GLSA-200612-03 : GnuPG: Multiple vulnerabilities
critical Nessus Plugin ID 23855
Synopsis
The remote Gentoo host is missing one or more security-related patches.Description
The remote host is affected by the vulnerability described in GLSA-200612-03 (GnuPG: Multiple vulnerabilities)Hugh Warrington has reported a boundary error in GnuPG, in the 'ask_outfile_name()' function from openfile.c: the make_printable_string() function could return a string longer than expected. Additionally, Tavis Ormandy of the Gentoo Security Team reported a design error in which a function pointer can be incorrectly dereferenced.
Impact :
A remote attacker could entice a user to interactively use GnuPG on a crafted file and trigger the boundary error, which will result in a buffer overflow. They could also entice a user to process a signed or encrypted file with gpg or gpgv, possibly called through another application like a mail client, to trigger the dereference error. Both of these vulnerabilities would result in the execution of arbitrary code with the permissions of the user running GnuPG. gpg-agent, gpgsm and other tools are not affected.
Workaround :
There is no known workaround at this time.
Solution
All GnuPG users should upgrade to the latest version:# emerge --sync # emerge --ask --oneshot --verbose '=app-crypt/gnupg-1.4*'
