Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Signature Spoofing by Key Recreation
    An attacker obtains an authoritative or reputable signer's private signature key by exploiting a cryptographic weakness in the signature algorithm or pseudorandom number generation and then uses this key to forge signatures from the original signer to mislead a victim into performing actions that benefit the attacker.

        (CVE-2013-1987)
    
      - An overflow condition exists in X.Org libXi in the
        XListInputDevices() function, related to an unexpected
        sign extension, due to improper checking of the amount
        of memory needed to handle returned data when converting
        smaller integer types to larger ones. An
        unauthenticated, remote attacker can exploit this to
        cause a denial of service condition or the execution of
        arbitrary code. (CVE-2013-1995)
    
      - An overflow condition exists within multiple functions
        in X.Org LibXi due to improper validation of
        user-supplied input. An unauthenticated, remote attacker
        can exploit this, via a specially crafted length or
        index, to cause a denial of service condition or the
        execution of arbitrary code. (CVE-2013-1998)
    
      - An overflow condition exists in X.Org LibXt in the
        _XtResourceConfigurationEH() function due to improper
        validation of user-supplied input. An unauthenticated,
        remote attacker can exploit this, via a specially
        crafted length or index, to cause a denial of service
        condition or the execution of arbitrary code.
        (CVE-2013-2002)
    
      - An integer overflow condition exists in X.Org libXcursor
        in the  _XcursorFileHeaderCreate() function due to
        improper validation of user-supplied input. An
        unauthenticated, remote attacker can exploit this, via
        a specially crafted file, to cause a denial of service
        condition or the execution of arbitrary code.
        (CVE-2013-2003)
    
      - An uninitialized pointer flaw exists within multiple
        functions in X.Org LibXt due to a failure to check for
        proper initialization of pointers. An unauthenticated,
        remote attacker can exploit this to corrupt memory,
        resulting in a denial of service condition or the
        possible execution of arbitrary code. (CVE-2013-2005)
    
      - A flaw exists in the Application Server subcomponent
        (Apache Tomcat) due to a failure to process passwords
        when they are paired with non-existent usernames. An
        authenticated, remote attacker can exploit this, via a
        timing attack, to enumerate user account names.
        (CVE-2016-0762)
    
      - Multiple integer overflow conditions exist in s3_srvr.c,
        ssl_sess.c, and t1_lib.c due to improper use of pointer
        arithmetic for heap-buffer boundary checks. An
        unauthenticated, remote attacker can exploit these to
        cause a denial of service. (CVE-2016-2177)
    
      - An information disclosure vulnerability exists in the
        dsa_sign_setup() function in dsa_ossl.c due to a failure
        to properly ensure the use of constant-time operations.
        An unauthenticated, remote attacker can exploit this,
        via a timing side-channel attack, to disclose DSA key
        information. (CVE-2016-2178)
    
      - A denial of service vulnerability exists in the DTLS
        implementation due to a failure to properly restrict the
        lifetime of queue entries associated with unused
        out-of-order messages. An unauthenticated, remote
        attacker can exploit this, by maintaining multiple
        crafted DTLS sessions simultaneously, to exhaust memory.
        (CVE-2016-2179)
    
      - An out-of-bounds read error exists in the X.509 Public
        Key Infrastructure Time-Stamp Protocol (TSP)
        implementation. An unauthenticated, remote attacker can
        exploit this, via a crafted time-stamp file that is
        mishandled by the 'openssl ts' command, to cause a
        denial of service or to disclose sensitive information.
        (CVE-2016-2180)
    
      - A denial of service vulnerability exists in the
        Anti-Replay feature in the DTLS implementation due to
        improper handling of epoch sequence numbers in records.
        An unauthenticated, remote attacker can exploit this,
        via spoofed DTLS records, to cause legitimate packets to
        be dropped. (CVE-2016-2181)
    
      - An overflow condition exists in the BN_bn2dec() function
        in bn_print.c due to improper validation of
        user-supplied input when handling BIGNUM values. An
        unauthenticated, remote attacker can exploit this to
        crash the process. (CVE-2016-2182)
    
