Description
An out-of-bounds memory write flaw was found in the way GnuTLS parsed certain ECC (Elliptic Curve Cryptography) certificates or certificate signing requests (CSR). A malicious user could create a specially crafted ECC certificate or a certificate signing request that, when processed by an application compiled against GnuTLS (for example, certtool), could cause that application to crash or execute arbitrary code with the permissions of the user running the application.
Statement
This issue does not affect the version of gnutls as shipped with Red Hat Enterprise Linux 5 and 6, since it does not have support for ECC (Elliptic Curve Cryptography).
