Synopsis
Multiple vulnerabilities were found in SquirrelMail of which the worst results in remote code execution.
Background
SquirrelMail is a standards-based webmail package written in PHP.
Affected packages
Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 mail-client/squirrelmail < 1.4.19 >= 1.4.19
Description
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.
Resolution
All SquirrelMail users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=mail-client/squirrelmail-1.4.19"
