A further issue, CVE-2014-9419, was considered, but appears to require extensive changes with a consequent high risk of regression. It is now unlikely to be fixed in squeeze-lts.
CVE-2013-6885
It was discovered that under specific circumstances, a combination of write operations to write-combined memory and locked CPU instructions may cause a core hang on AMD 16h 00h through 0Fh processors. A local user can use this flaw to mount a denial of service (system hang) via a crafted application.
For more information please refer to the AMD CPU erratum 793 in [link moved to references]
CVE-2014-7822
It was found that the splice() system call did not validate the given file offset and length. A local unprivileged user can use this flaw to cause filesystem corruption on ext4 filesystems, or possibly other effects.
CVE-2014-8133
It was found that the espfix functionality can be bypassed by installing a 16-bit RW data segment into GDT instead of LDT (which espfix checks for) and using it for stack. A local unprivileged user could potentially use this flaw to leak kernel stack addresses.
CVE-2014-8134
It was found that the espfix functionality is wrongly disabled in a 32-bit KVM guest. A local unprivileged user could potentially use this flaw to leak kernel stack addresses.
CVE-2014-8160
It was found that a netfilter (iptables or ip6tables) rule accepting packets to a specific SCTP, DCCP, GRE or UDPlite port/endpoint could result in incorrect connection tracking state. If only the generic connection tracking module (nf_conntrack) was loaded, and not the protocol-specific connection tracking module, this would allow access to any port/endpoint of the specified protocol.
CVE-2014-9420
It was found that the ISO-9660 filesystem implementation (isofs) follows arbitrarily long chains, including loops, of Continuation Entries (CEs). This allows local users to mount a denial of service via a crafted disc image.
CVE-2014-9584
It was found that the ISO-9660 filesystem implementation (isofs) does not validate a length value in the Extensions Reference (ER) System Use Field, which allows local users to obtain sensitive information from kernel memory via a crafted disc image.
CVE-2014-9585
It was discovered that address randomisation for the vDSO in 64-bit processes is extremely biassed. A local unprivileged user could potentially use this flaw to bypass the ASLR protection mechanism.
CVE-2015-1421
It was found that the SCTP implementation could free authentication state while it was still in use, resulting in heap corruption. This could allow remote users to cause a denial of service or privilege escalation.
CVE-2015-1593
It was found that address randomisation for the initial stack in 64-bit processes was limited to 20 rather than 22 bits of entropy. A local unprivileged user could potentially use this flaw to bypass the ASLR ... [Please see the references for more information on the vulnerabilities]");