      - A vulnerability exists, known as SWEET32, in the 3DES
        and Blowfish algorithms due to the use of weak 64-bit
        block ciphers by default. A man-in-the-middle attacker
        who has sufficient resources can exploit this
        vulnerability, via a 'birthday' attack, to detect a
        collision that leaks the XOR between the fixed secret
        and a known plaintext, allowing the disclosure of the
        secret text, such as secure HTTPS cookies, and possibly
        resulting in the hijacking of an authenticated session.
        (CVE-2016-2183)
    
      - A flaw exists in the Core subcomponent, specifically in
        the libcurl library, due to improper validation of TLS
        certificates. An authenticated, remote attacker with the
        ability to intercept network traffic can exploit this
        issue to disclose or manipulate transmitted data by
        spoofing the TLS/SSL server using a certificate that
        appears valid. Note that this issue only affects
        versions 5.2 and 5.3. (CVE-2016-3739)
    
      - A flaw exists in cURL and libcurl when loading dynamic
        link library (DLL) files security.dll, secur32.dll, or
        ws2_32.dll due searching an insecure path which may not
        be trusted or under user control. A local attacker can
        exploit this, via a Trojan DLL file placed in the search
        path, to execute arbitrary code with the privileges of
        the user running the program. (CVE-2016-4802)
    
      - A security bypass vulnerability exists in Apache Tomcat
        due to an unspecified flaw related to web applications.
        A local attacker can exploit this, via a utility method
        that is available to web applications, to bypass a
        configured SecurityManager. (CVE-2016-5018)
    
      - An out-of-bounds access error exists in the Window
        System (X11) subcomponent, specifically in the
        XvQueryAdaptors() function in file Xv.c, when handling
        server responses. An authenticated, remote attacker can
        exploit this to impact confidentiality, integrity, and
        availability. (CVE-2016-5407)
    
      - A use-after-free error exists in cURL and libcurl within
        file lib/vtls/vtls.c due to the program attempting to
        resume TLS sessions even if the client certificate
        fails. An unauthenticated, remote attacker can exploit
        this to bypass validation mechanisms, allowing the
        attacker to possibly control which connection is used.
        (CVE-2016-5419)
    
      - A flaw exists in cURL and libcurl in the
        Curl_ssl_config_matches() function within file
        lib/vtls/vtls.c due to the program reusing TLS
        connections with different client certificates. An
        unauthenticated, remote attacker can exploit this to
        disclose sensitive cross-realm information.
        (CVE-2016-5420)
    
      - A use-after-free error exists in cURL and libcurl in
        in the close_all_connections() function within file
        lib/multi.c due to connection pointers not being
        properly cleared. An unauthenticated, remote attacker
        can exploit this to have an unspecified impact on
        confidentiality, integrity, and availability.
        (CVE-2016-5421)
    
      - A flaw exists in the tls_decrypt_ticket() function
        in t1_lib.c due to improper handling of ticket HMAC
        digests. An unauthenticated, remote attacker can exploit
        this, via a ticket that is too short, to crash the
        process, resulting in a denial of service.
        (CVE-2016-6302)
    
      - An integer overflow condition exists in the
        MDC2_Update() function in mdc2dgst.c due to improper
        validation of user-supplied input. An unauthenticated,
        remote attacker can exploit this to cause a heap-based
        buffer overflow, resulting in a denial of service
        condition or possibly the execution of arbitrary code.
        (CVE-2016-6303)
    
      - A flaw exists in the ssl_parse_clienthello_tlsext()
        function in t1_lib.c due to improper handling of overly
        large OCSP Status Request extensions from clients. An
        unauthenticated, remote attacker can exploit this, via
        large OCSP Status Request extensions, to exhaust memory
        resources, resulting in a denial of service condition.
        (CVE-2016-6304)
    
      - A flaw exists in the SSL_peek() function in
        rec_layer_s3.c due to improper handling of empty
        records. An unauthenticated, remote attacker can exploit
        this, by triggering a zero-length record in an SSL_peek
        call, to cause an infinite loop, resulting in a denial
        of service condition. (CVE-2016-6305)
    
      - An out-of-bounds read error exists in the certificate
        parser that allows an unauthenticated, remote attacker
        to cause a denial of service via crafted certificate
        operations. (CVE-2016-6306)
    
