    * python: CRLF injection via the path part of the url passed to urlopen() (CVE-2019-9947)

    * python: email.utils.parseaddr wrongly parses email addresses (CVE-2019-16056)

    * python: DOS via regular expression catastrophic backtracking in apop() method in pop3lib (CVE-2018-1060)

    * python: Integer overflow in Modules/_pickle.c allows for memory exhaustion if serializing gigabytes of     data (CVE-2018-20406)

    For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and     other related information, refer to the CVE page(s) listed in the References section.

    Bug Fix(es):

    * urlsplit doesn't accept a NFKD hostname with a port number (BZ#1709340)

    * rh-python36 cannot unpickle datetime.date objects (BZ#1749103)

According to the versions of the python packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - Python's elementtree C accelerator failed to initialise     Expat's hash salt during initialization. This could     make it easy to conduct denial of service attacks     against Expat by constructing an XML document that     would cause pathological hash collisions in Expat's     internal data structures, consuming large amounts CPU     and RAM. Python 3.8, 3.7, 3.6, 3.5, 3.4, 2.7 are     believed to be vulnerable.(CVE-2018-14647)

  - An exploitable denial-of-service vulnerability exists     in the X509 certificate parser of Python.org Python     2.7.11 / 3.6.6. A specially crafted X509 certificate     can cause a NULL pointer dereference, resulting in a     denial of service. An attacker can initiate or accept     TLS connections using crafted certificates to trigger     this vulnerability.(CVE-2019-5010)

  - urllib in Python 2.x through 2.7.16 supports the     local_file: scheme, which makes it easier for remote     attackers to bypass protection mechanisms that     blacklist file: URIs, as demonstrated by triggering a     urllib.urlopen('local_file:///etc/passwd')     call.(CVE-2019-9948)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The version of AOS installed on the remote host is prior to 5.11.2. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.11.2 advisory.

  - curl before version 7.61.1 is vulnerable to a buffer overrun in the NTLM authentication code. The internal     function Curl_ntlm_core_mk_nt_hash multiplies the length of the password by two (SUM) to figure out how     large temporary storage area to allocate from the heap. The length value is then subsequently used to     iterate over the password and generate output into the allocated storage buffer. On systems with a 32 bit     size_t, the math to calculate SUM triggers an integer overflow when the password length exceeds 2GB (2^31     bytes). This integer overflow usually causes a very small buffer to actually get allocated instead of the     intended very huge one, making the use of that buffer end up in a heap buffer overflow. (This bug is     almost identical to CVE-2017-8816.) (CVE-2018-14618)

  - Gnome Pango 1.42 and later is affected by: Buffer Overflow. The impact is: The heap based buffer overflow     can be used to get code execution. The component is: function name: pango_log2vis_get_embedding_levels,     assignment of nchars and the loop condition. The attack vector is: Bug can be used when application pass     invalid utf-8 strings to functions like pango_itemize. (CVE-2019-1010238)

  - Buffer overflow in the readextension function in gif2tiff.c in LibTIFF 4.0.6 allows remote attackers to     cause a denial of service (application crash) via a crafted GIF file. (CVE-2016-3186)

  - TIFFWriteScanline in tif_write.c in LibTIFF 3.8.2 has a heap-based buffer over-read, as demonstrated by     bmp2tiff. (CVE-2018-10779)

  - The TIFFWriteDirectorySec() function in tif_dirwrite.c in LibTIFF through 4.0.9 allows remote attackers to     cause a denial of service (assertion failure and application crash) via a crafted file, a different     vulnerability than CVE-2017-13726. (CVE-2018-10963)
