gosaml2 is a Pure Go implementation of SAML 2.0. SAML Service Providers using this library for SAML authentication support are likely susceptible to Denial of Service attacks. A bug in this library enables attackers to craft a `deflate`-compressed request which will consume significantly more memory during processing than the size of the original request. This may eventually lead to memory exhaustion and the process being killed. The maximum compression ratio achievable with `deflate` is 1032:1, so by limiting the size of bodies passed to gosaml2, limiting the rate and concurrency of calls, and ensuring that lots of memory is available to the process it _may_ be possible to help Go's garbage collector "keep up". Implementors are encouraged not to rely on this. This issue is fixed in version 0.9.0.

This affects all versions <0.7.0 of package github.com/russellhaering/gosaml2. There is a crash on nil-pointer dereference caused by sending malformed XML signatures.

The GOsa_Filter_Settings cookie in GONICUS GOsa 2.7.5.2 is vulnerable to PHP objection injection, which allows a remote authenticated attacker to perform file deletions (in the context of the user account that runs the web server) via a crafted cookie value, because unserialize is used to restore filter settings from a cookie.

Incorrect Access Control in the LDAP class of GONICUS GOsa through 2019-04-11 allows an attacker to log into any account with a username containing the case-insensitive substring "success" when an arbitrary password is provided.

GONICUS GOsa version before commit 56070d6289d47ba3f5918885954dcceb75606001 contains a Cross Site Scripting (XSS) vulnerability in change password form (html/password.php, #308) that can result in injection of arbitrary web script or HTML. This attack appear to be exploitable via the victim must open a specially crafted web page. This vulnerability appears to have been fixed in after commit 56070d6289d47ba3f5918885954dcceb75606001.

Cross-site scripting (XSS) vulnerability in the displayLogin function in html/index.php in GOsa allows remote attackers to inject arbitrary web script or HTML via the username.

The generate_smb_nt_hash function in include/functions.inc in GOsa allows remote attackers to execute arbitrary commands via a crafted password.

Multiple PHP remote file inclusion vulnerabilities in GoSamba 1.0.1 allow remote attackers to execute arbitrary PHP code via a URL in the include_path parameter to (1) HTML_oben.php, (2) inc_freigabe.php, (3) inc_freigabe1.php, or (4) inc_freigabe3.php in include/; (5) inc_group.php; (6) inc_manager.php; (7) inc_newgroup.php; (8) inc_smb_conf.php; (9) inc_user.php; or (10) main.php.
