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-2020-25862 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-2020-25828 2 Fedoraproject, Mediawiki 2 Fedora, Mediawiki 2023-11-07 4.3 MEDIUM 6.1 MEDIUM
An issue was discovered in MediaWiki before 1.31.10 and 1.32.x through 1.34.x before 1.34.4. The non-jqueryMsg version of mw.message().parse() doesn't escape HTML. This affects both message contents (which are generally safe) and the parameters (which can be based on user input). (When jqueryMsg is loaded, it correctly accepts only whitelisted tags in message contents, and escapes all parameters. Situations with an unloaded jqueryMsg are rare in practice, but can for example occur for Special:SpecialPages on a wiki with no extensions installed.)
CVE-2020-25827 2 Fedoraproject, Mediawiki 2 Fedora, Mediawiki 2023-11-07 5.0 MEDIUM 7.5 HIGH
An issue was discovered in the OATHAuth extension in MediaWiki before 1.31.10 and 1.32.x through 1.34.x before 1.34.4. For Wikis using OATHAuth on a farm/cluster (such as via CentralAuth), rate limiting of OATH tokens is only done on a single site level. Thus, multiple requests can be made across many wikis/sites concurrently.
CVE-2020-25815 2 Fedoraproject, Mediawiki 2 Fedora, Mediawiki 2023-11-07 4.3 MEDIUM 6.1 MEDIUM
An issue was discovered in MediaWiki 1.32.x through 1.34.x before 1.34.4. LogEventList::getFiltersDesc is insecurely using message text to build options names for an HTML multi-select field. The relevant code should use escaped() instead of text().
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-2020-25813 2 Fedoraproject, Mediawiki 2 Fedora, Mediawiki 2023-11-07 5.0 MEDIUM 5.3 MEDIUM
In MediaWiki before 1.31.10 and 1.32.x through 1.34.x before 1.34.4, Special:UserRights exposes the existence of hidden users.
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-2020-25713 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-2020-25710 4 Debian, Fedoraproject, Openldap and 1 more 7 Debian Linux, Fedora, Openldap and 4 more 2023-11-07 5.0 MEDIUM 7.5 HIGH
A flaw was found in OpenLDAP in versions before 2.4.56. This flaw allows an attacker who sends a malicious packet processed by OpenLDAP to force a failed assertion in csnNormalize23(). The highest threat from this vulnerability is to system availability.
CVE-2020-25703 2 Fedoraproject, Moodle 2 Fedora, Moodle 2023-11-07 5.0 MEDIUM 5.3 MEDIUM
The participants table download in Moodle always included user emails, but should have only done so when users' emails are not hidden. Versions affected: 3.9 to 3.9.2, 3.8 to 3.8.5 and 3.7 to 3.7.8. This is fixed in moodle 3.9.3, 3.8.6, 3.7.9, and 3.10.
CVE-2020-25702 2 Fedoraproject, Moodle 2 Fedora, Moodle 2023-11-07 4.3 MEDIUM 6.1 MEDIUM
In Moodle, it was possible to include JavaScript when re-naming content bank items. Versions affected: 3.9 to 3.9.2. This is fixed in moodle 3.9.3 and 3.10.
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-2020-25700 2 Fedoraproject, Moodle 2 Fedora, Moodle 2023-11-07 4.0 MEDIUM 6.5 MEDIUM
In moodle, some database module web services allowed students to add entries within groups they did not belong to. 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 3.8.6, 3.7.9, 3.5.15, and 3.10.
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-2020-25698 2 Fedoraproject, Moodle 2 Fedora, Moodle 2023-11-07 5.0 MEDIUM 7.5 HIGH
Users' enrollment capabilities were not being sufficiently checked in Moodle when they are restored into an existing course. This could lead to them unenrolling users without having permission to do so. Versions affected: 3.5 to 3.5.14, 3.7 to 3.7.8, 3.8 to 3.8.5, 3.9 to 3.9.2 and earlier unsupported versions. Fixed in 3.9.3, 3.8.6, 3.7.9, 3.5.15, and 3.10.
CVE-2020-25693 2 Cimg, Fedoraproject 2 Cimg, Fedora 2023-11-07 5.8 MEDIUM 8.1 HIGH
A flaw was found in CImg in versions prior to 2.9.3. Integer overflows leading to heap buffer overflows in load_pnm() can be triggered by a specially crafted input file processed by CImg, which can lead to an impact to application availability or data integrity.
CVE-2020-25687 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. This flaw allows a remote attacker, who can create valid DNS replies, 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 sort_rrset() and cause a crash in dnsmasq, resulting in a denial of service. The highest threat from this vulnerability is to system availability.
CVE-2020-25686 4 Arista, Debian, Fedoraproject and 1 more 4 Eos, Debian Linux, Fedora and 1 more 2023-11-07 4.3 MEDIUM 3.7 LOW
A flaw was found in dnsmasq before version 2.83. When receiving a query, dnsmasq does not check for an existing pending request for the same name and forwards a new request. By default, a maximum of 150 pending queries can be sent to upstream servers, so there can be at most 150 queries for the same name. This flaw allows an off-path attacker on the network to substantially reduce the number of attempts that it would have to perform to forge a reply and have it accepted by dnsmasq. This issue is mentioned in the "Birthday Attacks" section of RFC5452. If chained with CVE-2020-25684, the attack complexity of a successful attack is reduced. The highest threat from this vulnerability is to data integrity.
CVE-2020-25685 4 Arista, Debian, Fedoraproject and 1 more 4 Eos, Debian Linux, Fedora and 1 more 2023-11-07 4.3 MEDIUM 3.7 LOW
A flaw was found in dnsmasq before version 2.83. When getting a reply from a forwarded query, dnsmasq checks in forward.c:reply_query(), which is the forwarded query that matches the reply, by only using a weak hash of the query name. Due to the weak hash (CRC32 when dnsmasq is compiled without DNSSEC, SHA-1 when it is) this flaw allows an off-path attacker to find several different domains all having the same hash, substantially reducing the number of attempts they would have to perform to forge a reply and get it accepted by dnsmasq. This is in contrast with RFC5452, which specifies that the query name is one of the attributes of a query that must be used to match a reply. This flaw could be abused to perform a DNS Cache Poisoning attack. If chained with CVE-2020-25684 the attack complexity of a successful attack is reduced. The highest threat from this vulnerability is to data integrity.
