Description of the vulnerability

Several vulnerabilities were announced in OpenSSH.

A local attacker can write a message (or ANSI sequences) on the tty of other users, because the tty is world-writable. It is also possible to use the TIOCSTI ioctl, in order to inject shell commands. [severity:2/4; CVE-2015-6565]

On OpenSSH Portable, a local attacker can use PAM and compromise the pre-authentication process, in order to impersonate other users. [severity:2/4; BFS-SA-2015-002, CVE-2015-6563]

On OpenSSH Portable, an attacker can compromise the pre-authentication process and force the usage of a freed memory area in PAM support, in order to trigger a denial of service, and possibly to run code. [severity:2/4; BFS-SA-2015-002, CVE-2015-6564]

Description of the vulnerability

The Linux kernel supports the Copy On Write operation, which is used to copy memory only when it is modified.

However, a local attacker can manipulate the memory, so the COW operation writes in Read Only memory.

A local attacker can therefore generate a memory corruption via a Copy On Write on the Linux kernel, in order to trigger a denial of service, and possibly to run code.

Description of the vulnerability

The Blowfish and Triple-DES symetric encryption algorithms use 64 bit blocks.

However, if they are used in CBC mode, a collision occurs after 785 GB transferred, and it is then possible to decrypt blocks with an attack lasting two days.

An attacker can therefore create a TLS/VPN session with a Blowfish/Triple-DES algorithm, and perform a two days attack, in order to decrypt data.
