syslog-ng is an enhanced log daemo. Prior to version 4.8.2, tlswildcardmatch() matches on certificates such as foo..bar although that is not allowed. It is also possible to pass partial wildcards such as foo.ac.bar which glib matches but should be avoided / invalidated. This issue could have an impact on TLS connections, such as in man-in-the-middle situations. Version 4.8.2 contains a fix for the issue.

One Identity Password Manager before 5.13.1 allows Kiosk Escape. This product enables users to reset their Active Directory passwords on the login screen of a Windows client. It launches a Chromium based browser in Kiosk mode to provide the reset functionality. The escape sequence is: go to the Google ReCAPTCHA section, click on the Privacy link, observe that there is a new browser window, navigate to any website that offers file upload, navigate to cmd.exe from the file explorer window, and launch cmd.exe as NT AUTHORITY\SYSTEM.

One Identity Password Manager before 5.13.1 allows Kiosk Escape. This product enables users to reset their Active Directory passwords on the login screen of a Windows client. It launches a Chromium based browser in Kiosk mode to provide the reset functionality. The escape sequence is: wait for a session timeout, click on the Help icon, observe that there is a browser window for the One Identity website, navigate to any website that offers file upload, navigate to cmd.exe from the file explorer window, and launch cmd.exe as NT AUTHORITY\SYSTEM.

One Identity Password Manager version 5.9.7.1 - An unauthenticated attacker with physical access to a workstation may upgrade privileges to SYSTEM through an unspecified method. CWE-250: Execution with Unnecessary Privileges.

An integer overflow in the RFC3164 parser in One Identity syslog-ng 3.0 through 3.37 allows remote attackers to cause a Denial of Service via crafted syslog input that is mishandled by the tcp or network function. syslog-ng Premium Edition 7.0.30 and syslog-ng Store Box 6.10.0 are also affected.

An issue was discovered in One Identity Password Manager 5.8. An attacker could enumerate valid answers for a user. It is possible for an attacker to detect a valid answer based on the HTTP response content, and reuse this answer later for a password reset on a chosen password. The enumeration is possible because, within the HTTP response content, WRONG ID is only returned when the answer is incorrect.

A UNIX Symbolic Link (Symlink) Following vulnerability in the packaging of syslog-ng of SUSE Linux Enterprise Debuginfo 11-SP3, SUSE Linux Enterprise Debuginfo 11-SP4, SUSE Linux Enterprise Module for Legacy Software 12, SUSE Linux Enterprise Point of Sale 11-SP3, SUSE Linux Enterprise Server 11-SP4-LTSS, SUSE Linux Enterprise Server for SAP 12-SP1; openSUSE Backports SLE-15-SP1, openSUSE Leap 15.1 allowed local attackers controlling the user news to escalate their privileges to root. This issue affects: SUSE Linux Enterprise Debuginfo 11-SP3 syslog-ng versions prior to 2.0.9-27.34.40.5.1. SUSE Linux Enterprise Debuginfo 11-SP4 syslog-ng versions prior to 2.0.9-27.34.40.5.1. SUSE Linux Enterprise Module for Legacy Software 12 syslog-ng versions prior to 3.6.4-12.8.1. SUSE Linux Enterprise Point of Sale 11-SP3 syslog-ng versions prior to 2.0.9-27.34.40.5.1. SUSE Linux Enterprise Server 11-SP4-LTSS syslog-ng versions prior to 2.0.9-27.34.40.5.1. SUSE Linux Enterprise Server for SAP 12-SP1 syslog-ng versions prior to 3.6.4-12.8.1. openSUSE Backports SLE-15-SP1 syslog-ng versions prior to 3.19.1-bp151.4.6.1. openSUSE Leap 15.1 syslog-ng versions prior to 3.19.1-lp151.3.6.1.

One Identity Cloud Access Manager before 8.1.4 Hotfix 1 allows CSRF for logout requests.

One Identity Cloud Access Manager before 8.1.4 Hotfix 1 allows OTP bypass via vectors involving a man in the middle, the One Identity Defender product, and replacing a failed SAML response with a successful SAML response.

One Identity Cloud Access Manager 8.1.3 does not use HTTP Strict Transport Security (HSTS), which may allow man-in-the-middle (MITM) attacks. This issue is fixed in version 8.1.4.

A denial of service flaw was found in the way syslog-ng processed certain log patterns, when 'global' flag was speficied and PCRE backend was used for matching. A remote attacker could use this flaw to cause excessive memory use by the syslog-ng process via specially-crafted pattern.

Upstream patch: [3] http://git.balabit.hu/?p=bazsi/syslog-ng-3.2.git;a=commit;h=09710c0b105e579d35c7b5f6c66d1ea5e3a3d3ff

Balabit syslog-ng 2.0, 3.0, 3.1, 3.2 OSE and PE, when running on FreeBSD or HP-UX, does not properly perform cast operations, which causes syslog-ng to use a default value of -1 to create log files with insecure permissions (07777), which allows local users to read and write to these log files.

syslog-ng does not call chdir when it calls chroot, which might allow attackers to escape the intended jail. NOTE: this is only a vulnerability when a separate vulnerability is present. This flaw affects syslog-ng versions prior to and including 2.0.9.

Balabit Syslog-NG 1.4.x before 1.4.15, and 1.5.x before 1.5.20, when using template filenames or output, does not properly track the size of a buffer when constant characters are encountered during macro expansion, which allows remote attackers to cause a denial of service and possibly execute arbitrary code.
