request
CVE-2009-1387 openssl: DTLS out-of-sequence message handling NULL deref DoS
Multiple denial of service flaws were discovered in OpenSSL's DTLS
implementation. A remote attacker could use these flaws to cause a DTLS
server to use excessive amounts of memory, or crash on an invalid memory
access or NULL pointer dereference. (CVE-2009-1377, CVE-2009-1378,
CVE-2009-1379, CVE-2009-1386, CVE-2009-1387)
Note: These flaws only affect applications that use DTLS. Scientific
Linux does not ship any DTLS client or server applications.
An input validation flaw was found in the handling of the BMPString and
UniversalString ASN1 string types in OpenSSL's ASN1_STRING_print_ex()
function. An attacker could use this flaw to create a specially-crafted
X.509 certificate that could cause applications using the affected
function to crash when printing certificate contents. (CVE-2009-0590)
Note: The affected function is rarely used. No application shipped with
Scientific Linux calls this function, for example.
These updated packages also fix the following bugs:
* "openssl smime -verify -in" verifies the signature of the input file
and the "-verify" switch expects a signed or encrypted input file.
Previously, running openssl on an S/MIME file that was not encrypted or
signed caused openssl to segfault. With this update, the input file is
now checked for a signature or encryption. Consequently, openssl now
returns an error and quits when attempting to verify an unencrypted or
unsigned S/MIME file. (BZ#472440)
* when generating RSA keys, pairwise tests were called even in non-FIPS
mode. This prevented small keys from being generated. With this update,
generating keys in non-FIPS mode no longer calls the pairwise tests and
keys as small as 32-bits can be generated in this mode. Note: In FIPS
mode, pairwise tests are still called and keys generated in this mode
must still be 1024-bits or larger. (BZ#479817)
As well, these updated packages add the following enhancements:
* both the libcrypto and libssl shared libraries, which are part of the
OpenSSL FIPS module, are now checked for integrity on initialization of
FIPS mode. (BZ#475798)
* an issuing Certificate Authority (CA) allows multiple certificate
templates to inherit the CA's Common Name (CN). Because this CN is used
as a unique identifier, each template had to have its own Certificate
Revocation List (CRL). With this update, multiple CRLs with the same
subject name can now be stored in a X509_STORE structure, with their
signature field being used to distinguish between them. (BZ#457134)
* the fipscheck library is no longer needed for rebuilding the openssl
source RPM. (BZ#475798)
