TITLE:
MuPDF Shading Pattern Processing Buffer Overflow Vulnerabilities
SECUNIA ADVISORY ID:
SA37494
VERIFY ADVISORY:
http://secunia.com/advisories/37494/
DESCRIPTION:
Christophe Devine has reported some vulnerabilities in MuPDF, which
can be exploited by malicious people to compromise an application
using the library.
The vulnerabilities are caused due to boundary errors within the
"pdf_loadtype4shade()", "pdf_loadtype5shade()",
"pdf_loadtype6shade()", and "pdf_loadtype7shade()" functions in
mupdf/pdf_shade4.c. This can be exploited to cause stack-based buffer
overflows by e.g. tricking a user into opening a specially crafted PDF
file in an application using the library.
SOLUTION:
Fixed in the darcs repository.
PROVIDED AND/OR DISCOVERED BY:
