CVE-2019-7305 3 Canonical, Debian, Extplorer 3 Ubuntu Linux, Debian Linux, Extplorer 2021-09-13 7.5 HIGH 9.8 CRITICAL
Information Exposure vulnerability in eXtplorer makes the /usr/ and /etc/extplorer/ system directories world-accessible over HTTP. Introduced in the Makefile patch file debian/patches/debian-changes-2.1.0b6+dfsg-1 or debian/patches/adds-a-makefile.patch, this can lead to data leakage, information disclosure and potentially remote code execution on the web server. This issue affects all versions of eXtplorer in Ubuntu and Debian
CVE-2017-12629 4 Apache, Canonical, Debian and 1 more 5 Solr, Ubuntu Linux, Debian Linux and 2 more 2021-08-17 7.5 HIGH 9.8 CRITICAL
Remote code execution occurs in Apache Solr before 7.1 with Apache Lucene before 7.1 by exploiting XXE in conjunction with use of a Config API add-listener command to reach the RunExecutableListener class. Elasticsearch, although it uses Lucene, is NOT vulnerable to this. Note that the XML external entity expansion vulnerability occurs in the XML Query Parser which is available, by default, for any query request with parameters deftype=xmlparser and can be exploited to upload malicious data to the /upload request handler or as Blind XXE using ftp wrapper in order to read arbitrary local files from the Solr server. Note also that the second vulnerability relates to remote code execution using the RunExecutableListener available on all affected versions of Solr.
CVE-2017-7481 3 Canonical, Debian, Redhat 10 Ubuntu Linux, Debian Linux, Ansible Engine and 7 more 2021-08-04 7.5 HIGH 9.8 CRITICAL
Ansible before versions 2.3.1.0 and 2.4.0.0 fails to properly mark lookup-plugin results as unsafe. If an attacker could control the results of lookup() calls, they could inject Unicode strings to be parsed by the jinja2 templating system, resulting in code execution. By default, the jinja2 templating language is now marked as 'unsafe' and is not evaluated.
CVE-2018-17963 4 Canonical, Debian, Qemu and 1 more 6 Ubuntu Linux, Debian Linux, Qemu and 3 more 2021-08-04 7.5 HIGH 9.8 CRITICAL

CVE-2019-3464 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2021-07-21 7.5 HIGH 9.8 CRITICAL
Insufficient sanitization of environment variables passed to rsync can bypass the restrictions imposed by rssh, a restricted shell that should restrict users to perform only rsync operations, resulting in the execution of arbitrary shell commands.
CVE-2019-9848 3 Canonical, Fedoraproject, Libreoffice 3 Ubuntu Linux, Fedora, Libreoffice 2021-07-21 7.5 HIGH 9.8 CRITICAL
LibreOffice has a feature where documents can specify that pre-installed scripts can be executed on various document events such as mouse-over, etc. LibreOffice is typically also bundled with LibreLogo, a programmable turtle vector graphics script, which can be manipulated into executing arbitrary python commands. By using the document event feature to trigger LibreLogo to execute python contained within a document a malicious document could be constructed which would execute arbitrary python commands silently without warning. In the fixed versions, LibreLogo cannot be called from a document event handler. This issue affects: Document Foundation LibreOffice versions prior to 6.2.5.
CVE-2020-6831 4 Canonical, Debian, Mozilla and 1 more 6 Ubuntu Linux, Debian Linux, Firefox and 3 more 2021-07-21 7.5 HIGH 9.8 CRITICAL

CVE-2019-3822 7 Canonical, Debian, Haxx and 4 more 16 Ubuntu Linux, Debian Linux, Libcurl and 13 more 2021-06-15 7.5 HIGH 9.8 CRITICAL
libcurl versions from 7.36.0 to before 7.64.0 are vulnerable to a stack-based buffer overflow. The function creating an outgoing NTLM type-3 header (`lib/vauth/ntlm.c:Curl_auth_create_ntlm_type3_message()`), generates the request HTTP header contents based on previously received data. The check that exists to prevent the local buffer from getting overflowed is implemented wrongly (using unsigned math) and as such it does not prevent the overflow from happening. This output data can grow larger than the local buffer if very large 'nt response' data is extracted from a previous NTLMv2 header provided by the malicious or broken HTTP server. Such a 'large value' needs to be around 1000 bytes or more. The actual payload data copied to the target buffer comes from the NTLMv2 type-2 response header.
CVE-2019-17539 3 Canonical, Debian, Ffmpeg 3 Ubuntu Linux, Debian Linux, Ffmpeg 2021-06-10 7.5 HIGH 9.8 CRITICAL

CVE-2020-11945 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2021-03-17 7.5 HIGH 9.8 CRITICAL
An issue was discovered in Squid before 5.0.2. A remote attacker can replay a sniffed Digest Authentication nonce to gain access to resources that are otherwise forbidden. This occurs because the attacker can overflow the nonce reference counter (a short integer). Remote code execution may occur if the pooled token credentials are freed (instead of replayed as valid credentials).
CVE-2016-1585 1 Canonical 1 Apparmor 2021-02-25 7.5 HIGH 9.8 CRITICAL
In all versions of AppArmor mount rules are accidentally widened when compiled.
CVE-2016-2148 3 Busybox, Canonical, Debian 3 Busybox, Ubuntu Linux, Debian Linux 2021-02-22 7.5 HIGH 9.8 CRITICAL

CVE-2019-12519 4 Canonical, Debian, Opensuse and 1 more 4 Ubuntu Linux, Debian Linux, Leap and 1 more 2021-02-11 7.5 HIGH 9.8 CRITICAL
An issue was discovered in Squid through 4.7. When handling the tag esi:when when ESI is enabled, Squid calls ESIExpression::Evaluate. This function uses a fixed stack buffer to hold the expression while it's being evaluated. When processing the expression, it could either evaluate the top of the stack, or add a new member to the stack. When adding a new member, there is no check to ensure that the stack won't overflow.
CVE-2019-12524 3 Canonical, Debian, Squid-cache 3 Ubuntu Linux, Debian Linux, Squid 2021-02-09 7.5 HIGH 9.8 CRITICAL
An issue was discovered in Squid through 4.7. When handling requests from users, Squid checks its rules to see if the request should be denied. Squid by default comes with rules to block access to the Cache Manager, which serves detailed server information meant for the maintainer. This rule is implemented via url_regex. The handler for url_regex rules URL decodes an incoming request. This allows an attacker to encode their URL to bypass the url_regex check, and gain access to the blocked resource.
CVE-2017-17480 3 Canonical, Debian, Uclouvain 3 Ubuntu Linux, Debian Linux, Openjpeg 2021-02-03 7.5 HIGH 9.8 CRITICAL
