| CVE-2019-12781 | 4 Canonical, Debian, Djangoproject and 1 more | 6 Ubuntu Linux, Debian Linux, Django and 3 more | 2024-11-21 | N/A |
| An issue was discovered in Django 1.11 before 1.11.22, 2.1 before 2.1.10, and 2.2 before 2.2.3. An HTTP request is not redirected to HTTPS when the SECURE_PROXY_SSL_HEADER and SECURE_SSL_REDIRECT settings are used, and the proxy connects to Django via HTTPS. In other words, django.http.HttpRequest.scheme has incorrect behavior when a client uses HTTP. | ||||
| CVE-2019-12749 | 3 Canonical, Freedesktop, Redhat | 5 Ubuntu Linux, Dbus, Enterprise Linux and 2 more | 2024-11-21 | N/A |
| dbus before 1.10.28, 1.12.x before 1.12.16, and 1.13.x before 1.13.12, as used in DBusServer in Canonical Upstart in Ubuntu 14.04 (and in some, less common, uses of dbus-daemon), allows cookie spoofing because of symlink mishandling in the reference implementation of DBUS_COOKIE_SHA1 in the libdbus library. (This only affects the DBUS_COOKIE_SHA1 authentication mechanism.) A malicious client with write access to its own home directory could manipulate a ~/.dbus-keyrings symlink to cause a DBusServer with a different uid to read and write in unintended locations. In the worst case, this could result in the DBusServer reusing a cookie that is known to the malicious client, and treating that cookie as evidence that a subsequent client connection came from an attacker-chosen uid, allowing authentication bypass. | ||||
| CVE-2019-12614 | 5 Canonical, Fedoraproject, Linux and 2 more | 5 Ubuntu Linux, Fedora, Linux Kernel and 2 more | 2024-11-21 | 4.1 Medium |
| An issue was discovered in dlpar_parse_cc_property in arch/powerpc/platforms/pseries/dlpar.c in the Linux kernel through 5.1.6. There is an unchecked kstrdup of prop->name, which might allow an attacker to cause a denial of service (NULL pointer dereference and system crash). | ||||
| CVE-2019-12529 | 6 Canonical, Debian, Fedoraproject and 3 more | 6 Ubuntu Linux, Debian Linux, Fedora and 3 more | 2024-11-21 | 5.9 Medium |
| An issue was discovered in Squid 2.x through 2.7.STABLE9, 3.x through 3.5.28, and 4.x through 4.7. When Squid is configured to use Basic Authentication, the Proxy-Authorization header is parsed via uudecode. uudecode determines how many bytes will be decoded by iterating over the input and checking its table. The length is then used to start decoding the string. There are no checks to ensure that the length it calculates isn't greater than the input buffer. This leads to adjacent memory being decoded as well. An attacker would not be able to retrieve the decoded data unless the Squid maintainer had configured the display of usernames on error pages. | ||||
| CVE-2019-12528 | 6 Canonical, Debian, Fedoraproject and 3 more | 6 Ubuntu Linux, Debian Linux, Fedora and 3 more | 2024-11-21 | 7.5 High |
| An issue was discovered in Squid before 4.10. It allows a crafted FTP server to trigger disclosure of sensitive information from heap memory, such as information associated with other users' sessions or non-Squid processes. | ||||
| CVE-2019-12527 | 5 Canonical, Debian, Fedoraproject and 2 more | 8 Ubuntu Linux, Debian Linux, Fedora and 5 more | 2024-11-21 | 8.8 High |
| An issue was discovered in Squid 4.0.23 through 4.7. When checking Basic Authentication with HttpHeader::getAuth, Squid uses a global buffer to store the decoded data. Squid does not check that the decoded length isn't greater than the buffer, leading to a heap-based buffer overflow with user controlled data. | ||||
| CVE-2019-12526 | 6 Canonical, Debian, Fedoraproject and 3 more | 6 Ubuntu Linux, Debian Linux, Fedora and 3 more | 2024-11-21 | 9.8 Critical |
| An issue was discovered in Squid before 4.9. URN response handling in Squid suffers from a heap-based buffer overflow. When receiving data from a remote server in response to an URN request, Squid fails to ensure that the response can fit within the buffer. This leads to attacker controlled data overflowing in the heap. | ||||
| CVE-2019-12525 | 6 Canonical, Debian, Fedoraproject and 3 more | 6 Ubuntu Linux, Debian Linux, Fedora and 3 more | 2024-11-21 | 9.8 Critical |
| An issue was discovered in Squid 3.3.9 through 3.5.28 and 4.x through 4.7. When Squid is configured to use Digest authentication, it parses the header Proxy-Authorization. It searches for certain tokens such as domain, uri, and qop. Squid checks if this token's value starts with a quote and ends with one. If so, it performs a memcpy of its length minus 2. Squid never checks whether the value is just a single quote (which would satisfy its requirements), leading to a memcpy of its length minus 1. | ||||
| CVE-2019-12524 | 4 Canonical, Debian, Redhat and 1 more | 4 Ubuntu Linux, Debian Linux, Enterprise Linux and 1 more | 2024-11-21 | 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-2019-12523 | 6 Canonical, Debian, Fedoraproject and 3 more | 6 Ubuntu Linux, Debian Linux, Fedora and 3 more | 2024-11-21 | 9.1 Critical |
