Chris Evans (Google Security) reported that the libexslt library that
|
|
|
|
|
is part of libxslt is affected by a heap-based buffer overflow in the
|
|
|
|
|
RC4 encryption/decryption functions.

A remote attacker could entice a user to process an XML file using a
|
|
|
|
|
specially crafted XSLT stylesheet in an application linked against
|
|
|
|
|
libxslt, possibly leading to the execution of arbitrary code with the
|
|
|
|
|
privileges of the user running the application.

There is no known workaround at this time.
