Description David Walser 2012-08-10 21:01:49 CEST

Fedora has issued an advisory on May 29:
http://lists.fedoraproject.org/pipermail/package-announce/2012-June/081972.html

Patched package for Mageia 1 uploaded.

Advisory:
========================

Updated qemu packages fix security vulnerabilities:

The change_process_uid function in os-posix.c in Qemu 0.14.0 and earlier
does not properly drop group privileges when the -runas option is used,
which allows local guest users to access restricted files on the host
(CVE-2011-2527).

Heap-based buffer overflow in the process_tx_desc function in the e1000
emulation (hw/e1000.c) in qemu-kvm 0.12, and possibly other versions,
allows guest OS users to cause a denial of service (QEMU crash) and possibly
execute arbitrary code via crafted legacy mode packets (CVE-2012-0029).

No poc that I could see.

I'll test Mageia 1 x86-64 shortly using the procedure from
https://bugs.mageia.org/show_bug.cgi?id=6694#c3

Comment 2 Dave Hodgins 2012-08-16 05:55:26 CEST

Testing complete on Mageia 1 x86-64.

I'll test Mageia 1 i586 shortly.

Whiteboard: has_procedure => has_procedure MGA1-64-OK

Comment 3 Dave Hodgins 2012-08-16 09:37:13 CEST

Testing on Mageia 1 i586 complete.

Could someone from the sysadmin team push the srpm
qemu-0.14.0-5.2.mga1.src.rpm
from Mageia 1 Core Updates Testing to Core Updates.
