Subject: [PATCH] install-script: Don't expand entities when parsing XML |
|
MIME-Version: 1.0 |
|
Content-Type: text/plain; charset=UTF-8 |
|
Content-Transfer-Encoding: 8bit |
|
|
|
The XML_PARSE_NOENT flag to libxml will cause it to expand all entities |
|
in the input XML document when parsing. Doing this is bad practice if the |
|
XML input file comes from an untrusted source, because it can cause the |
|
XML parser to load arbitrary files that are readable by the user running |
|
XML parsing. |
|
|
|
This is basically the same fix as 47233d0b9dc (from osinfo-db-tools) |
