libgsf ole_info_read_metabat() OLE file buffer overflow
| libgsf-metabat-bo (30611) |  High Risk |
Description:
The GNOME Structured File Library (libgsf) is vulnerable to a heap-based buffer overflow, caused by improper bounds checking by the ole_info_read_metabat() function. By creating a specially-crafted OLE file, a remote attacker could overflow a buffer and execute arbitrary code on the system with the permissions of the victim, if the attacker could persuade the victim to open the file with an application linked to the vulnerable library.
