Description Josh Bressers 2005-05-24 20:00:42 UTC 
Integer overflow in the BFD library for gdb before 6.3 allows
attackers to execute arbitrary code via a crafted object file that
specifies a large number of section headers, leading to a heap-based
buffer overflow.

Comment 1 Josh Bressers 2005-05-24 20:02:27 UTC 
This issue should also affect RHEL2.1 and RHEL3
Comment 6 Josh Bressers 2005-06-08 17:36:05 UTC 
ping on this issue
Comment 7 Jeff Johnston 2005-06-08 22:57:18 UTC 
I have pieced together the correct fix for bfd and have modified the gdb patch
discussed on the FSF list to add a query that allows the user to continue and
defaults to no if the .gdbinit file is untrusted.  I am currently building and
testing the patch.

Comment 14 Jakub Jelinek 2005-06-14 15:00:53 UTC 
There are already separate bzs for binutils, so this one should be assigned
to GDB crowd...
Comment 16 Jeff Johnston 2005-06-30 21:52:52 UTC 
Moving to modified as rpm has been built for RHEL-4: gdb-6.3.0.0-0.31.5
Comment 18 Josh Bressers 2005-08-01 18:52:38 UTC 
Jeff,

Additionally, how do these packages fall regarding the quarterly updates?  Are
they included in the current QU packages, or shall we wait until after U2/U6 to
release these?
Comment 19 Jeff Johnston 2005-08-02 17:27:55 UTC 
This patch is considered between the last QU update and the upcoming one.  It is
a security patch that falls outside the normal QU timeframe.  It also allows
those who do not intend to update to the next gdb QU level to get the patch on
its own.
