DESCRIPTION:
Some vulnerabilities have been reported in Xen, which can be
exploited by malicious, local users to disclose potentially sensitive
information, cause a DoS (Denial of Service), and gain escalated
privileges.
1) An integer overflow error within the decompression of
paravirtualised guests can be exploited to cause a buffer overflow
and potentially execute arbitrary code.
Note: This only affects management domains with 32bit userland.
2) Integer overflow errors within the decompression of
paravirtualised guests can be exploited to disclose potentially
sensitive information.
3) An error within the decompression of paravirtualised guests can be
exploited to cause an infinite loop.
SOLUTION:
Apply patches.