      - A denial of service vulnerability exists in the
        state-machine implementation due to a failure to check
        for an excessive length before allocating memory. An
        unauthenticated, remote attacker can exploit this, via a
        crafted TLS message, to exhaust memory resources.
        (CVE-2016-6307)
    
      - A denial of service vulnerability exists in the DTLS
        implementation due to improper handling of excessively
        long DTLS messages. An unauthenticated, remote attacker
        can exploit this, via a crafted DTLS message, to exhaust
        available memory resources. (CVE-2016-6308)
    
      - A flaw exists in Apache Tomcat within SecurityManager
        due to improper restriction of access to system
        properties by the configuration files system property
        replacement feature. A local attacker can exploit this,
        via a crafted web application, to bypass SecurityManager
        restrictions and disclose system properties.
        (CVE-2016-6794)
    
      - A flaw exists in Apache Tomcat that allows a local
        attacker to bypass a configured SecurityManager by
        changing the configuration parameters for the JSP
        Servlet. (CVE-2016-6796)
    
      - A flaw exists in Apache Tomcat due to a failure to limit
        web application access to global JNDI resources. A local
        attacker can exploit this to gain unauthorized access to
        resources. (CVE-2016-6797)
    
      - A flaw exists in Apache Tomcat when handling request
        lines containing certain invalid characters. An
        unauthenticated, remote attacker can exploit this to
        conduct HTTP response splitting attacks by injecting
        additional headers into responses. (CVE-2016-6816)
    
      - An infinite loop condition exists in Apache Tomcat in
        the HTTP/2 parser when handling overly large headers. An
        unauthenticated, remote attacker can exploit this, via a
        specially crafted request, to cause a denial of service
        condition. (CVE-2016-6817)
    
      - A carry propagation error exists in the
        Broadwell-specific Montgomery multiplication procedure
        when handling input lengths divisible by but longer than
        256 bits. This can result in transient authentication
        and key negotiation failures or reproducible erroneous
        outcomes of public-key operations with specially crafted
        input. A man-in-the-middle attacker can possibly exploit
        this issue to compromise ECDH key negotiations that
        utilize Brainpool P-512 curves. (CVE-2016-7055)
    
      - A flaw exists in cURL in the Curl_cookie_init() function
        within file lib/cookie.c when handling cookies. An
        unauthenticated, remote attacker can exploit this to
        inject new cookies for arbitrary domains.
        (CVE-2016-8615)
    
      - A flaw exists in cURL in the ConnectionExists() function
        within file lib/url.c when checking credentials supplied
        for reused connections due to the comparison being
        case-insensitive. An unauthenticated, remote attacker
        can exploit this to authenticate without knowing the
        proper case of the username and password.
        (CVE-2016-8616)
    
      - An integer overflow condition exists in cURL in the
        base64_encode() function within file lib/base64.c due to
        improper validation of certain input. An
        unauthenticated, remote attacker can exploit this to
        cause a denial of service condition or the execution of
        arbitrary code. (CVE-2016-8617)
    
      - A denial of service vulnerability exists in cURL in the
        alloc_addbyter() function within file lib/mprintf.c due
        to improper validation of overly long input when it is
        supplied to the curl_maprintf() API method. An
        unauthenticated, remote attacker can exploit this to
        free already freed memory and thereby crash the program.
        (CVE-2016-8618)
    
      - A double-free error exists in cURL in the read_data()
        function within file lib/security.c when handling
        Kerberos authentication. An unauthenticated, remote
        attacker can exploit this to free already freed memory,
        resulting in an unspecified impact on confidentiality,
        integrity, and availability. (CVE-2016-8619)
    
      - An out-of-bounds access error exists in cURL in file
        tool_urlglob.c within the globbing feature. An
        unauthenticated, remote attacker can exploit this to
        disclose memory contents or execute arbitrary code.
        (CVE-2016-8620)
    
      - An out-of-bounds error exists in cURL in the parsedate()
        function within file lib/parsedate.c when handling
        dates. An unauthenticated, remote attacker can exploit
        this to disclose memory contents or cause a denial of
        service condition. (CVE-2016-8621)
    
