CVE-2020-26558 5 Bluetooth, Debian, Fedoraproject and 2 more 34 Bluetooth Core Specification, Debian Linux, Fedora and 31 more 2023-11-07 4.3 MEDIUM 4.2 MEDIUM
Bluetooth LE and BR/EDR secure pairing in Bluetooth Core Specification 2.1 through 5.2 may permit a nearby man-in-the-middle attacker to identify the Passkey used during pairing (in the Passkey authentication procedure) by reflection of the public key and the authentication evidence of the initiating device, potentially permitting this attacker to complete authenticated pairing with the responding device using the correct Passkey for the pairing session. The attack methodology determines the Passkey value one bit at a time.
CVE-2020-26892 2 Fedoraproject, Linuxfoundation 2 Fedora, Nats-server 2023-11-07 7.5 HIGH 9.8 CRITICAL
The JWT library in NATS nats-server before 2.1.9 has Incorrect Access Control because of how expired credentials are handled.
CVE-2020-26575 4 Debian, Fedoraproject, Oracle and 1 more 5 Debian Linux, Fedora, Zfs Storage Appliance and 2 more 2023-11-07 5.0 MEDIUM 7.5 HIGH
In Wireshark through 3.2.7, the Facebook Zero Protocol (aka FBZERO) dissector could enter an infinite loop. This was addressed in epan/dissectors/packet-fbzero.c by correcting the implementation of offset advancement.
CVE-2020-25814 2 Fedoraproject, Mediawiki 2 Fedora, Mediawiki 2023-11-07 4.3 MEDIUM 6.1 MEDIUM
In MediaWiki before 1.31.10 and 1.32.x through 1.34.x before 1.34.4, XSS related to jQuery can occur. The attacker creates a message with [javascript:payload xss] and turns it into a jQuery object with mw.message().parse(). The expected result is that the jQuery object does not contain an <a> tag (or it does not have a href attribute, or it's empty, etc.). The actual result is that the object contains an <a href ="javascript... that executes when clicked.
CVE-2020-25812 2 Fedoraproject, Mediawiki 2 Fedora, Mediawiki 2023-11-07 4.3 MEDIUM 6.1 MEDIUM
An issue was discovered in MediaWiki 1.34.x before 1.34.4. On Special:Contributions, the NS filter uses unescaped messages as keys in the option key for an HTMLForm specifier. This is vulnerable to a mild XSS if one of those messages is changed to include raw HTML.
CVE-2020-24654 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2023-11-07 4.3 MEDIUM 3.3 LOW
In KDE Ark before 20.08.1, a crafted TAR archive with symlinks can install files outside the extraction directory, as demonstrated by a write operation to a user's home directory.
CVE-2020-25682 3 Debian, Fedoraproject, Thekelleys 3 Debian Linux, Fedora, Dnsmasq 2023-11-07 8.3 HIGH 8.1 HIGH
A flaw was found in dnsmasq before 2.83. A buffer overflow vulnerability was discovered in the way dnsmasq extract names from DNS packets before validating them with DNSSEC data. An attacker on the network, who can create valid DNS replies, could use this flaw to cause an overflow with arbitrary data in a heap-allocated memory, possibly executing code on the machine. The flaw is in the rfc1035.c:extract_name() function, which writes data to the memory pointed by name assuming MAXDNAME*2 bytes are available in the buffer. However, in some code execution paths, it is possible extract_name() gets passed an offset from the base buffer, thus reducing, in practice, the number of available bytes that can be written in the buffer. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2020-24584 4 Canonical, Djangoproject, Fedoraproject and 1 more 4 Ubuntu Linux, Django, Fedora and 1 more 2023-11-07 5.0 MEDIUM 7.5 HIGH
An issue was discovered in Django 2.2 before 2.2.16, 3.0 before 3.0.10, and 3.1 before 3.1.1 (when Python 3.7+ is used). The intermediate-level directories of the filesystem cache had the system's standard umask rather than 0o077.
CVE-2020-25713 3 Debian, Fedoraproject, Librdf 3 Debian Linux, Fedora, Raptor Rdf Syntax Library 2023-11-07 4.0 MEDIUM 6.5 MEDIUM
A malformed input file can lead to a segfault due to an out of bounds array access in raptor_xml_writer_start_element_common.
CVE-2020-24583 4 Canonical, Djangoproject, Fedoraproject and 1 more 4 Ubuntu Linux, Django, Fedora and 1 more 2023-11-07 5.0 MEDIUM 7.5 HIGH
An issue was discovered in Django 2.2 before 2.2.16, 3.0 before 3.0.10, and 3.1 before 3.1.1 (when Python 3.7+ is used). FILE_UPLOAD_DIRECTORY_PERMISSIONS mode was not applied to intermediate-level directories created in the process of uploading files. It was also not applied to intermediate-level collected static directories when using the collectstatic management command.
