Description

In Xpdf 4.01.01, there is a use-after-free vulnerability in the function JBIG2Stream::close() located at JBIG2Stream.cc. It can, for example, be triggered by sending a crafted PDF document to the pdftoppm tool.

• CWE-416Use After FreeThe product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
