Moodle’s mobile and web service authentication endpoints did not sufficiently restrict repeated password attempts, making them susceptible to brute-force attacks.

An issue in Moodle’s timed assignment feature allowed students to bypass the time restriction, potentially giving them more time than allowed to complete an assessment.

The router’s inconsistent response to invalid course IDs allowed attackers to infer which course IDs exist, potentially aiding reconnaissance.

A serious authentication flaw allowed attackers with valid credentials to bypass multi-factor authentication under certain conditions, potentially compromising user accounts.

Moodle exposed the names of hidden groups to users who had permission to create calendar events but not to view hidden groups. This could reveal private or restricted group information.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in E2Pdf e2pdf e2pdf.This issue affects e2pdf: from n/a through <= 1.28.09.

YAML::Syck versions before 1.36 for Perl has missing null-terminators which causes out-of-bounds read and potential information disclosure Missing null terminators in token.c leads to but-of-bounds read which allows adjacent variable to be read The issue is seen with complex YAML files with a hash of all keys and empty values.  There is no indication that the issue leads to accessing memory outside that allocated to the module.

A data corruption vulnerability has been identified in the luksmeta utility when used with the LUKS1 disk encryption format. An attacker with the necessary permissions can exploit this flaw by writing a large amount of metadata to an encrypted device. The utility fails to correctly validate the available space, causing the metadata to overwrite and corrupt the user's encrypted data. This action leads to a permanent loss of the stored information. Devices using the LUKS formats other than LUKS1 are not affected by this issue.

A timing side-channel vulnerability has been discovered in the opencryptoki package while processing RSA PKCS#1 v1.5 padded ciphertexts. This flaw could potentially enable unauthorized RSA ciphertext decryption or signing, even without access to the corresponding private key.

BBOT's unarchive module could be abused by supplying malicious archives files and when extracted can then perform an arbitrary file write, resulting in remote code execution.
