TITLE

Juniper Networks Junos OS Buffer error vulnerability

Trust: 1.4

sources: JVNDB: JVNDB-2019-006814 // CNNVD: CNNVD-201907-672

DESCRIPTION

Insufficient validation of environment variables in the telnet client supplied in Junos OS can lead to stack-based buffer overflows, which can be exploited to bypass veriexec restrictions on Junos OS. A stack-based overflow is present in the handling of environment variables when connecting via the telnet client to remote telnet servers. This issue only affects the telnet client — accessible from the CLI or shell — in Junos OS. Inbound telnet services are not affected by this issue. This issue affects: Juniper Networks Junos OS: 12.3 versions prior to 12.3R12-S13; 12.3X48 versions prior to 12.3X48-D80; 14.1X53 versions prior to 14.1X53-D130, 14.1X53-D49; 15.1 versions prior to 15.1F6-S12, 15.1R7-S4; 15.1X49 versions prior to 15.1X49-D170; 15.1X53 versions prior to 15.1X53-D237, 15.1X53-D496, 15.1X53-D591, 15.1X53-D69; 16.1 versions prior to 16.1R3-S11, 16.1R7-S4; 16.2 versions prior to 16.2R2-S9; 17.1 versions prior to 17.1R3; 17.2 versions prior to 17.2R1-S8, 17.2R2-S7, 17.2R3-S1; 17.3 versions prior to 17.3R3-S4; 17.4 versions prior to 17.4R1-S6, 17.4R2-S3, 17.4R3; 18.1 versions prior to 18.1R2-S4, 18.1R3-S3; 18.2 versions prior to 18.2R1-S5, 18.2R2-S2, 18.2R3; 18.2X75 versions prior to 18.2X75-D40; 18.3 versions prior to 18.3R1-S3, 18.3R2; 18.4 versions prior to 18.4R1-S2, 18.4R2. Juniper Networks Junos OS Contains a buffer error vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Pillow is a Python-based image processing library. There is currently no information about this vulnerability, please feel free to follow CNNVD or manufacturer announcements. Juniper Networks Junos OS is a set of network operating system of Juniper Networks (Juniper Networks) dedicated to the company's hardware equipment. The operating system provides a secure programming interface and Junos SDK. Attackers can exploit this vulnerability to bypass veriexec restrictions. The following products and versions are affected: Juniper Networks Junos OS Release 12.3, Release 12.3X48, Release 14.1X53, Release 15.1, Release 15.1X49, Release 15.1X53, Release 16.1, Release 16.2, Release 17.1, Release 17.2, Release 17.3, Release 17.4 , Version 18.1, Version 18.2, Version 18.2X75, Version 18.3, Version 18.4. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 ============================================================================= FreeBSD-SA-19:12.telnet Security Advisory The FreeBSD Project Topic: telnet(1) client multiple vulnerabilities Category: contrib Module: contrib/telnet Announced: 2019-07-24 Credits: Juniper Networks Affects: All supported versions of FreeBSD. Corrected: 2019-07-19 15:37:29 UTC (stable/12, 12.0-STABLE) 2019-07-24 12:51:52 UTC (releng/12.0, 12.0-RELEASE-p8) 2019-07-19 15:27:53 UTC (stable/11, 11.2-STABLE) 2019-07-24 12:51:52 UTC (releng/11.2, 11.2-RELEASE-p12) 2019-07-24 12:51:52 UTC (releng/11.3, 11.3-RELEASE-p1) CVE Name: CVE-2019-0053 For general information regarding FreeBSD Security Advisories, including descriptions of the fields above, security branches, and the following sections, please visit <URL:https://security.FreeBSD.org/>. I. Background The telnet(1) command is a TELNET protocol client, used primarily to establish terminal sessions across a network. II. III. Impact These buffer overflows may be triggered when connecting to a malicious server, or by an active attacker in the network path between the client and server. Specially crafted TELNET command sequences may cause the execution of arbitrary code with the privileges of the user invoking telnet(1). IV. Workaround Do not use telnet(1) to connect to untrusted machines or over an untrusted network. V. Solution Upgrade your vulnerable system to a supported FreeBSD stable or release / security branch (releng) dated after the correction date. Perform one of the following: 1) To update your vulnerable system via a binary patch: Systems running a RELEASE version of FreeBSD on the i386 or amd64 platforms can be updated via the freebsd-update(8) utility: # freebsd-update fetch # freebsd-update install 2) To update your vulnerable system via a source code patch: The following patches have been verified to apply to the applicable FreeBSD release branches. a) Download the relevant patch from the location below, and verify the detached PGP signature using your PGP utility. # fetch https://security.FreeBSD.org/patches/SA-19:12/telnet.patch # fetch https://security.FreeBSD.org/patches/SA-19:12/telnet.patch.asc # gpg --verify telnet.patch.asc b) Apply the patch. Execute the following commands as root: # cd /usr/src # patch < /path/to/patch c) Recompile the operating system using buildworld and installworld as described in <URL:https://www.FreeBSD.org/handbook/makeworld.html>. VI. Correction details The following list contains the correction revision numbers for each affected branch. Branch/path Revision - ------------------------------------------------------------------------- stable/12/ r350139 releng/12.0/ r350281 stable/11/ r350140 releng/11.2/ r350281 releng/11.3/ r350281 - ------------------------------------------------------------------------- To see which files were modified by a particular revision, run the following command, replacing NNNNNN with the revision number, on a machine with Subversion installed: # svn diff -cNNNNNN --summarize svn://svn.freebsd.org/base Or visit the following URL, replacing NNNNNN with the revision number: <URL:https://svnweb.freebsd.org/base?view=revision&revision=NNNNNN> VII.
