Description Ville Skyttä 2006-11-30 21:08:47 UTC

http://nvd.nist.gov/nvd.cfm?cvename=CVE-2006-6171

"Buffer overflow in the ask_outfile_name function in openfile.c for GnuPG (gpg)
1.4 and 2.0, when running interactively, might allow attackers to execute
arbitrary code via messages that cause the make_printable_string function to
return a longer string than expected while constructing a prompt."

FE[3456] seem affected, devel looks ok.

Comment 1 Rex Dieter 2006-11-30 21:19:27 UTC

Yucky. FC-6+ should already be fine.  Older releases need patching.

Comment 2 Ville Skyttä 2006-11-30 22:13:55 UTC

Unless I'm missing something, the upstream fix is not in FE6's 2.0.1rc1, but
only in devel's 2.0.1 final.

Comment 3 Rex Dieter 2006-12-01 12:40:37 UTC

OK, though that's contrary to what the dev's said on the gpg-dev mailing list, I
was planning on upgrading FC-6 to 2.0.1 final asap anyway.
