CVE-2009-3245 openssl: missing bn_wexpand return value checks

It was discovered that OpenSSL did not always check the return value of the bn_wexpand() function. An attacker able to trigger a memory allocation failure in that function could cause an application using the OpenSSL library to crash or, possibly, execute arbitrary code.
(CVE-2009-3245)

For the update to take effect, all programs using the openssl096b library must be restarted.

Update to upstream version 0.9.8n fixing multiple security issues:
CVE-2009-3555, CVE-2009-3245, CVE-2009-4355, and CVE-2010-0433. Refer to upstream CHANGES file for the detailed list of changes since version 0.9.8k :

  -     http://cvs.openssl.org/fileview?f=openssl/CHANGES&v=1.12     38.2.193

The remote Redhat Enterprise Linux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2010:0977 advisory.

  - openssl: NETSCAPE_REUSE_CIPHER_CHANGE_BUG downgrade-to-disabled ciphersuite attack (CVE-2008-7270)

  - openssl: missing bn_wexpand return value checks (CVE-2009-3245)

  - openssl: NETSCAPE_REUSE_CIPHER_CHANGE_BUG ciphersuite downgrade attack (CVE-2010-4180)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has openssl098e packages installed that are affected by multiple vulnerabilities:

  - OpenSSL 0.9.7 before 0.9.7l and 0.9.8 before 0.9.8d     allows remote attackers to cause a denial of service     (infinite loop and memory consumption) via malformed     ASN.1 structures that trigger an improperly handled     error condition. (CVE-2006-2937)

  - OpenSSL 0.9.7 before 0.9.7l, 0.9.8 before 0.9.8d, and     earlier versions allows attackers to cause a denial of     service (CPU consumption) via parasitic public keys with     large (1) public exponent or (2) public modulus     values in X.509 certificates that require extra time to     process when using RSA signature verification.
    (CVE-2006-2940)

  - Buffer overflow in the SSL_get_shared_ciphers function     in OpenSSL 0.9.7 before 0.9.7l, 0.9.8 before 0.9.8d, and     earlier versions has unspecified impact and remote     attack vectors involving a long list of ciphers.
    (CVE-2006-3738)

  - OpenSSL before 0.9.7, 0.9.7 before 0.9.7k, and 0.9.8     before 0.9.8c, when using an RSA key with exponent 3,     removes PKCS-1 padding before generating a hash, which     allows remote attackers to forge a PKCS #1 v1.5     signature that is signed by that RSA key and prevents     OpenSSL from correctly verifying X.509 and other     certificates that use PKCS #1. (CVE-2006-4339)

  - The get_server_hello function in the SSLv2 client code     in OpenSSL 0.9.7 before 0.9.7l, 0.9.8 before 0.9.8d, and     earlier versions allows remote servers to cause a denial     of service (client crash) via unknown vectors that     trigger a null pointer dereference. (CVE-2006-4343)

  - The BN_from_montgomery function in crypto/bn/bn_mont.c     in OpenSSL 0.9.8e and earlier does not properly perform     Montgomery multiplication, which might allow local users     to conduct a side-channel attack and retrieve RSA     private keys. (CVE-2007-3108)

  - Off-by-one error in the DTLS implementation in OpenSSL     0.9.8 before 0.9.8f allows remote attackers to execute     arbitrary code via unspecified vectors. (CVE-2007-4995)

  - Off-by-one error in the SSL_get_shared_ciphers function     in OpenSSL 0.9.7 up to 0.9.7l, and 0.9.8 up to 0.9.8f,     might allow remote attackers to execute arbitrary code     via a crafted packet that triggers a one-byte buffer     underflow. NOTE: this issue was introduced as a result     of a fix for CVE-2006-3738. As of 20071012, it is     unknown whether code execution is possible.
    (CVE-2007-5135)

  - OpenSSL 0.9.8i and earlier does not properly check the     return value from the EVP_VerifyFinal function, which     allows remote attackers to bypass validation of the     certificate chain via a malformed SSL/TLS signature for     DSA and ECDSA keys. (CVE-2008-5077)

  - The ASN1_STRING_print_ex function in OpenSSL before     0.9.8k allows remote attackers to cause a denial of     service (invalid memory access and application crash)     via vectors that trigger printing of a (1) BMPString or     (2) UniversalString with an invalid encoded length.
    (CVE-2009-0590)

  - The dtls1_buffer_record function in ssl/d1_pkt.c in     OpenSSL 0.9.8k and earlier 0.9.8 versions allows remote     attackers to cause a denial of service (memory     consumption) via a large series of future epoch DTLS     records that are buffered in a queue, aka DTLS record     buffer limitation bug. (CVE-2009-1377)

  - Multiple memory leaks in the     dtls1_process_out_of_seq_message function in     ssl/d1_both.c in OpenSSL 0.9.8k and earlier 0.9.8     versions allow remote attackers to cause a denial of     service (memory consumption) via DTLS records that (1)     are duplicates or (2) have sequence numbers much greater     than current sequence numbers, aka DTLS fragment     handling memory leak. (CVE-2009-1378)

