Описание
The xz_decomp function in xzlib.c in libxml2 2.9.1 does not properly detect compression errors, which allows context-dependent attackers to cause a denial of service (process hang) via crafted XML data.

Примечания
Upstream patch: https://gitlab.gnome.org/GNOME/libxml2/-/commit/f0709e3ca8f8947f2d91ed34e92e38a4c23eae63 (v2.9.3)
You can use "xmllint --version" to verify if libxml2 is compiled with "Lzma" support.
sid's 2.9.2+zdfsg1-4 claims to have "Lzma" support but it's broken in fact...
so it barfs on the problematic file (parser error : Start tag expected,
'<' not found) even though it does not have the fix yet. The next upstream
release will fix this issue and will restore XZ support.
