Validation of an XML Signature requires verification that the hash value of the related XML-document (after any optional transformations and/or normalizations) matches a specific DigestValue-value, but also that the cryptografic signature on the SignedInfo-tree (the one that contains the DigestValue) verifies and matches a trusted public key. Within the simpleSAMLphp/xml-security library (https://github.com/simplesamlphp/xml-security), the hash is being validated using SignedElementTrait::validateReference, and the signature is being verified in SignedElementTrait::verifyInternal https://github.com/simplesamlphp/xml-security/blob/master/src/XML/SignedElementTrait.php:  What stands out is that the signature is being calculated over the canonical version of the SignedInfo-tree. The validateReference method, however, uses the original non-canonicalized version of SignedInf...

Debian Linux Security Advisory 5568-1 - It was discovered that incorrect memory management in Fast DDS, a C++ implementation of the DDS (Data Distribution Service) might result in denial of service.

A vulnerability in the ownCloud file sharing app could lead to the exposure of sensitive credentials like admin passwords.

Command injection in `main/lp/openoffice_text_document.class.php` in Chamilo LMS <= v1.11.24 allows users permitted to upload Learning Paths to obtain remote code execution via improper neutralisation of special characters.

Unrestricted file upload in `/main/inc/ajax/work.ajax.php` in Chamilo LMS <= v1.11.24 allows authenticated attackers with learner role to obtain remote code execution via uploading of PHP files.

Unrestricted file upload in big file upload functionality in `/main/inc/lib/javascript/bigupload/inc/bigUpload.php` in Chamilo LMS <= v1.11.24 allows unauthenticated attackers to perform stored cross-site scripting attacks and obtain remote code execution via uploading of web shell.

Command injection in `/main/webservices/additional_webservices.php` in Chamilo LMS <= v1.11.20 allows unauthenticated attackers to obtain remote code execution via improper neutralisation of special characters. This is a bypass of CVE-2023-34960.

Path traversal in file upload functionality in `/main/webservices/additional_webservices.php` in Chamilo LMS <= v1.11.20 allows unauthenticated attackers to perform stored cross-site scripting attacks and obtain remote code execution via arbitrary file write.

Improper sanitisation in `main/inc/lib/fileUpload.lib.php` in Chamilo LMS <= v1.11.20 on Windows and Apache installations allows unauthenticated attackers to bypass file upload security protections and obtain remote code execution via uploading of `.htaccess` file. This vulnerability may be exploited by privileged attackers or chained with unauthenticated arbitrary file write vulnerabilities, such as CVE-2023-3533, to achieve remote code execution.
