Summary

Heap-based buffer overflow in PolarSSL 1.x before 1.2.17 and ARM mbed TLS (formerly PolarSSL) 1.3.x before 1.3.14 and 2.x before 2.1.2 allows remote SSL servers to cause a denial of service (client crash) and possibly execute arbitrary code via a long hostname to the server name indication (SNI) extension, which is not properly handled when creating a ClientHello message. NOTE: this identifier has been SPLIT per ADT3 due to different affected version ranges. See CVE-2015-8036 for the session ticket issue that was introduced in 1.3.0.

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Overflow Buffers
    Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
  • Client-side Injection-induced Buffer Overflow
    This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
  • Filter Failure through Buffer Overflow
    In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
  • MIME Conversion
    An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

    descriptionThis update for mbedtls fixes the following security and non-security issues : - Update to 1.3.15 - Fix potential double free if ssl_set_psk() is called more than once and some allocation fails. Cannot be forced remotely. Found by Guido Vranken, Intelworks. - Fix potential heap corruption on windows when x509_crt_parse_path() is passed a path longer than 2GB. Cannot be triggered remotely. Found by Guido Vranken, Intelworks. - Fix potential buffer overflow in some asn1_write_xxx() functions. Cannot be triggered remotely unless you create X.509 certificates based on untrusted input or write keys of untrusted origin. Found by Guido Vranken, Intelworks. - The x509 max_pathlen constraint was not enforced on intermediate certificates. Found by Nicholas Wilson, fix and tests provided by Janos Follath. #280 and #319 - Self-signed certificates were not excluded from pathlen counting, resulting in some valid X.509 being incorrectly rejected.

      - Fix 'destination buffer is too small' error in
        cert_write program. Found and fixed by Jonathan Leroy,
        Inikup.
    
      - Update to 1.3.14
    
      - Added fix for CVE-2015-5291 (boo#949380) to prevent heap
        corruption due to buffer overflow of the hostname or
        session ticket. Found by Guido Vranken, Intelworks.
    
      - Fix stack-based buffer overflow in pkcs12 decryption
        (used by mbedtls_pk_parse_key(file)() when the password
        is > 129 bytes. Found by Guido Vranken, Intelworks. Not
        triggerable remotely.
    
      - Fix potential buffer overflow in
        mbedtls_mpi_read_string(). Found by Guido Vranken,
        Intelworks. Not exploitable remotely in the context of
        TLS, but might be in other uses. On 32 bit machines,
        requires reading a string of close to or larger than 1GB
        to exploit; on 64 bit machines, would require reading a
        string of close to or larger than 2^62 bytes.
    
      - Fix potential random memory allocation in
        mbedtls_pem_read_buffer() on crafted PEM input data.
        Found and fix provided by Guido Vranken, Intelworks. Not
        triggerable remotely in TLS. Triggerable remotely if you
        accept PEM data from an untrusted source.
    
      - Fix potential double-free if ssl_set_psk() is called
        repeatedly on the same ssl_context object and some
        memory allocations fail. Found by Guido Vranken,
        Intelworks. Can not be forced remotely.
    
      - Fix possible heap buffer overflow in base64_encode()
        when the input buffer is 512MB or larger on 32-bit
        platforms. Found by Guido Vranken, Intelworks. Found by
        Guido Vranken. Not trigerrable remotely in TLS.
    
      - Fix potential heap buffer overflow in servers that
        perform client authentication against a crafted CA cert.
        Cannot be triggered remotely unless you allow third
        parties to pick trust CAs for client auth. Found by
        Guido Vranken, Intelworks.
    
      - Fix compile error in net.c with musl libc. found and
        patch provided by zhasha (#278).
    
      - Fix macroization of 'inline' keywork when building as
        c++. (#279)
    
      - Added checking of hostname length in ssl_set_hostname()
        to ensure domain names are compliant with RFC 1035.
    
      - Changes for 1.3.13
    
      - Fix possible client-side NULL pointer dereference (read)
        when the client tries to continue the handshake after it
        failed (a misuse of the API). (Found and patch provided
        by Fabian Foerg, Gotham Digital Science using afl-fuzz.)
    
      - Add countermeasure against lenstra's rsa-crt attack for
        pkcs#1 v1.5 signatures. (Found by Florian Weimer, Red
        Hat.)
        https://securityblog.redhat.com/2015/09/02/factoring-rsa
        -keys-with-tls-perfect-forward-secrecy/
    
      - Setting ssl_min_dhm_bytes in config.h had no effect
        (overriden in ssl.h) (found by Fabio Solari) (#256)
    
      - Fix bug in mbedtls_rsa_public() and
        mbedtls_rsa_private() that could result trying to unlock
        an unlocked mutex on invalid input (found by Fredrik
        Axelsson) (#257)
    
      - Fix -wshadow warnings (found by hnrkp) (#240)
    
      - Fix unused function warning when using mbedtls_mdx_alt
        or MBEDTLS_SHAxxx_ALT (found by Henrik) (#239)
    
      - Fix memory corruption in pkey programs (found by
        yankuncheng) (#210)
    
      - Fix memory corruption on client with overlong psk
        identity, around SSL_MAX_CONTENT_LEN or higher - not
        triggerrable remotely (found by Aleksandrs Saveljevs)
        (#238)
    
      - Fix off-by-one error in parsing supported point format
        extension that caused some handshakes to fail.
    
      - When verifying a certificate chain, if an intermediate
        certificate is trusted, no later cert is checked.
        (suggested by hannes-landeholm) (#220).
    
      - Changes for 1.3.12
    
      - Increase the minimum size of diffie-hellman parameters
        accepted by the client to 1024 bits, to protect against
        Logjam attack.
    
      - Increase the size of default diffie-hellman parameters
        on the server to 2048 bits. This can be changed with
        ssl_set_dh_params().
    
      - Fix thread-safety issue in ssl debug module (found by
        edwin van vliet).
    
      - Some example programs were not built using make, not
        included in visual Studio projects (found by Kristian
        Bendiksen).
    
      - Fix build error with cmake and pre-4.5 versions of gcc
        (found by hugo Leisink).
    
      - Fix missing -static-ligcc when building shared libraries
        for windows with make.
    
      - Fix compile error with armcc5 --gnu.
    
      - Add ssl_min_dhm_bytes configuration parameter in
        config.h to choose the minimum size of Diffie-Hellman
        parameters accepted by the client.
    
      - The pem parser now accepts a trailing space at end of
        lines (#226)."

    descriptionA flaw was found in PolarSSl and mbed TLS : When the client creates its ClientHello message, due to insufficient bounds checking it can overflow the heap-based buffer containing the message while writing some extensions. Two extensions in particular could be used by a remote attacker to trigger the overflow: the session ticket extension and the server name indication (SNI) extension. Although most of the vulnerable code is not present in the Squeeze version, this upload contains at least a length check for incoming data.
