The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2022:5235 advisory.

    Python is an interpreted, interactive, object-oriented programming language, which includes modules,     classes, exceptions, very high level dynamic data types and dynamic typing. Python supports interfaces to     many system calls and libraries, as well as to various windowing systems.

    Security Fix(es):

    * python: CRLF injection via HTTP request method in httplib/http.client (CVE-2020-26116)

    * python-urllib3: CRLF injection via HTTP request method (CVE-2020-26137)

    * python: Stack-based buffer overflow in PyCArg_repr in _ctypes/callproc.c (CVE-2021-3177)

    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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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

The version of AHV installed on the remote host is prior to 20220304.242. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AHV-20220304.242 advisory.

  - In Expat (aka libexpat) before 2.4.5, there is an integer overflow in storeRawNames. (CVE-2022-25315)

  - In Expat (aka libexpat) before 2.4.3, a left shift by 29 (or more) places in the storeAtts function in     xmlparse.c can lead to realloc misbehavior (e.g., allocating too few bytes, or only freeing memory).
    (CVE-2021-45960)

  - An issue was discovered in the Bidirectional Algorithm in the Unicode Specification through 14.0. It     permits the visual reordering of characters via control sequences, which can be used to craft source code     that renders different logic than the logical ordering of tokens ingested by compilers and interpreters.
    Adversaries can leverage this to encode source code for compilers accepting Unicode such that targeted     vulnerabilities are introduced invisibly to human reviewers. NOTE: the Unicode Consortium offers the     following alternative approach to presenting this concern. An issue is noted in the nature of     international text that can affect applications that implement support for The Unicode Standard and the     Unicode Bidirectional Algorithm (all versions). Due to text display behavior when text includes left-to-     right and right-to-left characters, the visual order of tokens may be different from their logical order.
    Additionally, control characters needed to fully support the requirements of bidirectional text can     further obfuscate the logical order of tokens. Unless mitigated, an adversary could craft source code such     that the ordering of tokens perceived by human reviewers does not match what will be processed by a     compiler/interpreter/etc. The Unicode Consortium has documented this class of vulnerability in its     document, Unicode Technical Report #36, Unicode Security Considerations. The Unicode Consortium also     provides guidance on mitigations for this class of issues in Unicode Technical Standard #39, Unicode     Security Mechanisms, and in Unicode Standard Annex #31, Unicode Identifier and Pattern Syntax. Also, the     BIDI specification allows applications to tailor the implementation in ways that can mitigate misleading     visual reordering in program text; see HL4 in Unicode Standard Annex #9, Unicode Bidirectional Algorithm.
    (CVE-2021-42574)

  - An arbitrary file write vulnerability was found in GNU gzip's zgrep utility. When zgrep is applied on the     attacker's chosen file name (for example, a crafted file name), this can overwrite an attacker's content     to an arbitrary attacker-selected file. This flaw occurs due to insufficient validation when processing     filenames with two or more newlines where selected content and the target file names are embedded in     crafted multi-line file names. This flaw allows a remote, low privileged attacker to force zgrep to write     arbitrary files on the system. (CVE-2022-1271)

  - AIDE before 0.17.4 allows local users to obtain root privileges via crafted file metadata (such as XFS     extended attributes or tmpfs ACLs), because of a heap-based buffer overflow. (CVE-2021-45417)

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

The version of AHV installed on the remote host is prior to 20220304.10013. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AHV-20220304.10013 advisory.

  - http.client in Python 3.x before 3.5.10, 3.6.x before 3.6.12, 3.7.x before 3.7.9, and 3.8.x before 3.8.5     allows CRLF injection if the attacker controls the HTTP request method, as demonstrated by inserting CR     and LF control characters in the first argument of HTTPConnection.request. (CVE-2020-26116)

  - urllib3 before 1.25.9 allows CRLF injection if the attacker controls the HTTP request method, as     demonstrated by inserting CR and LF control characters in the first argument of putrequest(). NOTE: this     is similar to CVE-2020-26116. (CVE-2020-26137)

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

This update for python-urllib3 fixes the following issues :

  - CVE-2020-26137: Fixed a CRLF injection via HTTP request     method (bsc#1177120).&#9;
