GOffice is a library of document-centric objects and utilities based on GTK.
GOffice includes a copy of PCRE which is vulnerable to multiple buffer overflows and memory corruptions vulnerabilities (GLSA 200711-30).
An attacker could entice a user to open specially crafted documents with GOffice, which could possibly lead to the execution of arbitrary code, a Denial of Service or the disclosure of sensitive information.
There is no known workaround at this time.
All GOffice 0.4.x users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=x11-libs/goffice-0.4.3"
All GOffice 0.6.x users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=x11-libs/goffice-0.6.1"
