Alta
| Vetor | AV:N/AC:L/Au:N/C:P/I:P/A:P |
Name of the Vulnerable Software and Affected Versions
libxml2 versions prior to 2.9.4
Apple iOS versions prior to 9.3.2
OS X versions prior to 10.11.5
tvOS versions prior to 9.2.1
watchOS versions prior to 2.2.1
Description
The issue is caused by a buffer overflow in the libxml2 library, which can be exploited by a remote attacker using a specially crafted XML document. This can lead to arbitrary code execution or a denial of service due to memory corruption. The vulnerability is also described as a use-after-free issue in the
xmlDictComputeFastKey function, allowing remote attackers to cause a denial of service.Recommendations
For libxml2 versions prior to 2.9.4, update to version 2.9.4 or later.
For Apple iOS versions prior to 9.3.2, update to version 9.3.2 or later.
For OS X versions prior to 10.11.5, update to version 10.11.5 or later.
For tvOS versions prior to 9.2.1, update to version 9.2.1 or later.
For watchOS versions prior to 2.2.1, update to version 2.2.1 or later.
As a temporary workaround, consider restricting the use of the
xmlDictComputeFastKey function until a patch is available. Avoid using specially crafted XML documents that could exploit the buffer overflow issue.Correção
