| CVE-2020-26521 | 2 Fedoraproject, Linuxfoundation | 2 Fedora, Nats-server | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
| The JWT library in NATS nats-server before 2.1.9 allows a denial of service (a nil dereference in Go code). | |||||
| CVE-2020-25863 | 5 Debian, Fedoraproject, Opensuse and 2 more | 6 Debian Linux, Fedora, Leap and 3 more | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
| In Wireshark 3.2.0 to 3.2.6, 3.0.0 to 3.0.13, and 2.6.0 to 2.6.20, the MIME Multipart dissector could crash. This was addressed in epan/dissectors/packet-multipart.c by correcting the deallocation of invalid MIME parts. | |||||
| CVE-2020-25597 | 2 Fedoraproject, Xen | 2 Fedora, Xen | 2023-11-07 | 6.1 MEDIUM | 6.5 MEDIUM |
| An issue was discovered in Xen through 4.14.x. There is mishandling of the constraint that once-valid event channels may not turn invalid. Logic in the handling of event channel operations in Xen assumes that an event channel, once valid, will not become invalid over the life time of a guest. However, operations like the resetting of all event channels may involve decreasing one of the bounds checked when determining validity. This may lead to bug checks triggering, crashing the host. An unprivileged guest may be able to crash Xen, leading to a Denial of Service (DoS) for the entire system. All Xen versions from 4.4 onwards are vulnerable. Xen versions 4.3 and earlier are not vulnerable. Only systems with untrusted guests permitted to create more than the default number of event channels are vulnerable. This number depends on the architecture and type of guest. For 32-bit x86 PV guests, this is 1023; for 64-bit x86 PV guests, and for all ARM guests, this number is 4095. Systems where untrusted guests are limited to fewer than this number are not vulnerable. Note that xl and libxl limit max_event_channels to 1023 by default, so systems using exclusively xl, libvirt+libxl, or their own toolstack based on libxl, and not explicitly setting max_event_channels, are not vulnerable. | |||||
| CVE-2020-24606 | 5 Canonical, Debian, Fedoraproject and 2 more | 5 Ubuntu Linux, Debian Linux, Fedora and 2 more | 2023-11-07 | 7.1 HIGH | 7.5 HIGH |
| Squid before 4.13 and 5.x before 5.0.4 allows a trusted peer to perform Denial of Service by consuming all available CPU cycles during handling of a crafted Cache Digest response message. This only occurs when cache_peer is used with the cache digests feature. The problem exists because peerDigestHandleReply() livelocking in peer_digest.cc mishandles EOF. | |||||
| CVE-2020-25699 | 2 Fedoraproject, Moodle | 2 Fedora, Moodle | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
| In moodle, insufficient capability checks could lead to users with the ability to course restore adding additional capabilities to roles within that course. Versions affected: 3.9 to 3.9.2, 3.8 to 3.8.5, 3.7 to 3.7.8, 3.5 to 3.5.14 and earlier unsupported versions. This is fixed in moodle 3.9.3, 3.8.6, 3.7.9, 3.5.15, and 3.10. | |||||
| CVE-2020-25596 | 4 Debian, Fedoraproject, Opensuse and 1 more | 4 Debian Linux, Fedora, Leap and 1 more | 2023-11-07 | 2.1 LOW | 5.5 MEDIUM |
| An issue was discovered in Xen through 4.14.x. x86 PV guest kernels can experience denial of service via SYSENTER. The SYSENTER instruction leaves various state sanitization activities to software. One of Xen's sanitization paths injects a #GP fault, and incorrectly delivers it twice to the guest. This causes the guest kernel to observe a kernel-privilege #GP fault (typically fatal) rather than a user-privilege #GP fault (usually converted into SIGSEGV/etc.). Malicious or buggy userspace can crash the guest kernel, resulting in a VM Denial of Service. All versions of Xen from 3.2 onwards are vulnerable. Only x86 systems are vulnerable. ARM platforms are not vulnerable. Only x86 systems that support the SYSENTER instruction in 64bit mode are vulnerable. This is believed to be Intel, Centaur, and Shanghai CPUs. AMD and Hygon CPUs are not believed to be vulnerable. Only x86 PV guests can exploit the vulnerability. x86 PVH / HVM guests cannot exploit the vulnerability. | |||||
| CVE-2020-25601 | 4 Debian, Fedoraproject, Opensuse and 1 more | 4 Debian Linux, Fedora, Leap and 1 more | 2023-11-07 | 4.9 MEDIUM | 5.5 MEDIUM |
| An issue was discovered in Xen through 4.14.x. There is a lack of preemption in evtchn_reset() / evtchn_destroy(). In particular, the FIFO event channel model allows guests to have a large number of event channels active at a time. Closing all of these (when resetting all event channels or when cleaning up after the guest) may take extended periods of time. So far, there was no arrangement for preemption at suitable intervals, allowing a CPU to spend an almost unbounded amount of time in the processing of these operations. Malicious or buggy guest kernels can mount a Denial of Service (DoS) attack affecting the entire system. All Xen versions are vulnerable in principle. Whether versions 4.3 and older are vulnerable depends on underlying hardware characteristics. | |||||
