Name of the Vulnerable Software and Affected Versions PDF-XChange Editor (affected versions not specified)

Description The issue is related to an out-of-bounds read in the memory due to improper validation of user-supplied data when parsing JB2 files. This can allow remote attackers to disclose sensitive information on affected installations. User interaction is required, where the target must visit a malicious page or open a malicious file. The flaw exists within the parsing of JB2 files and can result in a read past the end of an allocated object, potentially allowing an attacker to execute arbitrary code in the context of the current process.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
