Package : libxml-parser-perl Version : 2.46-2+deb11u1 CVE ID : CVE-2006-10003 Debian Bug : 378412

It was discovered that libxml-parser-perl, a Perl module for parsing XML files, was prone to an off-by-one heap buffer overflow in `st_serial_stack()`.

This update also includes a follow-up improvement change for CVE-2006-10002 (buffer overwrite in `parse_stream()`.)

For Debian 11 bullseye, these problems have been fixed in version 2.46-2+deb11u1.
