Description Lubomir Kundrak 2008-03-27 23:17:24 UTC

Common Vulnerabilities and Exposures assigned an identifier CVE-2008-1530 to the following vulnerability:

GnuPG (gpg) 1.4.8 and 2.0.8 allows remote attackers to cause a denial
of service (crash) and possibly execute arbitrary code via crafted
duplicate keys that are imported from key servers, which triggers
"memory corruption around deduplication of user IDs."

Comment 1 Lubomir Kundrak 2008-03-27 23:20:31 UTC

This only affects gunpg2 in Fedora 7 and 8 and is not really exploitable.

Comment 2 Lubomir Kundrak 2008-03-27 23:24:06 UTC

This issue does not affect versions of gnupg packages as shipped with Red Hat
Enterprise Linux versions 2.1, 3, 4 and 5.
