Advisory ID: SLSA-2014:0594-1
Issue Date: 2014-06-03
CVE Numbers: CVE-2014-3466
CVE-2014-3467
CVE-2014-3468
CVE-2014-3469
—
A flaw was found in the way GnuTLS parsed session IDs from ServerHello
messages of the TLS/SSL handshake. A malicious server could use this flaw
to send an excessively long session ID value, which would trigger a buffer
overflow in a connecting TLS/SSL client application using GnuTLS, causing
the client application to crash or, possibly, execute arbitrary code.
(CVE-2014-3466)
It was discovered that the asn1_get_bit_der() function of the libtasn1
library incorrectly reported the length of ASN.1-encoded data. Specially
crafted ASN.1 input could cause an application using libtasn1 to perform
an out-of-bounds access operation, causing the application to crash or,
possibly, execute arbitrary code. (CVE-2014-3468)
Multiple incorrect buffer boundary check issues were discovered in
libtasn1. Specially crafted ASN.1 input could cause an application using
libtasn1 to crash. (CVE-2014-3467)
Multiple NULL pointer dereference flaws were found in libtasn1’s
asn1_read_value() function. Specially crafted ASN.1 input could cause an
application using libtasn1 to crash, if the application used the
aforementioned function in a certain way. (CVE-2014-3469)
For the update to take effect, all applications linked to the GnuTLS or
libtasn1 library must be restarted.