| An issue was discovered in Squid before 4.9. When handling a URN request, a corresponding HTTP request is made. This HTTP request doesn't go through the access checks that incoming HTTP requests go through. This causes all access checks to be bypassed and allows access to restricted HTTP servers, e.g., an attacker can connect to HTTP servers that only listen on localhost. | ||||
| CVE-2019-12521 | 5 Canonical, Debian, Opensuse and 2 more | 5 Ubuntu Linux, Debian Linux, Leap and 2 more | 2024-11-21 | 5.9 Medium |
| An issue was discovered in Squid through 4.7. When Squid is parsing ESI, it keeps the ESI elements in ESIContext. ESIContext contains a buffer for holding a stack of ESIElements. When a new ESIElement is parsed, it is added via addStackElement. addStackElement has a check for the number of elements in this buffer, but it's off by 1, leading to a Heap Overflow of 1 element. The overflow is within the same structure so it can't affect adjacent memory blocks, and thus just leads to a crash while processing. | ||||
| CVE-2019-12520 | 4 Canonical, Debian, Redhat and 1 more | 4 Ubuntu Linux, Debian Linux, Enterprise Linux and 1 more | 2024-11-21 | 7.5 High |
| An issue was discovered in Squid through 4.7 and 5. When receiving a request, Squid checks its cache to see if it can serve up a response. It does this by making a MD5 hash of the absolute URL of the request. If found, it servers the request. The absolute URL can include the decoded UserInfo (username and password) for certain protocols. This decoded info is prepended to the domain. This allows an attacker to provide a username that has special characters to delimit the domain, and treat the rest of the URL as a path or query string. An attacker could first make a request to their domain using an encoded username, then when a request for the target domain comes in that decodes to the exact URL, it will serve the attacker's HTML instead of the real HTML. On Squid servers that also act as reverse proxies, this allows an attacker to gain access to features that only reverse proxies can use, such as ESI. | ||||
| CVE-2019-12519 | 5 Canonical, Debian, Opensuse and 2 more | 7 Ubuntu Linux, Debian Linux, Leap and 4 more | 2024-11-21 | 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-2019-12450 | 6 Canonical, Debian, Fedoraproject and 3 more | 10 Ubuntu Linux, Debian Linux, Fedora and 7 more | 2024-11-21 | 9.8 Critical |
| file_copy_fallback in gio/gfile.c in GNOME GLib 2.15.0 through 2.61.1 does not properly restrict file permissions while a copy operation is in progress. Instead, default permissions are used. | ||||
| CVE-2019-12449 | 5 Canonical, Fedoraproject, Gnome and 2 more | 5 Ubuntu Linux, Fedora, Gvfs and 2 more | 2024-11-21 | 5.7 Medium |
| An issue was discovered in GNOME gvfs 1.29.4 through 1.41.2. daemon/gvfsbackendadmin.c mishandles a file's user and group ownership during move (and copy with G_FILE_COPY_ALL_METADATA) operations from admin:// to file:// URIs, because root privileges are unavailable. | ||||
| CVE-2019-12447 | 5 Canonical, Fedoraproject, Gnome and 2 more | 5 Ubuntu Linux, Fedora, Gvfs and 2 more | 2024-11-21 | 7.3 High |
| An issue was discovered in GNOME gvfs 1.29.4 through 1.41.2. daemon/gvfsbackendadmin.c mishandles file ownership because setfsuid is not used. | ||||
| CVE-2019-12436 | 2 Canonical, Samba | 2 Ubuntu Linux, Samba | 2024-11-21 | N/A |
| Samba 4.10.x before 4.10.5 has a NULL pointer dereference, leading to an AD DC LDAP server Denial of Service. This is related to an attacker using the paged search control. The attacker must have directory read access in order to attempt an exploit. | ||||
| CVE-2019-12418 | 7 Apache, Canonical, Debian and 4 more | 7 Tomcat, Ubuntu Linux, Debian Linux and 4 more | 2024-11-21 | 7.0 High |
| When Apache Tomcat 9.0.0.M1 to 9.0.28, 8.5.0 to 8.5.47, 7.0.0 and 7.0.97 is configured with the JMX Remote Lifecycle Listener, a local attacker without access to the Tomcat process or configuration files is able to manipulate the RMI registry to perform a man-in-the-middle attack to capture user names and passwords used to access the JMX interface. The attacker can then use these credentials to access the JMX interface and gain complete control over the Tomcat instance. | ||||
| CVE-2019-12295 | 4 Canonical, Debian, F5 and 1 more | 16 Ubuntu Linux, Debian Linux, Big-ip Access Policy Manager and 13 more | 2024-11-21 | 7.5 High |
| In Wireshark 3.0.0 to 3.0.1, 2.6.0 to 2.6.8, and 2.4.0 to 2.4.14, the dissection engine could crash. This was addressed in epan/packet.c by restricting the number of layers and consequently limiting recursion. | ||||
| CVE-2019-12221 | 5 Canonical, Debian, Fedoraproject and 2 more | 7 Ubuntu Linux, Debian Linux, Fedora and 4 more | 2024-11-21 | 6.5 Medium |
| An issue was discovered in libSDL2.a in Simple DirectMedia Layer (SDL) 2.0.9 when used in conjunction with libSDL2_image.a in SDL2_image 2.0.4. There is a SEGV in the SDL function SDL_free_REAL at stdlib/SDL_malloc.c. | ||||
