Vulnerability from variot
SumatraPDF 2.1.1/MuPDF 1.0 allows remote attackers to cause an Integer Overflow in the lex_number() function via a corrupt PDF file. SumatraPDF and MuPDF Contains an integer overflow vulnerability.Information is acquired, information is falsified, and denial of service (DoS) May be in a state. Sumatra PDF and MuPDF are prone to an integer-overflow vulnerability because they fail to properly validate user-supplied input. An attacker can exploit this issue to execute arbitrary malicious code in the context of the affected application. Failed exploit attempts will likely crash the application. The following versions are vulnerable: MuPDF 1.0 MuPDF for iOS 1.1 Sumatra 2.1.1. ----------------------------------------------------------------------

DESCRIPTION: A vulnerability has been discovered in MuPDF, which can be exploited by malicious people to potentially compromise a user's system.
The vulnerability is caused due to a signedness error in the "pdf_repair_obj_stm()" function (pdf/pdf_repair.c) when processing a stream and can be exploited to corrupt memory via a specially crafted length number.
Successful exploitation may allow execution of arbitrary code, but requires tricking a user into opening a malicious PDF document.
The vulnerability is confirmed in version 1.0. Prior versions may also be affected.
SOLUTION: Update to version 1.1.