  - Use-after-free vulnerability in the     dtls1_retrieve_buffered_fragment function in     ssl/d1_both.c in OpenSSL 1.0.0 Beta 2 allows remote     attackers to cause a denial of service (openssl s_client     crash) and possibly have unspecified other impact via a     DTLS packet, as demonstrated by a packet from a server     that uses a crafted server certificate. (CVE-2009-1379)

  - ssl/s3_pkt.c in OpenSSL before 0.9.8i allows remote     attackers to cause a denial of service (NULL pointer     dereference and daemon crash) via a DTLS     ChangeCipherSpec packet that occurs before ClientHello.
    (CVE-2009-1386)

  - The dtls1_retrieve_buffered_fragment function in     ssl/d1_both.c in OpenSSL before 1.0.0 Beta 2 allows     remote attackers to cause a denial of service (NULL     pointer dereference and daemon crash) via an out-of-     sequence DTLS handshake message, related to a fragment     bug. (CVE-2009-1387)

  - The Network Security Services (NSS) library before     3.12.3, as used in Firefox; GnuTLS before 2.6.4 and     2.7.4; OpenSSL 0.9.8 through 0.9.8k; and other products     support MD2 with X.509 certificates, which might allow     remote attackers to spoof certificates by using MD2     design flaws to generate a hash collision in less than     brute-force time. NOTE: the scope of this issue is     currently limited because the amount of computation     required is still large. (CVE-2009-2409)

  - OpenSSL before 0.9.8m does not check for a NULL return     value from bn_wexpand function calls in (1)     crypto/bn/bn_div.c, (2) crypto/bn/bn_gf2m.c, (3)     crypto/ec/ec2_smpl.c, and (4) engines/e_ubsec.c, which     has unspecified impact and context-dependent attack     vectors. (CVE-2009-3245)

  - The TLS protocol, and the SSL protocol 3.0 and possibly     earlier, as used in Microsoft Internet Information     Services (IIS) 7.0, mod_ssl in the Apache HTTP Server     2.2.14 and earlier, OpenSSL before 0.9.8l, GnuTLS 2.8.5     and earlier, Mozilla Network Security Services (NSS)     3.12.4 and earlier, multiple Cisco products, and other     products, does not properly associate renegotiation     handshakes with an existing connection, which allows     man-in-the-middle attackers to insert data into HTTPS     sessions, and possibly other types of sessions protected     by TLS or SSL, by sending an unauthenticated request     that is processed retroactively by a server in a post-     renegotiation context, related to a plaintext     injection attack, aka the Project Mogul issue.
    (CVE-2009-3555)

  - Memory leak in the zlib_stateful_finish function in     crypto/comp/c_zlib.c in OpenSSL 0.9.8l and earlier and     1.0.0 Beta through Beta 4 allows remote attackers to     cause a denial of service (memory consumption) via     vectors that trigger incorrect calls to the     CRYPTO_cleanup_all_ex_data function, as demonstrated by     use of SSLv3 and PHP with the Apache HTTP Server, a     related issue to CVE-2008-1678. (CVE-2009-4355)

  - The kssl_keytab_is_available function in ssl/kssl.c in     OpenSSL before 0.9.8n, when Kerberos is enabled but     Kerberos configuration files cannot be opened, does not     check a certain return value, which allows remote     attackers to cause a denial of service (NULL pointer     dereference and daemon crash) via SSL cipher     negotiation, as demonstrated by a chroot installation of     Dovecot or stunnel without Kerberos configuration files     inside the chroot. (CVE-2010-0433)

  - The asn1_d2i_read_bio function in crypto/asn1/a_d2i_fp.c     in OpenSSL before 0.9.8v, 1.0.0 before 1.0.0i, and 1.0.1     before 1.0.1a does not properly interpret integer data,     which allows remote attackers to conduct buffer overflow     attacks, and cause a denial of service (memory     corruption) or possibly have unspecified other impact,     via crafted DER data, as demonstrated by an X.509     certificate or an RSA public key. (CVE-2012-2110)

  - The TLS protocol 1.2 and earlier, as used in Mozilla     Firefox, Google Chrome, Qt, and other products, can     encrypt compressed data without properly obfuscating the     length of the unencrypted data, which allows man-in-the-     middle attackers to obtain plaintext HTTP headers by     observing length differences during a series of guesses     in which a string in an HTTP request potentially matches     an unknown string in an HTTP header, aka a CRIME     attack. (CVE-2012-4929)

  - OpenSSL before 0.9.8y, 1.0.0 before 1.0.0k, and 1.0.1     before 1.0.1d does not properly perform signature     verification for OCSP responses, which allows remote     OCSP servers to cause a denial of service (NULL pointer     dereference and application crash) via an invalid key.
    (CVE-2013-0166)

  - The TLS protocol 1.1 and 1.2 and the DTLS protocol 1.0     and 1.2, as used in OpenSSL, OpenJDK, PolarSSL, and     other products, do not properly consider timing side-     channel attacks on a MAC check requirement during the     processing of malformed CBC padding, which allows remote     attackers to conduct distinguishing attacks and     plaintext-recovery attacks via statistical analysis of     timing data for crafted packets, aka the Lucky     Thirteen issue. (CVE-2013-0169)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
