A certain algorithm in Ruby on Rails 2.1.0 through 2.2.2, and 2.3.x before 2.3.4, leaks information about the complexity of message-digest signature verification in the cookie store, which might allow remote attackers to forge a digest via multiple attempts...

pin count / page reference race in grant table code

ISSUE DESCRIPTION Grant copying code made an implication that any grant pin would be accompanied by a suitable page reference. Other portions of code, however, did not match up with that assumption. When such a grant copy operation is being done on a grant of a dying domain, the assumption turns...

Stale TLB entry due to page type release race

ISSUE DESCRIPTION x86 PV guests effect TLB flushes by way of a hypercall. Xen tries to reduce the number of TLB flushes by delaying them as much as possible. When the last type reference of a page is dropped, the need for a TLB flush before the page is re-used is recorded. If a guest TLB flush...

Unlimited recursion in linear pagetable de-typing

ISSUE DESCRIPTION x86 PV guests are permitted to set up certain forms of what is often called "linear page tables", where pagetables contain references to other pagetables at the same level or higher. Certain restrictions apply in order to fit into Xen's page type handling system. An important...
