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.
A denial of service flaw was found in libxml2. A remote attacker could provide a specially crafted XML or HTML file that, when processed by an application using libxml2, would cause that application to crash.
Отчет
This issue did not affect the versions of libxml2 as shipped with Red Hat Enterprise Linux 5 and 6 as they did not include support for LZMA compression support.
