Description Johannes Segitz 2017-12-21 07:31:09 UTC 
CVE-2017-17805

The Salsa20 encryption algorithm in the Linux kernel before 4.14.8 does 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.

Comment 1 Takashi Iwai 2017-12-21 14:06:27 UTC 
TW is fixed with 4.14.8 stable updates.
The fix was backported to SLE15, SLE12-SP2 and SLE12-SP3 branches.
Comment 2 Takashi Iwai 2017-12-21 14:21:10 UTC 
Backported to cve/linux-3.12, cve/linux-3.0 and cve/linux-2.6.32 branches, too.
cve/linux-2.6.16 branch doesn't hit the issue.

Reassigned back to security team.
