Some vulnerabilities have been reported in libwpd, which can be exploited by malicious people to cause a DoS (Denial of Service) or to compromise an application using the library.
1) An integer overflow within the "WP6GeneralTextPacket::_readContents" function can be exploited to cause a heap-based buffer overflow by e.g. tricking a user into opening a specially crafted WordPerfect document in an application using the library.
2) Boundary errors within the "WP3TablesGroup::_readContents()" and "WP5DefinitionGroup_DefineTablesSubGroup::WP5DefinitionGroup_DefineTablesSubGroup()" functions can be exploited to cause heap-based buffer overflows by e.g. tricking a user into opening a specially crafted WordPerfect document in an application using the library.
Successful exploitation may allow the execution of arbitrary code.
The vulnerabilities are reported in versions prior to 0.8.9.
Solution: Update to version 0.8.9.
Provided and/or discovered by: Originally discovered by an anonymous researcher. Further research by Sean Larsson from iDefense revealed additional vulnerabilities.
