New python packages are available for Slackware 14.0, 14.1, 14.2, and
-current to fix security issues.

The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has python packages installed that are affected by multiple vulnerabilities:

  - 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)

  - An issue was discovered in urllib2 in Python 2.x through     2.7.16 and urllib in Python 3.x through 3.7.3. CRLF     injection is possible if the attacker controls a url     parameter, as demonstrated by the first argument to     urllib.request.urlopen with \r\n (specifically in the     query string after a ? character) followed by an HTTP     header or a Redis command. (CVE-2019-9740)

  - An issue was discovered in urllib2 in Python 2.x through     2.7.16 and urllib in Python 3.x through 3.7.3. CRLF     injection is possible if the attacker controls a url     parameter, as demonstrated by the first argument to     urllib.request.urlopen with \r\n (specifically in the     path component of a URL that lacks a ? character)     followed by an HTTP header or a Redis command. This is     similar to the CVE-2019-9740 query string issue.
    (CVE-2019-9947)

  - 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)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

This update for python3 to version 3.6.10 fixes the following issues :

CVE-2017-18207: Fixed a denial of service in Wave_read._read_fmt_chunk() (bsc#1083507).

The version of AOS installed on the remote host is prior to 5.10.9. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.10.9 advisory.

  - 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)

  - 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)

  - An issue was discovered in XListExtensions in ListExt.c in libX11 through 1.6.5. A malicious server can     send a reply in which the first string overflows, causing a variable to be set to NULL that will be freed     later on, leading to DoS (segmentation fault). (CVE-2018-14598)

  - An issue was discovered in libX11 through 1.6.5. The function XListExtensions in ListExt.c is vulnerable     to an off-by-one error caused by malicious server responses, leading to DoS or possibly unspecified other     impact. (CVE-2018-14599)

  - An issue was discovered in libX11 through 1.6.5. The function XListExtensions in ListExt.c interprets a     variable as signed instead of unsigned, resulting in an out-of-bounds write (of up to 128 bytes), leading     to DoS or remote code execution. (CVE-2018-14600)