| CVE-2020-25701 | 2 Fedoraproject, Moodle | 2 Fedora, Moodle | 2023-11-07 | 5.0 MEDIUM | 5.3 MEDIUM |
| If the upload course tool in Moodle was used to delete an enrollment method which did not exist or was not already enabled, the tool would erroneously enable that enrollment method. This could lead to unintended users gaining access to the course. Versions affected: 3.9 to 3.9.2, 3.8 to 3.8.5, 3.7 to 3.7.8, 3.5 to 3.5.14 and earlier unsupported versions. This is fixed in moodle 3.9.3, 3.8.6, 3.7.9, 3.5.15, and 3.10. | |||||
| CVE-2020-26116 | 7 Canonical, Debian, Fedoraproject and 4 more | 9 Ubuntu Linux, Debian Linux, Fedora and 6 more | 2023-11-07 | 6.4 MEDIUM | 7.2 HIGH |
| http.client in Python 3.x before 3.5.10, 3.6.x before 3.6.12, 3.7.x before 3.7.9, and 3.8.x before 3.8.5 allows CRLF injection if the attacker controls the HTTP request method, as demonstrated by inserting CR and LF control characters in the first argument of HTTPConnection.request. | |||||
| CVE-2020-25660 | 2 Fedoraproject, Redhat | 4 Fedora, Ceph, Ceph Storage and 1 more | 2023-11-07 | 5.8 MEDIUM | 8.8 HIGH |
| A flaw was found in the Cephx authentication protocol in versions before 15.2.6 and before 14.2.14, where it does not verify Ceph clients correctly and is then vulnerable to replay attacks in Nautilus. This flaw allows an attacker with access to the Ceph cluster network to authenticate with the Ceph service via a packet sniffer and perform actions allowed by the Ceph service. This issue is a reintroduction of CVE-2018-1128, affecting the msgr2 protocol. The msgr 2 protocol is used for all communication except older clients that do not support the msgr2 protocol. The msgr1 protocol is not affected. The highest threat from this vulnerability is to confidentiality, integrity, and system availability. | |||||

| An issue was discovered in Dovecot before 2.3.13. By using IMAP IDLE, an authenticated attacker can trigger unhibernation via attacker-controlled parameters, leading to access to other users' email messages (and path disclosure). | |||||
| CVE-2020-1730 | 6 Canonical, Fedoraproject, Libssh and 3 more | 6 Ubuntu Linux, Fedora, Libssh and 3 more | 2023-11-07 | 5.0 MEDIUM | 5.3 MEDIUM |
| A flaw was found in libssh versions before 0.8.9 and before 0.9.4 in the way it handled AES-CTR (or DES ciphers if enabled) ciphers. The server or client could crash when the connection hasn't been fully initialized and the system tries to cleanup the ciphers when closing the connection. The biggest threat from this vulnerability is system availability. | |||||
| CVE-2020-24388 | 2 Fedoraproject, Yubico | 2 Fedora, Yubihsm-shell | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in the _send_secure_msg() function of yubihsm-shell through 2.0.2. The function does not validate the embedded length field of a message received from the device. This could lead to an oversized memcpy() call that will crash the running process. This could be used by an attacker to cause a denial of service. | |||||
| CVE-2020-24387 | 2 Fedoraproject, Yubico | 2 Fedora, Yubihsm-shell | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in the yh_create_session() function of yubihsm-shell through 2.0.2. The function does not explicitly check the returned session id from the device. An invalid session id would lead to out-of-bounds read and write operations in the session array. This could be used by an attacker to cause a denial of service attack. | |||||
| CVE-2020-17353 | 4 Debian, Fedoraproject, Lilypond and 1 more | 5 Debian Linux, Fedora, Lilypond and 2 more | 2023-11-07 | 7.5 HIGH | 9.8 CRITICAL |
| scm/define-stencil-commands.scm in LilyPond through 2.20.0, and 2.21.x through 2.21.4, when -dsafe is used, lacks restrictions on embedded-ps and embedded-svg, as demonstrated by including dangerous PostScript code. | |||||
| CVE-2020-1733 | 3 Debian, Fedoraproject, Redhat | 6 Debian Linux, Fedora, Ansible and 3 more | 2023-11-07 | 3.7 LOW | 5.0 MEDIUM |
| A race condition flaw was found in Ansible Engine 2.7.17 and prior, 2.8.9 and prior, 2.9.6 and prior when running a playbook with an unprivileged become user. When Ansible needs to run a module with become user, the temporary directory is created in /var/tmp. This directory is created with "umask 77 && mkdir -p <dir>"; this operation does not fail if the directory already exists and is owned by another user. An attacker could take advantage to gain control of the become user as the target directory can be retrieved by iterating '/proc/<pid>/cmdline'. | |||||
