Gentoo Linux Security Advisory
Title: libgsf: Buffer overflow (GLSA 200612-13)
Severity: normal
Exploitable: remote
Date: December 12, 2006
Bug(s): #156693
ID: 200612-13
Synopsis
libgsf improperly allocates memory allowing for a heap overflow and possibly the execution of arbitrary code.
Background
The GNOME Structured File Library is an I/O library that can read and write common file types and handle structured formats that provide file-system-in-a-file semantics.
Affected Packages
Package: gnome-extra/libgsf
Vulnerable: < 1.14.2
Unaffected: >= 1.14.2
Architectures: All supported architectures
Description
"infamous41md" has discovered that the "ole_init_info" function may allocate too little memory for storing the contents of an OLE document, resulting in a heap buffer overflow.
Impact
An attacker could entice a user to open a specially crafted OLE document, and possibly execute arbitrary code with the rights of the user opening the document.
Workaround
There is no known workaround at this time.
Resolution
All libgsf users should upgrade to the latest version: Code: | # emerge --sync
# emerge --ask --oneshot --verbose ">=gnome-extra/libgsf-1.14.2" |
