Several vulnerabilities were discovered in cURL, an URL transfer library.

CVE-2016-7141

When built with NSS and the libnsspem.so library is available at runtime, allows an remote attacker to hijack the authentication of a TLS connection by leveraging reuse of a previously loaded client certificate from file for a connection for which no certificate has been set, a different vulnerability than CVE-2016-5420.

CVE-2016-7167

Multiple integer overflows in the (1) curl_escape, (2) curl_easy_escape, (3) curl_unescape, and (4) curl_easy_unescape functions in libcurl allow attackers to have unspecified impact via a string of length 0xffffffff, which triggers a heap-based buffer overflow.

CVE-2016-9586

Curl is vulnerable to a buffer overflow when doing a large floating point output in libcurl's implementation of the printf() functions. If there are any applications that accept a format string from the outside without necessary input filtering, it could allow remote attacks.

CVE-2018-16839

Curl is vulnerable to a buffer overrun in the SASL authentication code that may lead to denial of service.

CVE-2018-16842

Curl is vulnerable to a heap-based buffer over-read in the tool_msgs.c:voutf() function that may result in information exposure and denial of service.

For Debian 8 'Jessie', these problems have been fixed in version 7.38.0-4+deb8u13.

We recommend that you upgrade your curl packages.

  - CVE-2017-7407: The ourWriteOut function in     tool_writeout.c in curl might have allowed physically     proximate attackers to obtain sensitive information from     process memory in opportunistic circumstances by reading     a workstation screen during use of a --write-out     argument ending in a '%' character, which lead to a     heap-based buffer over-read (bsc#1032309).

With this release new default ciphers are active (SUSE_DEFAULT, bsc#1027712).

The remote host is affected by the vulnerability described in GLSA-201701-47 (cURL: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in cURL. Please review the       CVE identifiers and bug reports referenced for details.
  Impact :

    Remote attackers could conduct a Man-in-the-Middle attack to obtain       sensitive information, cause a Denial of Service condition, or execute       arbitrary code.
  Workaround :

    There is no known workaround at this time.

The remote host is running a version of Mac OS X version 10.x prior to 10.12.6, and is affected by multiple vulnerabilities :

 - An overflow condition exists in the curl component in the 'dprintf_formatf()' function that is triggered when handling floating point conversion. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code. (CVE-2016-9586)
 - A flaw exits in the curl component in the 'randit()' function within file lib/rand.c due to improper initialization of the 32-bit random value, which is used, for example, to generate Digest and NTLM authentication nonces, resulting in weaker cryptographic operations than expected. (CVE-2016-9594)
 - A flaw exists in the curl component in the 'allocate_conn()' function in lib/url.c when using the OCSP stapling feature for checking a X.509 certificate revocation status. The issue is triggered as the request option for OCSP stapling is not properly passed to the TLS library, resulting in no error being returned even when no proof of the validity of the certificate could be provided. A man-in-the-middle attacker can exploit this to provide a revoked certificate. (CVE-2017-2629)
 - A remote code execution vulnerability exists in the CoreAudio component due to improper validation of user-supplied input when handling movie files. An unauthenticated, remote attacker can exploit this, by convincing a user to play a specially crafted movie file, to cause a denial of service condition or the execution of arbitrary code. (CVE-2017-7008)
 - A memory corruption issue exists in the IOUSBFamily component due to improper validation of user-supplied input. A local attacker can exploit this, via a specially crafted application, to cause a denial of service condition or the execution of arbitrary code. (CVE-2017-7009)
 - Multiple out-of-bounds read errors exist in the libxml2 component due to improper handling of specially crafted XML documents. An unauthenticated, remote attacker can exploit these to disclose user information. (CVE-2017-7010, CVE-2017-7013)

 - A memory corruption issue exists in the AppleGraphicsPowerManagement component due to improper validation of input. A local attacker can exploit this to cause a denial of service condition or the execution of arbitrary code with system privileges. (CVE-2017-7021)
 - Multiple memory corruption issues exist in the kernel due to improper validation of input. A local attacker can exploit these issues to cause a denial of service condition or the execution of arbitrary code with system privileges. (CVE-2017-7022, CVE-2017-7024, CVE-2017-7026)
 - Multiple memory corruption issues exist in the kernel due to improper validation of input. A local attacker can exploit these issues to cause a denial of service condition or the execution of arbitrary code with kernel privileges. (CVE-2017-7023, CVE-2017-7025, CVE-2017-7027, CVE-2017-7069)
 - Multiple unspecified flaws exist in the kernel due to a failure to properly sanitize input. A local attacker can exploit these issues, via a specially crafted application, to disclose restricted memory contents. (CVE-2017-7028, CVE-2017-7029, CVE-2017-7067)
 - A flaw exists in the Foundation component due to improper validation of input. A unauthenticated, remote attacker can exploit this, by convincing a user to open specially crafted file, to execute arbitrary code. (CVE-2017-7031)
 - A memory corruption issue exists in the 'kext tools' component due to improper validation of input. A local attacker can exploit this to execute arbitrary code with elevated privileges. (CVE-2017-7032)
 - Multiple unspecified flaws exist in the Intel Graphics Driver component due to a failure to properly sanitize input. A local attacker can exploit these issues, via a specially crafted application, to disclose restricted memory contents. (CVE-2017-7036, CVE-2017-7045)
 - A memory corruption issue exists in the libxpc component due to improper validation of input. A local attacker can exploit this issue, via a specifically crafted application, to cause a denial of service condition or the execution of arbitrary code with system privileges. (CVE-2017-7047)
 - Multiple memory corruption issues exist in the Bluetooth component due to improper validation of input. A local attacker can exploit these issues to execute arbitrary code with system privileges. (CVE-2017-7050, CVE-2017-7051)

 - A buffer overflow condition exists in the libarchive component due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this, via a specially crafted archive file, to cause a denial of service condition or the execution of arbitrary code. (CVE-2017-7068)
 - A certificate validation bypass vulnerability exists in the curl component 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. (CVE-2017-7468)
 - A memory corruption issue exists in the Broadcom BCM43xx family Wi-Fi Chips component that allows an unauthenticated, remote attacker to execute arbitrary code. (CVE-2017-9417)
