A vulnerability in libxml2 could result in Denial of Service.
| Package | dev-libs/libxml2 on all architectures |
|---|---|
| Affected versions | < 2.9.2 |
| Unaffected versions | >= 2.9.2 |
libxml2 is the XML C parser and toolkit developed for the Gnome project.
parser.c in libxml2 before 2.9.2 does not properly prevent entity expansion even when entity substitution has been disabled.
A context-dependent attacker could entice a user to a specially crafted XML file using an application linked against libxml2, possibly resulting in a Denial of Service condition.
There is no known workaround at this time.
All libxml2 users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-libs/libxml2-2.9.2"
Packages which depend on this library may need to be recompiled. Tools such as revdep-rebuild may assist in identifying these packages.
