Synopsis

Balsa is vulnerable to a buffer overflow allowing for the user-assisted execution of arbitrary code.

Background

Balsa is a highly configurable email client for GNOME.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
mail-client/balsa	< 2.3.20	>= 2.3.20	All supported architectures

Description

Evil Ninja Squirrel discovered a stack-based buffer overflow in the ir_fetch_seq() function when receiving a long response to a FETCH command (CVE-2007-5007).

Impact

A remote attacker could entice a user to connect to a malicious or compromised IMAP server, possibly leading to the execution of arbitrary code with the rights of the user running Balsa.

Workaround

There is no known workaround at this time.

Resolution

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=mail-client/balsa-2.3.20"
