The map_yp_alias function in functions/imap_general.php in SquirrelMail before 1.4.18 and NaSMail before 1.7 allows remote attackers to execute arbitrary commands via shell metacharacters in a username string that is used by the ypmatch program.

The remote Oracle Linux 5 host has a package installed that is affected by multiple vulnerabilities as referenced in the ELSA-2009-1066 advisory.

    - fix broken patch for CVE-2009-1579
    - fix broken patch for CVE-2009-1579
    - fix: CVE-2009-1581 : CSS positioning vulnerability
    - fix: CVE-2009-1579 : Server-side code injection in map_yp_alias username map

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

A server-side code injection flaw was found in the SquirrelMail 'map_yp_alias' function. If SquirrelMail was configured to retrieve a user's IMAP server address from a Network Information Service (NIS) server via the 'map_yp_alias' function, an unauthenticated, remote attacker using a specially crafted username could use this flaw to execute arbitrary code with the privileges of the web server.
(CVE-2009-1579)

Multiple cross-site scripting (XSS) flaws were found in SquirrelMail.
An attacker could construct a carefully crafted URL, which once visited by an unsuspecting user, could cause the user's web browser to execute malicious script in the context of the visited SquirrelMail web page. (CVE-2009-1578)

It was discovered that SquirrelMail did not properly sanitize Cascading Style Sheets (CSS) directives used in HTML mail. A remote attacker could send a specially crafted email that could place mail content above SquirrelMail's controls, possibly allowing phishing and cross-site scripting attacks. (CVE-2009-1581)

The remote host is affected by the vulnerability described in GLSA-201001-08 (SquirrelMail: Multiple vulnerabilities)

    Multiple vulnerabilities were found in SquirrelMail:
    Niels     Teusink reported multiple input sanitation flaws in certain encrypted     strings in e-mail headers, related to contrib/decrypt_headers.php,     PHP_SELF and the query string (aka QUERY_STRING) (CVE-2009-1578).
    Niels Teusink also reported that the map_yp_alias() function     in functions/imap_general.php does not filter shell metacharacters in a     username and that the original patch was incomplete (CVE-2009-1381,     CVE-2009-1579).
    Tomas Hoger discovered an unspecified session fixation     vulnerability (CVE-2009-1580).
    Luc Beurton reported that functions/mime.php does not protect     the application's content from Cascading Style Sheets (CSS) positioning     in HTML e-mail messages (CVE-2009-1581).
  Impact :

    The vulnerabilities allow remote attackers to execute arbitrary code     with the privileges of the user running the web server, to hijack web     sessions via a crafted cookie, to spoof the user interface and to     conduct Cross-Site Scripting and phishing attacks, via a specially     crafted message.
  Workaround :

    There is no known workaround at this time.

An updated squirrelmail package that fixes multiple security issues is now available for Red Hat Enterprise Linux 3, 4, and 5.

This update has been rated as having important security impact by the Red Hat Security Response Team.

SquirrelMail is a standards-based webmail package written in PHP.

A server-side code injection flaw was found in the SquirrelMail 'map_yp_alias' function. If SquirrelMail was configured to retrieve a user's IMAP server address from a Network Information Service (NIS) server via the 'map_yp_alias' function, an unauthenticated, remote attacker using a specially crafted username could use this flaw to execute arbitrary code with the privileges of the web server.
(CVE-2009-1579)

Multiple cross-site scripting (XSS) flaws were found in SquirrelMail.
An attacker could construct a carefully crafted URL, which once visited by an unsuspecting user, could cause the user's web browser to execute malicious script in the context of the visited SquirrelMail web page. (CVE-2009-1578)

It was discovered that SquirrelMail did not properly sanitize Cascading Style Sheets (CSS) directives used in HTML mail. A remote attacker could send a specially crafted email that could place mail content above SquirrelMail's controls, possibly allowing phishing and cross-site scripting attacks. (CVE-2009-1581)

Users of squirrelmail should upgrade to this updated package, which contains backported patches to correct these issues.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Several remote vulnerabilities have been discovered in SquirrelMail, a webmail application. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2009-1578     Cross site scripting was possible through a number of     pages which allowed an attacker to steal sensitive     session data.

  - CVE-2009-1579, CVE-2009-1381     Code injection was possible when SquirrelMail was     configured to use the map_yp_alias function to     authenticate users. This is not the default.

  - CVE-2009-1580     It was possible to hijack an active user session by     planting a specially crafted cookie into the user's     browser.

  - CVE-2009-1581     Specially crafted HTML emails could use the CSS     positioning feature to place email content over the     SquirrelMail user interface, allowing for phishing.

The installed version of SquirrelMail fails to properly sanitize input to the '$username' variable in the 'map_yp_alias' function in 'functions/imap_general.php'.  An unauthenticated, remote attacker can exploit this to execute arbitrary code subject to the privileges of the affected web-server. 

Note that there are also reported to be several cross-site scripting vulnerabilities as well as a session fixation vulnerability, though Nessus has not tested for these.

Multiple vulnerabilities have been fixed in SquirrelMail: an XSS and input sanitization bug (both CVE-2009-1578), a server-side code execution (CVE-2009-1579), a login session hijacking bug (CVE-2009-1580) and another bug that allowed phishing and XSS attacks (CVE-2009-1581).

squirrelmail is now able to work with unsigned 32bit UID values with 32-bit version of php

The remote host is running SquirrelMail, a web-based email client. The installed version of SquirrelMail is affected by multiple vulnerabilities : 

 - Multiple cross-site scripting vulnerabilities.

 - A code-injection vulnerability affects the 'map_yp_alias' function which an attacker could exploit to execute arbitrary code subject to the privileges of the web server.

 - Multiple session-fixation issues could allow an attacker to steal an unsuspecting user's session.
