[Secure-testing-team] Bug#484639: Two buffer overflows in evolution
Package: evolution Version: 2.22.2-1 Severity: grave Tags: security, patch Justification: user security hole Hi The following CVEs[0][1] have been issued against evolution. CVE-2008-1108: The vulnerability is caused due to a boundary error when parsing timezone strings contained within iCalendar attachments. This can be exploited to overflow a static buffer via an overly long timezone string. Successful exploitation allows execution of arbitrary code, but requires that the ITip Formatter plugin is disabled. CVE-2008-2119: The vulnerability is caused due to a boundary error when replying to an iCalendar request while in calendar view. This can be exploited to cause a heap-based buffer overflow via an overly long "DESCRIPTION" property included in an iCalendar attachment. Successful exploitation allows execution of arbitrary code, but requires that the user accepts the iCalendar request and replies to it from the "Calendars" window. The gentoo bugreport can be found here[2] together with patches[3][4]. Please mention the CVE ids in your changelog, when you fix the issues.
