Vulnerabilities (CVE)

An exploitable denial-of-service vulnerability exists in Systemd 245. A specially crafted DHCP FORCERENEW packet can cause a server running the DHCP client to be vulnerable to a DHCP ACK spoofing attack. An attacker can forge a pair of FORCERENEW and DCHP ACK packets to reconfigure the server.

EM-HTTP-Request 1.1.5 uses the library eventmachine in an insecure way that allows an attacker to perform a man-in-the-middle attack against users of the library. The hostname in a TLS server certificate is not verified.

SQLite through 3.32.0 has a segmentation fault in sqlite3ExprCodeTarget in expr.c.

SQLite through 3.32.0 has an integer overflow in sqlite3_str_vappendf in printf.c.

An issue was discovered in Docker Engine before 19.03.11. An attacker in a container, with the CAP_NET_RAW capability, can craft IPv6 router advertisements, and consequently spoof external IPv6 hosts, obtain sensitive information, or cause a denial of service.

The avatar feature in Grafana 3.0.1 through 7.0.1 has an SSRF Incorrect Access Control issue. This vulnerability allows any unauthenticated user/client to make Grafana send HTTP requests to any URL and return its result to the user/client. This can be used to gain information about the network that Grafana is running on. Furthermore, passing invalid URL objects could be used for DOS'ing Grafana via SegFault.

An issue was discovered in Django 2.2 before 2.2.13 and 3.0 before 3.0.7. In cases where a memcached backend does not perform key validation, passing malformed cache keys could result in a key collision, and potential data leakage.

libmariadb/mariadb_lib.c in MariaDB Connector/C before 3.1.8 does not properly validate the content of an OK packet received from a server. NOTE: although mariadb_lib.c was originally based on code shipped for MySQL, this issue does not affect any MySQL components supported by Oracle.

In Cacti before 1.2.11, auth_profile.php?action=edit allows CSRF for an admin email change.

In Cacti before 1.2.11, disabling a user account does not immediately invalidate any permissions granted to that account (e.g., permission to view logs).

In Wireshark 3.2.0 to 3.2.3, 3.0.0 to 3.0.10, and 2.6.0 to 2.6.16, the NFS dissector could crash. This was addressed in epan/dissectors/packet-nfs.c by preventing excessive recursion, such as for a cycle in the directory graph on a filesystem.

The VFIO PCI driver in the Linux kernel through 5.6.13 mishandles attempts to access disabled memory space.

A NULL pointer dereference in sanei_epson_net_read in SANE Backends before 1.0.30 allows a malicious device connected to the same local network as the victim to cause a denial of service, aka GHSL-2020-075.

OpenConnect 8.09 has a buffer overflow, causing a denial of service (application crash) or possibly unspecified other impact, via crafted certificate data to get_cert_name in gnutls.c.

ODF documents can contain forms to be filled out by the user. Similar to HTML forms, the contained form data can be submitted to a URI, for example, to an external web server. To create submittable forms, ODF implements the XForms W3C standard, which allows data to be submitted without the need for macros or other active scripting Prior to version 6.4.4 LibreOffice allowed forms to be submitted to any URI, including file: URIs, enabling form submissions to overwrite local files. User-interaction ... ODF documents can contain forms to be filled out by the user. Similar to HTML forms, the contained form data can be submitted to a URI, for example, to an external web server. To create submittable forms, ODF implements the XForms W3C standard, which allows data to be submitted without the need for macros or other active scripting Prior to version 6.4.4 LibreOffice allowed forms to be submitted to any URI, including file: URIs, enabling form submissions to overwrite local files. User-interaction is required to submit the form, but to avoid the possibility of malicious documents engineered to maximize the possibility of inadvertent user submission this feature has now been limited to http[s] URIs, removing the possibility to overwrite local files. This issue affects: The Document Foundation LibreOffice versions prior to 6.4.4.

LibreOffice has a 'stealth mode' in which only documents from locations deemed 'trusted' are allowed to retrieve remote resources. This mode is not the default mode, but can be enabled by users who want to disable LibreOffice's ability to include remote resources within a document. A flaw existed where remote graphic links loaded from docx documents were omitted from this protection prior to version 6.4.4. This issue affects: The Document Foundation LibreOffice versions prior to 6.4.4.

Exim through 4.93 has an out-of-bounds read in the SPA authenticator that could result in SPA/NTLM authentication bypass in auths/spa.c and auths/auth-spa.c.