      - An integer truncation error exists in cURL in the
        curl_easy_unescape() function within file lib/escape.c
        when handling overly large URLs. An unauthenticated,
        remote attacker can exploit this to cause a denial of
        service condition or the execution of arbitrary code.
        (CVE-2016-8622)
    
      - A use-after-free error exists in cURL within file
        lib/cookie.c when handling shared cookies. An
        unauthenticated, remote attacker can exploit this to
        disclose memory contents. (CVE-2016-8623)
    
      - A flaw exists in cURL in the parseurlandfillconn()
        function within file lib/url.c when parsing the
        authority component of a URL with the host name part
        ending in a '#' character. An unauthenticated, remote
        attacker can exploit this to establish a connection to
        a different host than intended. (CVE-2016-8624)
    
      - A flaw exists in cURL within International Domain Names
        (IDNA) handling when translating domain names to puny
        code for DNS resolving due to using the outdated IDNA
        2003 standard instead of the IDNA 2008 standard, which
        can result in incorrect translation of a domain name.
        An unauthenticated, remote attacker can exploit this to
        cause network traffic to be redirected to a different
        host than intended. (CVE-2016-8625)
    
      - A flaw exists in Apache Tomcat within the
        catalina/mbeans/JmxRemoteLifecycleListener.java class
        that is triggered during the deserialization of Java
        objects. An unauthenticated, remote attacker can exploit
        this to execute arbitrary code. (CVE-2016-8735)
    
      - A flaw exists in the Web Server component (Apache HTTP
        Server) when handling whitespace patterns in User-Agent
        headers. An authenticated, remote attacker can exploit
        this, via a specially crafted User-Agent header, to
        cause incorrect processing of sequences of requests,
        resulting in incorrectly interpreting responses,
        polluting the cache, or disclosing content from one
        request to a second downstream user-agent.
        (CVE-2016-8743)
    
      - A NULL pointer dereference flaw exists within file
        ssl/statem/statem_clnt.c when handling parameters for
        the DHE or ECDHE key exchanges. An unauthenticated,
        remote attacker can exploit this, via specially crafted
        parameters, to cause a denial of service condition.
        (CVE-2017-3730)
    
      - A out-of-bounds read error exists exists in the Core
        subcomponent, specifically in OpenSSL, when handling
        packets using the CHACHA20/POLY1305 or RC4-MD5 ciphers.
        An unauthenticated, remote attacker can exploit this,
        via specially crafted truncated packets, to cause a
        denial of service condition. (CVE-2017-3731)
    
      - A carry propagating error exists in the x86_64
        Montgomery squaring implementation that may cause the
        BN_mod_exp() function to produce incorrect results. An
        unauthenticated, remote attacker with sufficient
        resources can exploit this to obtain sensitive
        information regarding private keys. Note that this issue
        is very similar to CVE-2015-3193. Moreover, the attacker
        would additionally need online access to an unpatched
        system using the target private key in a scenario with
        persistent DH parameters and a private key that is
        shared between multiple clients. For example, this can
        occur by default in OpenSSL DHE based SSL/TLS cipher
        suites. (CVE-2017-3732)

    descriptionAn update for curl is now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. The curl packages provide the libcurl library and the curl utility for downloading files from servers using various protocols, including HTTP, FTP, and LDAP. Security Fix(es) : * It was found that the libcurl library did not prevent TLS session resumption when the client certificate had changed. An attacker could potentially use this flaw to hijack the authentication of the connection by leveraging a previously created connection with a different client certificate. (CVE-2016-5419) * It was found that the libcurl library did not check the client certificate when choosing the TLS connection to reuse. An attacker could potentially use this flaw to hijack the authentication of the connection by leveraging a previously created connection with a different client certificate. (CVE-2016-5420) * It was found that the libcurl library using the NSS (Network Security Services) library as TLS/SSL backend incorrectly re-used client certificates for subsequent TLS connections in certain cases. An attacker could potentially use this flaw to hijack the authentication of the connection by leveraging a previously created connection with a different client certificate. (CVE-2016-7141) Additional Changes : For detailed information on changes in this release, see the Red Hat Enterprise Linux 7.3 Release Notes linked from the References section.
