerability.


1) NULL pointer dereference (CVE-ID: CVE-2018-20751)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error in crop_page in PoDoFo 0.9.6. For a crafted PDF document, pPage->GetObject()->GetDictionary().AddKey(PdfName("MediaBox"),var) can be problematic due to the function GetObject() being called for the pPage NULL pointer object. The value of pPage at this point is 0x0, which causes a NULL pointer dereference. A remote attacker can perform a denial of service (DoS) attack.
