Affected Products:
openSUSE Leap 42.3
______________________________________________________________________________

An update that solves 5 vulnerabilities and has 35 fixes is
now available.

Description:

The openSUSE Leap 42.3 kernel was updated to 4.4.104 to receive various
security and bugfixes.

This update adds mitigations for various side channel attacks against
modern CPUs that could disclose content of otherwise unreadable memory
(bnc#1068032).

– CVE-2017-5753 / “SpectreAttack”: Local attackers on systems with modern
CPUs featuring deep instruction pipelining could use attacker
controllable speculative execution over code patterns in the Linux
Kernel to leak content from otherwise not readable memory in the same
address space, allowing retrieval of passwords, cryptographic keys and
other secrets.

This problem is mitigated by adding speculative fencing on affected code
paths throughout the Linux kernel.

– CVE-2017-5715 / “SpectreAttack”: Local attackers on systems with modern
CPUs featuring branch prediction could use mispredicted branches to
speculatively execute code patterns that in turn could be made to leak
other non-readable content in the same address space, an attack similar
to CVE-2017-5753.

This problem is mitigated by disabling predictive branches, depending
on CPU architecture either by firmware updates and/or fixes in the
user-kernel privilege boundaries.

Please also check with your CPU / Hardware vendor on updated firmware
or BIOS images regarding this issue.

As this feature can have a performance impact, it can be disabled using
the “nospec” kernel commandline option.

– CVE-2017-5754 / “MeltdownAttack”: Local attackers on systems with modern
CPUs featuring deep instruction pipelining could use code patterns in
userspace to speculative executive code that would read
otherwise read protected memory, an attack similar to CVE-2017-5753.

This problem is mitigated by unmapping the Linux Kernel from the user
address space during user code execution, following a approach called
“KAISER”. The terms used here are “KAISER” / “Kernel Address Isolation”
and “PTI” / “Page Table Isolation”.

Note that this is only done on affected platforms.

This feature can be enabled / disabled by the “pti=[on|off|auto]” or
“nopti” commandline options.

The following security bugs were fixed:

– CVE-2017-17806: The HMAC implementation (crypto/hmac.c) in the Linux
kernel did not validate that the underlying cryptographic hash algorithm
is unkeyed, allowing a local attacker able to use the AF_ALG-based hash
interface (CONFIG_CRYPTO_USER_API_HASH) and the SHA-3 hash algorithm
(CONFIG_CRYPTO_SHA3) to cause a kernel stack buffer overflow by
executing a crafted sequence of system calls that encounter a missing
SHA-3 initialization (bnc#1073874).
– CVE-2017-17805: The Salsa20 encryption algorithm in the Linux kernel did
not correctly handle zero-length inputs, allowing a local attacker able
to use the AF_ALG-based skcipher interface
(CONFIG_CRYPTO_USER_API_SKCIPHER) to cause a denial of service
(uninitialized-memory free and kernel crash) or have unspecified other
impact by executing a crafted sequence of system calls that use the
blkcipher_walk API. Both the generic implementation
(crypto/salsa20_generic.c) and x86 implementation
(arch/x86/crypto/salsa20_glue.c) of Salsa20 were vulnerable
(bnc#1073792).

Affected Products:
openSUSE Leap 42.2
______________________________________________________________________________

An update that solves 5 vulnerabilities and has 19 fixes is
now available.

Description:

The openSUSE Leap 42.2 kernel was updated to 4.4.104 to receive various
security and bugfixes.

This update adds mitigations for various side channel attacks against
modern CPUs that could disclose content of otherwise unreadable memory
(bnc#1068032).

This problem is mitigated by adding speculative fencing on affected code
paths throughout the Linux kernel.

This problem is mitigated by disabling predictive branches, depending
on CPU architecture either by firmware updates and/or fixes in the
user-kernel privilege boundaries.

Please also check with your CPU / Hardware vendor on updated firmware
or BIOS images regarding this issue.

As this feature can have a performance impact, it can be disabled using
the “nospec” kernel commandline option.

Note that this is only done on affected platforms.

This feature can be enabled / disabled by the “pti=[on|off|auto]” or
“nopti” commandline options.
