Use-after-free vulnerability in the xc_cpupool_getinfo function in Xen 4.1.x through 4.3.x, when using a multithreaded toolstack, does not properly handle a failure by the xc_cpumap_alloc function, which allows local users with access to management functions to cause a denial of service (heap corruption) and possibly gain privileges via unspecified vectors.

CVE-2014-1950 xen: use-after-free in xc_cpupool_getinfo() under memory pressure (XSA-88)
A flaw was reported [1] in Xen version 4.1 and later:
If xc_cpumap_alloc() fails then xc_cpupool_getinfo() will free and incorrectly
return the then-free pointer to the result structure.
An attacker may be able to cause a multi-threaded toolstack using this
function to race against itself leading to heap corruption and a
potential DoS.
Depending on the malloc implementation, privilege escalation cannot be
ruled out.
The flaw is present in Xen 4.1 onwards. Only multithreaded toolstacks
are vulnerable. Only systems where management functions (such as
domain creation) are exposed to untrusted users are vulnerable.
xl is not multithreaded, so is not vulnerable. However, multithreaded
toolstacks usin
