Description Nils Breunese 2006-08-03 20:37:47 EDT
From the release notes of GnuPG 1.4.5: "Fixed 2 more possible memory allocation 
attacks.  They are similar to the problem we fixed with 1.4.4.  This bug can 
easily be be exploted for a DoS; remote code execution is not entirely 
impossible."
Comment 1 Nils Breunese 2006-08-03 20:40:31 EDT
Probably not only FC2 is affected, but I can only choose one specific FC 
version when reporting a bug.
Comment 2 John Dalbec 2006-08-09 14:04:59 EDT
06.30.21 CVE: Not Available
Platform: Cross Platform
Title: GnuPG Parse_Comment Remote Buffer Overflow
Description: GNU Privacy Guard (GnuPG) is an encryption application.
It is affected by a remote buffer overflow issue due to insufficient
sanitization of the "parse_comment()" function in the "parse-packet.c"
source file. GnuPG version 1.4.4 is affected.

Comment 3 Matthew Miller 2007-04-10 15:12:11 EDT
Fedora Core 2 is now completely unmaintained. These bugs can't be fixed in that
version. If the issue still persists in current Fedora Core, please reopen.
Thank you, and sorry about this.
