(0Day) Ecava IntegraXor Inkscape PCX File Parsing Out-Of-Bound Read Information Disclosure Vulnerability
Vulnerability Details
This vulnerability allows remote attackers to disclose sensitive information on affected installations of Ecava IntegraXor. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the parsing of PCX files within the Inkscape component. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer.