CVE-2020-25866 4 Fedoraproject, Opensuse, Oracle and 1 more 4 Fedora, Leap, Zfs Storage Appliance Kit and 1 more 2023-11-07 5.0 MEDIUM 7.5 HIGH
In Wireshark 3.2.0 to 3.2.6 and 3.0.0 to 3.0.13, the BLIP protocol dissector has a NULL pointer dereference because a buffer was sized for compressed (not uncompressed) messages. This was addressed in epan/dissectors/packet-blip.c by allowing reasonable compression ratios and rejecting ZIP bombs.
CVE-2020-27171 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2023-11-07 3.6 LOW 6.0 MEDIUM
An issue was discovered in the Linux kernel before 5.11.8. kernel/bpf/verifier.c has an off-by-one error (with a resultant integer underflow) affecting out-of-bounds speculation on pointer arithmetic, leading to side-channel attacks that defeat Spectre mitigations and obtain sensitive information from kernel memory, aka CID-10d2bb2e6b1d.
CVE-2020-25632 4 Fedoraproject, Gnu, Netapp and 1 more 8 Fedora, Grub2, Ontap Select Deploy Administration Utility and 5 more 2023-11-07 7.2 HIGH 8.2 HIGH
A flaw was found in grub2 in versions prior to 2.06. The rmmod implementation allows the unloading of a module used as a dependency without checking if any other dependent module is still loaded leading to a use-after-free scenario. This could allow arbitrary code to be executed or a bypass of Secure Boot protections. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2020-25683 3 Debian, Fedoraproject, Thekelleys 3 Debian Linux, Fedora, Dnsmasq 2023-11-07 7.1 HIGH 5.9 MEDIUM
A flaw was found in dnsmasq before version 2.83. A heap-based buffer overflow was discovered in dnsmasq when DNSSEC is enabled and before it validates the received DNS entries. A remote attacker, who can create valid DNS replies, could use this flaw to cause an overflow in a heap-allocated memory. This flaw is caused by the lack of length checks in rfc1035.c:extract_name(), which could be abused to make the code execute memcpy() with a negative size in get_rdata() and cause a crash in dnsmasq, resulting in a denial of service. The highest threat from this vulnerability is to system availability.
CVE-2020-25211 3 Debian, Fedoraproject, Linux 3 Debian Linux, Fedora, Linux Kernel 2023-11-07 3.6 LOW 6.0 MEDIUM
In the Linux kernel through 5.8.7, local attackers able to inject conntrack netlink configuration could overflow a local buffer, causing crashes or triggering use of incorrect protocol numbers in ctnetlink_parse_tuple_filter in net/netfilter/nf_conntrack_netlink.c, aka CID-1cc5ef91d2ff.
CVE-2020-25651 3 Debian, Fedoraproject, Spice-space 3 Debian Linux, Fedora, Spice-vdagent 2023-11-07 3.3 LOW 6.4 MEDIUM
A flaw was found in the SPICE file transfer protocol. File data from the host system can end up in full or in parts in the client connection of an illegitimate local user in the VM system. Active file transfers from other users could also be interrupted, resulting in a denial of service. The highest threat from this vulnerability is to data confidentiality as well as system availability. This flaw affects spice-vdagent versions 0.20 and prior.
CVE-2020-27638 3 Debian, Fastd Project, Fedoraproject 3 Debian Linux, Fastd, Fedora 2023-11-07 5.0 MEDIUM 7.5 HIGH
receive.c in fastd before v21 allows denial of service (assertion failure) when receiving packets with an invalid type code.
CVE-2020-25097 4 Debian, Fedoraproject, Netapp and 1 more 4 Debian Linux, Fedora, Cloud Manager and 1 more 2023-11-07 5.0 MEDIUM 8.6 HIGH
An issue was discovered in Squid through 4.13 and 5.x through 5.0.4. Due to improper input validation, it allows a trusted client to perform HTTP Request Smuggling and access services otherwise forbidden by the security controls. This occurs for certain uri_whitespace configuration settings.
CVE-2020-24661 2 Fedoraproject, Gnome 2 Fedora, Geary 2023-11-07 2.6 LOW 5.9 MEDIUM
GNOME Geary before 3.36.3 mishandles pinned TLS certificate verification for IMAP and SMTP services using invalid TLS certificates (e.g., self-signed certificates) when the client system is not configured to use a system-provided PKCS#11 store. This allows a meddler in the middle to present a different invalid certificate to intercept incoming and outgoing mail.
CVE-2020-26797 2 Fedoraproject, Mediaarea 2 Fedora, Mediainfo 2023-11-07 5.0 MEDIUM 7.5 HIGH
Mediainfo before version 20.08 has a heap buffer overflow vulnerability via MediaInfoLib::File_Gxf::ChooseParser_ChannelGrouping.
