Xpdf DCTStream::readScanInfo() buffer overflow

xpdf-readscaninfo-bo (24025) The risk level is classified as HighHigh Risk

Description:

Xpdf is vulnerable to a heap-based buffer overflow in the DCTStream::readScanInfo() function. By creating a malicious PDF file with overly large numComps (number of components) value, a remote attacker could overflow a buffer to cause a denial of service and possibly execute arbitrary code on the system with privileges of the Xpdf process. Exploitation of this vulnerability would require the attacker to deliver the malicious PDF file to a potential victim, either by hosting the file on a Web site or sending it to the victim as an email attachment, and then the victim would have to open the file using Xpdf.

Note: This vulnerability affects multiple vendor applications that use the Xpdf code base.
