CVE-2020-25862 5 Debian, Fedoraproject, Opensuse and 2 more 5 Debian Linux, Fedora, Leap and 2 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 TCP dissector could crash. This was addressed in epan/dissectors/packet-tcp.c by changing the handling of the invalid 0xFFFF checksum.
CVE-2020-26421 4 Debian, Fedoraproject, Oracle and 1 more 4 Debian Linux, Fedora, Zfs Storage Appliance Kit and 1 more 2023-11-07 5.0 MEDIUM 5.3 MEDIUM
Crash in USB HID protocol dissector and possibly other dissectors in Wireshark 3.4.0 and 3.2.0 to 3.2.8 allows denial of service via packet injection or crafted capture file.
CVE-2020-26519 3 Artifex, Debian, Fedoraproject 3 Mupdf, Debian Linux, Fedora 2023-11-07 4.3 MEDIUM 5.5 MEDIUM
Artifex MuPDF before 1.18.0 has a heap based buffer over-write when parsing JBIG2 files allowing attackers to cause a denial of service.
CVE-2020-27675 3 Debian, Fedoraproject, Linux 3 Debian Linux, Fedora, Linux Kernel 2023-11-07 4.7 MEDIUM 4.7 MEDIUM
An issue was discovered in the Linux kernel through 5.9.1, as used with Xen through 4.14.x. drivers/xen/events/events_base.c allows event-channel removal during the event-handling loop (a race condition). This can cause a use-after-free or NULL pointer dereference, as demonstrated by a dom0 crash via events for an in-reconfiguration paravirtualized device, aka CID-073d0552ead5.
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-2020-24606 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-2020-25596 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-2020-25696 2 Debian, Postgresql 2 Debian Linux, Postgresql 2023-11-07 7.6 HIGH 7.5 HIGH
A flaw was found in the psql interactive terminal of PostgreSQL in versions before 13.1, before 12.5, before 11.10, before 10.15, before 9.6.20 and before 9.5.24. If an interactive psql session uses \gset when querying a compromised server, the attacker can execute arbitrary code as the operating system account running psql. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
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-2020-25706 2 Cacti, Debian 2 Cacti, Debian Linux 2023-11-07 4.3 MEDIUM 6.1 MEDIUM
A cross-site scripting (XSS) vulnerability exists in templates_import.php (Cacti 1.2.13) due to Improper escaping of error message during template import preview in the xml_path field
CVE-2020-1935 6 Apache, Canonical, Debian and 3 more 20 Tomcat, Ubuntu Linux, Debian Linux and 17 more 2023-11-07 5.8 MEDIUM 4.8 MEDIUM
In Apache Tomcat 9.0.0.M1 to 9.0.30, 8.5.0 to 8.5.50 and 7.0.0 to 7.0.99 the HTTP header parsing code used an approach to end-of-line parsing that allowed some invalid HTTP headers to be parsed as valid. This led to a possibility of HTTP Request Smuggling if Tomcat was located behind a reverse proxy that incorrectly handled the invalid Transfer-Encoding header in a particular manner. Such a reverse proxy is considered unlikely.
CVE-2020-1711 4 Debian, Opensuse, Qemu and 1 more 5 Debian Linux, Leap, Qemu and 2 more 2023-11-07 6.0 MEDIUM 6.0 MEDIUM
An out-of-bounds heap buffer access flaw was found in the way the iSCSI Block driver in QEMU versions 2.12.0 before 4.2.1 handled a response coming from an iSCSI server while checking the status of a Logical Address Block (LBA) in an iscsi_co_block_status() routine. A remote user could use this flaw to crash the QEMU process, resulting in a denial of service or potential execution of arbitrary code with privileges of the QEMU process on the host.
CVE-2020-1983 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2023-11-07 2.1 LOW 6.5 MEDIUM
A use after free vulnerability in ip_reass() in ip_input.c of libslirp 4.2.0 and prior releases allows crafted packets to cause a denial of service.
CVE-2020-24386 3 Debian, Dovecot, Fedoraproject 3 Debian Linux, Dovecot, Fedora 2023-11-07 4.9 MEDIUM 6.8 MEDIUM
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-2020-22020 2 Debian, Ffmpeg 2 Debian Linux, Ffmpeg 2023-11-07 4.3 MEDIUM 6.5 MEDIUM
Buffer Overflow vulnerability in FFmpeg 4.2 in the build_diff_map function in libavfilter/vf_fieldmatch.c, which could let a remote malicious user cause a Denial of Service.
CVE-2020-22054 2 Debian, Ffmpeg 2 Debian Linux, Ffmpeg 2023-11-07 4.3 MEDIUM 6.5 MEDIUM
A Denial of Service vulnerability exists in FFmpeg 4.2 due to a memory leak in the av_dict_set function in dict.c.
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'.
CVE-2020-1957 2 Apache, Debian 2 Shiro, Debian Linux 2023-11-07 7.5 HIGH 9.8 CRITICAL
Apache Shiro before 1.5.2, when using Apache Shiro with Spring dynamic controllers, a specially crafted request may cause an authentication bypass.
