Description:
This update for kernel-source-azure fixes the following issues:
-
CVE-2019-10638: Attackers used to be able to track the Linux kernel by the IP ID values the kernel produces for connection-less protocols. When such traffic was sent to multiple destination IP addresses, it was possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). An attack could have been conducted by hosting a crafted web page that uses WebRTC or gQUIC to force UDP traffic to attacker-controlled IP addresses. [bnc#1140575]
-
CVE-2019-10639: The Linux kernel used to allow Information Exposure (partial kernel address disclosure), leading to a KASLR bypass. Specifically, it was possible to extract the KASLR kernel image offset using the IP ID values the kernel produces for connection-less protocols. When such traffic was sent to multiple destination IP addresses, it was possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). This key contains enough bits from a kernel address (of a static variable) so when the key was extracted (via enumeration), the offset of the kernel image was exposed. This attack could be carried out remotely by the attacker forcing the target device to send UDP or ICMP traffic to attacker-controlled IP addresses. Forcing a server to send UDP traffic is trivial if the server is a DNS server. ICMP traffic is trivial if the server answers ICMP Echo requests (ping). For client targets, if the target visits the attacker's web page, then WebRTC or gQUIC can be used to force UDP traffic to attacker-controlled IP addresses. [bnc#1140577]
-
CVE-2018-20836: A race condition used to exist in smp_task_timedout() and smp_task_done() in drivers/scsi/libsas/sas_expander.c, leading to a use-after-free. [bnc#1134395]
-
CVE-2019-10126: A heap based buffer overflow in the wireless driver code was fixed. This issue might have lead to memory corruption and possibly other consequences. [bnc#1136935]
-
CVE-2019-11599: The coredump implementation did not use locking or other mechanisms to prevent vma layout or vma flags changes while it ran, which allowed local users to obtain sensitive information, cause a denial of service, or possibly have unspecified other impact by triggering a race condition with mmget_not_zero or get_task_mm calls. [bnc#1131645].
-
CVE-2019-12614: There was an unchecked kstrdup of prop->name on PowerPC platforms, which allowed an attacker to cause a denial of service (NULL pointer dereference and system crash). [bnc#1137194]
-
CVE-2018-16871: A flaw was found in the NFS implementation. An attacker who was able to mount an exported NFS filesystem was able to trigger a null pointer dereference by an invalid NFS sequence. This could panic the machine and deny access to the NFS server. Any outstanding disk writes to the NFS server will were lost. [bnc#1137103]
-
CVE-2019-12819: The function __mdiobus_register() used to call put_device(), which would trigger a fixed_mdio_bus_init use-after-free error. This would cause a denial of service. [bnc#1138291]
-
CVE-2019-12818: The nfc_llcp_build_tlv function in net/nfc/llcp_commands.c may return NULL. If the caller did not check for this, it could trigger a NULL pointer dereference. This would cause denial of service. [bnc#1138293]
-
CVE-2019-12456: An issue in the MPT3COMMAND case in _ctl_ioctl_main() allowed local users to cause a denial of service or possibly have unspecified other impact by changing the value of ioc_number between two kernel reads of that value, aka a "double fetch" vulnerability. [bsc#1136922]
-
CVE-2019-12380: An issue was in the EFI subsystem existed that mishandled memory allocation failures. Note, however, that all relevant code runs only at boot-time, before any user processes are started. Therefore, there was no possibility for an unprivileged user to exploit this issue. [bnc#1136598]
