CVE-2012-6032
Published: 23 November 2012
Multiple integer overflows in the (1) tmh_copy_from_client and (2) tmh_copy_to_client functions in the Transcendent Memory (TMEM) in Xen 4.0, 4.1, and 4.2 allow local guest OS users to cause a denial of service (memory corruption and host crash) via unspecified vectors. NOTE: this issue was originally published as part of CVE-2012-3497, which was too general; CVE-2012-3497 has been SPLIT into this ID and others.
Notes
Author | Note |
---|---|
seth-arnold | Xen team strongly recommends against TMEM use |
mdeslaur | only 4.0 and higher ONLY installations where "tmem" is specified on the hypervisor command line are vulnerable. Most Xen installations do not do so. upstream says: "TMEM has been described by its maintainers as a technology preview, and is therefore not supported by them for use in production systems. Pending a full security audit of the code, the Xen.org security team recommends that Xen users do not enable TMEM." We will not be fixing this in Ubuntu. Marking as "ignored" |
