Mandriva Linux Security Advisory 2013-104

Mandriva Linux Security Advisory 2013-104
Posted Apr 11, 2013
Authored by Mandriva | Site mandriva.com

Mandriva Linux Security Advisory 2013-104 - Mosh versions 1.2 and earlier allow an application to cause the mosh-server to consume large amounts of CPU time with a short ANSI escape sequence. In addition, a malicious mosh-server can cause the mosh-client to consume large amounts of CPU time with a short ANSI escape sequence. This arises because there was no limit on the value of the repeat parameter in some ANSI escape sequences, so even large and nonsensical values would be interpreted by Mosh's terminal emulator.

Package : mosh
Date : April 10, 2013
Affected: Business Server 1.0
_______________________________________________________________________

Problem Description:

Updated mosh package fixes security vulnerability:

Mosh versions 1.2 and earlier allow an application to cause the
mosh-server to consume large amounts of CPU time with a short ANSI
escape sequence. In addition, a malicious mosh-server can cause the
mosh-client to consume large amounts of CPU time with a short ANSI
escape sequence. This arises because there was no limit on the value
of the repeat parameter in some ANSI escape sequences, so even large
and nonsensical values would be interpreted by Mosh's terminal emulator
(CVE-2012-2385).
