XML::Parser security vulnerability

XML::Parser is an open-source Perl-based XML document parsing module developed by contributors on CPAN. Versions of XML::Parser 2.47 and earlier contained security vulnerabilities; these vulnerabilities were caused by XML input buffer overflows, which could lead to heap corruption and system...

CVE-2006-10003: Off-by-one Error

XML::Parser versions through 2.47 for Perl has an off-by-one heap buffer overflow in stserialstack. In the case stackptr == stacksize - 1, the stack will NOT be expanded. Then the new value will be written at location ++stackptr, which equals stacksize and therefore falls just outside the allocat...
