Gentoo Linux Security Advisory
Title: SpamAssassin: Execution of arbitrary code (GLSA 200606-09)
Severity: high
Exploitable: remote
Date: June 11, 2006
Bug(s): #135746
ID: 200606-09
Synopsis
SpamAssassin, when running with certain options, could allow local or even remote attackers to execute arbitrary commands, possibly as the root user.
Background
SpamAssassin is an extensible email filter used to identify junk email. spamd is the daemonized version of SpamAssassin.
Affected Packages
Package: mail-filter/spamassassin
Vulnerable: < 3.1.3
Unaffected: >= 3.1.3
Architectures: All supported architectures
Description
When spamd is run with both the "--vpopmail" (-v) and "--paranoid" (-P) options, it is vulnerable to an unspecified issue.
Impact
With certain configuration options, a local or even remote attacker could execute arbitrary code with the rights of the user running spamd, which is root by default, by sending a crafted message to the spamd daemon. Furthermore, the attack can be remotely performed if the "--allowed-ips" (-A) option is present and specifies non-local adresses. Note that Gentoo Linux is not vulnerable in the default configuration.
Workaround
Don't use both the "--paranoid" (-P) and the "--vpopmail" (-v) options.
Resolution
All SpamAssassin users should upgrade to the latest version: Code: | # emerge --sync
# emerge --ask --oneshot --verbose ">=mail-filter/spamassassin-3.1.3" |
