TITLE:
Cygwin Package Handling Security Issue

SECUNIA ADVISORY ID:
SA31271

VERIFY ADVISORY:
http://secunia.com/advisories/31271/

CRITICAL:
Not critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
Cygwin 1.x
http://secunia.com/product/15184/
Cygwin 4.x
http://secunia.com/product/2924/

DESCRIPTION:
A security issue has been reported in Cygwin, which can be exploited
by malicious people to compromise a vulnerable system.

The security issue is caused due to setup.exe downloading package
lists and packages over HTTP or FTP without proper integrity checks
before installing the packages. This can be exploited to install
malicious packages on an affected system when a user installs or
updates packages.

Successful exploitation requires that a user is tricked into using a
malicious mirror or e.g. a successful DNS spoofing attack.

The security issue is reported in setup.exe versions prior to
2.573.2.3.

SOLUTION:
Update setup.exe to version 2.573.2.3.
