"Description": "This update upgrades kernel-image-std-def to version 4.9.43-alt1. \nSecurity Fix(es):\n\n * BDU:2017-02488: Уязвимость функции packet_set_ring (net/packet/af_packet.c) ядра операционных систем Linux, позволяющая нарушителю повысить свои привилегии, вызвать отказ в обслуживании или выполнить произвольный код\n\n * CVE-2017-1000111: Linux kernel: heap out-of-bounds in AF_PACKET sockets. This new issue is analogous to previously disclosed CVE-2016-8655. In both cases, a socket option that changes socket state may race with safety checks in packet_set_ring. Previously with PACKET_VERSION. This time with PACKET_RESERVE. The solution is similar: lock the socket for the update. This issue may be exploitable, we did not investigate further. As this issue affects PF_PACKET sockets, it requires CAP_NET_RAW in the process namespace. But note that with user namespaces enabled, any process can create a namespace in which it has CAP_NET_RAW.\n\n * CVE-2017-1000112: Linux kernel: Exploitable memory corruption due to UFO to non-UFO path switch. When building a UFO packet with MSG_MORE __ip_append_data() calls ip_ufo_append_data() to append. However in between two send() calls, the append path can be switched from UFO to non-UFO one, which leads to a memory corruption. In case UFO packet lengths exceeds MTU, copy = maxfraglen - skb-\u003elen becomes negative on the non-UFO path and the branch to allocate new skb is taken. This triggers fragmentation and computation of fraggap = skb_prev-\u003elen - maxfraglen. Fraggap can exceed MTU, causing copy = datalen - transhdrlen - fraggap to become negative. Subsequently skb_copy_and_csum_bits() writes out-of-bounds. A similar issue is present in IPv6 code. The bug was introduced in e89e9cf539a2 (\"[IPv4/IPv6]: UFO Scatter-gather approach\") on Oct 18 2005.",
