Notes

Title of the patch
Security update for Linux Kernel Live Patch 13 for SLE 12 SP2
Description of the patch
This update for the Linux Kernel 4.4.74-92_38 fixes several issues. The following security bugs were fixed: - CVE-2017-1000112: Updated patch for this issue to be in sync with the other livepatches. Description of the issue: Prevent race condition in net-packet code that could have been exploited by unprivileged users to gain root access (bsc#1052368, bsc#1052311). - CVE-2017-12762: In drivers/isdn/i4l/isdn_net.c a user-controlled buffer was copied into a local buffer of constant size using strcpy without a length check which can cause a buffer overflow (bsc#1053150).

          "text": "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.",
