Description

Secunia Research has discovered a vulnerability in Evolution, which potentially can be exploited by malicious people to compromise a vulnerable system.

A format string error in the "write_html()" function in calendar/gui/e-cal-component-memo-preview.c when displaying a memo's categories can potentially be exploited to execute arbitrary code via a specially crafted shared memo containing format specifiers.

Successful exploitation requires that the user opens a shared memo in their mailbox, clicks on "Accept", and views the memo under the "Memo" tab.

NOTE: The categories are not displayed in the mailbox view of a shared memo.

The vulnerability is confirmed in version 2.8.2.1. Other versions may also be affected.

Solution
Update to version 2.26.2.

Ulf Harnhammar, Secunia Research.
