| Revision Date: | 2017-12-20 | Version: | 1 | | Title: | CVE-2017-17805 on Ubuntu 18.04 LTS (bionic) - medium. | | Description: | 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. It was discovered that the Salsa20 encryption algorithm implementations in the Linux kernel did not properly handle zero-length inputs. A local attacker could use this to cause a denial of service (system crash).