An issue was discovered in the Linux kernel through 5.6.11. sg_write lacks an sg_remove_request call in a certain failure case, aka CID-83c6f2390040.

tcprewrite in Tcpreplay through 4.3.2 has a heap-based buffer over-read during a get_c operation. The issue is being triggered in the function get_ipv6_next() at common/get.c.

regcomp.c in Perl before 5.30.3 allows a buffer overflow via a crafted regular expression because of recursive S_study_chunk calls.

The Open Connectivity Foundation UPnP specification before 2020-04-17 does not forbid the acceptance of a subscription request with a delivery URL on a different network segment than the fully qualified event-subscription URL, aka the CallStranger issue.

Slurm 19.05.x before 19.05.7 and 20.02.x before 20.02.3, in the rare case where Message Aggregation is enabled, allows Authentication Bypass via an Alternate Path or Channel. A race condition allows a user to launch a process as an arbitrary user.

In Dovecot before 2.3.11.3, sending a specially formatted RPA request will crash the auth service because a length of zero is mishandled.

In Dovecot before 2.3.11.3, sending a specially formatted NTLM request will crash the auth service because of an out-of-bounds read.

macaron before 1.3.7 has an open redirect in the static handler, as demonstrated by the http://127.0.0.1:4000//example.com/ URL.

Unbound before 1.10.1 has an infinite loop via malformed DNS answers received from upstream servers.

Unbound before 1.10.1 has Insufficient Control of Network Message Volume, aka an "NXNSAttack" issue. This is triggered by random subdomains in the NSDNAME in NS records.

OpenDMARC through 1.3.2 and 1.4.x through 1.4.0-Beta1 has improper null termination in the function opendmarc_xml_parse that can result in a one-byte heap overflow in opendmarc_xml when parsing a specially crafted DMARC aggregate report. This can cause remote memory corruption when a '\0' byte overwrites the heap metadata of the next chunk and its PREV_INUSE flag.

In certain Red Hat packages for Grafana 6.x through 6.3.6, the configuration files /etc/grafana/grafana.ini and /etc/grafana/ldap.toml (which contain a secret_key and a bind_password) are world readable.

An information-disclosure flaw was found in Grafana through 6.7.3. The database directory /var/lib/grafana and database file /var/lib/grafana/grafana.db are world readable. This can result in exposure of sensitive information (e.g., cleartext or encrypted datasource passwords).

During RSA key generation, bignum implementations used a variation of the Binary Extended Euclidean Algorithm which entailed significantly input-dependent flow. This allowed an attacker able to perform electromagnetic-based side channel attacks to record traces leading to the recovery of the secret primes. *Note:* An unmodified Firefox browser does not generate RSA keys in normal operation and is not affected, but products built on top of it might. This vulnerability affects Firefox < 78.

OpenDMARC through 1.3.2 and 1.4.x allows attacks that inject authentication results to provide false information about the domain that originated an e-mail message. This is caused by incorrect parsing and interpretation of SPF/DKIM authentication results, as demonstrated by the example.net(.example.com substring.

An issue has been found in PowerDNS Recursor 4.1.0 through 4.3.0 where records in the answer section of a NXDOMAIN response lacking an SOA were not properly validated in SyncRes::processAnswer, allowing an attacker to bypass DNSSEC validation.

GNU Mailman 2.x before 2.1.30 uses the .obj extension for scrubbed application/octet-stream MIME parts. This behavior may contribute to XSS attacks against list-archive visitors, because an HTTP reply from an archive web server may lack a MIME type, and a web browser may perform MIME sniffing, conclude that the MIME type should have been text/html, and execute JavaScript code.

/options/mailman in GNU Mailman before 2.1.31 allows Arbitrary Content Injection.

In Dovecot before 2.3.11.3, uncontrolled recursion in submission, lmtp, and lda allows remote attackers to cause a denial of service (resource consumption) via a crafted e-mail message with deeply nested MIME parts.

CServer::SendMsg in engine/server/server.cpp in Teeworlds 0.7.x before 0.7.5 allows remote attackers to shut down the server.

SQLiteODBC 0.9996, as packaged for certain Linux distributions as 0.9996-4, has a race condition leading to root privilege escalation because any user can replace a /tmp/sqliteodbc$$ file with new contents that cause loading of an arbitrary library.

Apache XmlGraphics Commons 2.4 and earlier is vulnerable to server-side request forgery, caused by improper input validation by the XMPParser. By using a specially-crafted argument, an attacker could exploit this vulnerability to cause the underlying server to make arbitrary GET requests. Users should upgrade to 2.6 or later.

Apache HTTP server 2.4.32 to 2.4.44 mod_proxy_uwsgi info disclosure and possible RCE
