"The remote Oracle Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the
ELSA-2009-1335 advisory.

  - 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 mime_hdr_cmp function in crypto/asn1/asn_mime.c in OpenSSL 0.9.8t and earlier allows remote attackers
    to cause a denial of service (NULL pointer dereference and application crash) via a crafted S/MIME
    message. (CVE-2006-7250)
