Уязвимость компонента HgDriver менеджера зависимостей для PHP Composer, связанная с внедрением или модификацией аргумента, позволяющая нарушителю получить доступ к конфиденциальным данным, нарушить их целостность, а также вызвать отказ в обслуживании

Composer is a dependency manager for PHP. URLs for Mercurial repositories in the root composer.json and package source download URLs are not sanitized correctly. Specifically crafted URL values allow code to be executed in the HgDriver if hg/Mercurial is installed on the system. The impact to Composer users directly is limited as the composer.json file is typically under their own control and source download URLs can only be supplied by third party Composer repositories they explicitly trust to download and execute source code from, e.g. Composer plugins. The main impact is to services passing user input to Composer, including Packagist.org and Private Packagist. This allowed users to trigger remote code execution. The vulnerability has been patched on Packagist.org and Private Packagist within 12h of receiving the initial vulnerability report and based on a review of logs, to the best of our knowledge, was not abused by anyone. Other services/tools using VcsRepository/VcsDriver or derivatives may also be vulnerable and should upgrade their composer/composer dependency immediately. Versions 1.10.22 and 2.0.13 include patches for this issue.

Уязвимость функции ext4_write_inline_data_end (fs/ext4/inline.c) ядра операционной системы Linux, позволяющая нарушителю оказать влияние на целостность, доступность и конфиденциальность данных

Уязвимость реализации функции check_map_func_compatibility() ядра операционных систем Linux, позволяющая нарушителю повысить свои привилегии

Уязвимость функции decode_data компонента drivers/net/hamradio/6pack.c ядра операционной системы Linux, позволяющая нарушителю получить доступ к конфиденциальным данным, нарушить их целостность, а также вызвать отказ в обслуживании

This vulnerability allows local attackers to escalate privileges on affected installations of Linux Kernel 5.14-rc3. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the handling of eBPF programs. The issue results from the lack of proper validation of user-supplied eBPF programs, which can result in a type confusion condition. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the kernel. Was ZDI-CAN-14689.

A race condition was discovered in ext4_write_inline_data_end in fs/ext4/inline.c in the ext4 subsystem in the Linux kernel through 5.13.13.

The decode_data function in drivers/net/hamradio/6pack.c in the Linux kernel before 5.13.13 has a slab out-of-bounds write. Input from a process that has the CAP_NET_ADMIN capability can lead to root access.

A flaw was found in the Linux kernel’s io_uring implementation. This flaw allows an attacker with a local account to corrupt system memory, crash the system or escalate privileges.

Уязвимость компонентов net.ParseIP, net.ParseCIDR языка программирования Go, позволяющая нарушителю оказать воздействие на целостность данных

Go before 1.17 does not properly consider extraneous zero characters at the beginning of an IP address octet, which (in some situations) allows attackers to bypass access control that is based on IP addresses, because of unexpected octal interpretation. This affects net.ParseIP and net.ParseCIDR.

In archive/zip in Go before 1.16.8 and 1.17.x before 1.17.1, a crafted archive header (falsely designating that many files are present) can cause a NewReader or OpenReader panic. NOTE: this issue exists because of an incomplete fix for CVE-2021-33196.

A session hijack risk was identified in the Shibboleth authentication plugin.

Insufficient capability checks made it possible for teachers to download users outside of their courses.

An authentication bypass risk was identified in the external database authentication functionality, due to a type juggling vulnerability.

Insufficient escaping of the LaTeX preamble made it possible for site administrators to read files available to the HTTP server system account.

It was possible for a student to view their quiz grade before it had been released, using a quiz web service.
