CVE-2008-3533 yelp: Invalid URI format string vulnerability (remote arbitrary code execution)
Last modified: 2008-10-01 14:07:50 EDT
Common Vulnerabilities and Exposures assigned an identifier CVE-2008-3533 to
the following vulnerability:
Format string vulnerability in the window_error function in
yelp-window.c in yelp in Gnome after 2.19.90 and before 2.24 allows
remote attackers to execute arbitrary code via format string
specifiers in an invalid URI on the command line, as demonstrated by
use of yelp within (1) man or (2) ghelp URI handlers in Firefox,
Evolution, and unspecified other programs.
CVE-2008-3533 This issue does not affect the versions of the yelp package,
as shipped with Red Hat Enterprise Linux 3, 4 and 5.
CVE-2008-3533: This issue affects the versions of the yelp package, as
shipped with Fedora8, Fedora9 and Fedora10.
For the sake of completeness, among current Fedora versions, this issue only matters to Fedora 8. On Fedora 9, attempt to exploit this format string flaw is detected by glibc and will only result in controlled application shutdown.
So we should consider having the fix included in F8's yelp soon, for F9+ this only needs to be treated as "crasher" bug triggered by some odd inputs.
yelp-2.20.0-12.fc8 has been submitted as an update for Fedora 8.
yelp-2.20.0-12.fc8 has been pushed to the Fedora 8 stable repository. If problems still persist, please make note of it in this bug report.
