libxml-parser-perl vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 25.10
- Ubuntu 24.04 LTS
- Ubuntu 22.04 LTS

Summary:

Several security issues were fixed in XML::Parser.

Software Description:
- libxml-parser-perl: Perl module for parsing XML files

Details:

It was discovered that XML::Parser incorrectly handled certain multi-byte
UTF-8 characters. If a user or automated system were tricked into
processing specially crafted XML data, a remote attacker could use this
issue to cause XML::Parser to crash, resulting in a denial of service or to
possibly execute arbitrary code. (CVE-2006-10002)

It was discovered that XML::Parser incorrectly handled very deep element
nesting. If a user or automated system were tricked into processing
specially crafted XML data, a remote attacker could use this issue to cause
XML::Parser to crash, resulting in a denial of service or to possibly
execute arbitrary code (CVE-2006-10002)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 25.10
libxml-parser-perl 2.47-1ubuntu0.25.10.1

Ubuntu 24.04 LTS
