Uncontrolled Resource Consumption in promhttp

client_golang is the instrumentation library for Go applications in Prometheus, and the promhttp package in client_golang provides tooling around HTTP servers and clients. In client_golang prior to version 1.11.1, HTTP server is susceptible to a Denial of Service through unbounded cardinality, and potential memory exhaustion, when handling requests with non-standard HTTP methods. In order to be affected, an instrumented software must use any of `promhttp.InstrumentHandler*` middleware except `RequestsInFlight`; not filter any specific methods (e.g GET) before middleware; pass metric with `method` label name to our middleware; and not have any firewall/LB/proxy that filters away requests with unknown `method`. client_golang version 1.11.1 contains a patch for this issue. Several workarounds are available, including removing the `method` label name from counter/gauge used in the InstrumentHandler; turning off affected promhttp handlers; adding custom middleware before promhttp handler that will sanitize the request method given by Go http.Request; and using a reverse proxy or web application firewall, configured to only allow a limited set of methods.

The rxvt-unicode package is vulnerable to a remote code execution, in the Perl background extension, when an attacker can control the data written to the user's terminal and certain options are set.

QEMU: QXL: qxl_phys2virt unsafe address translation can lead to out-of-bounds read

An out-of-bounds read flaw was found in the QXL display device emulation in QEMU. The qxl_phys2virt() function does not check the size of the structure pointed to by the guest physical address, potentially reading past the end of the bar space into adjacent pages. A malicious guest user could use this flaw to crash the QEMU process on the host causing a denial of service condition.

haproxy: segfault DoS

An uncontrolled resource consumption vulnerability was discovered in HAProxy which could crash the service. This issue could allow an authenticated remote attacker to run a specially crafted malicious server in an OpenShift cluster. The biggest impact is to availability.

Mock: privilege escalation for users that can access mock configuration

The Mock software contains a vulnerability wherein an attacker could potentially exploit privilege escalation, enabling the execution of arbitrary code with root user privileges. This weakness stems from the absence of proper sandboxing during the expansion and execution of Jinja2 templates, which may be included in certain configuration parameters. While the Mock documentation advises treating users added to the mock group as privileged, certain build systems invoking mock on behalf of users might inadvertently permit less privileged users to define configuration tags. These tags could then be passed as parameters to mock during execution, potentially leading to the utilization of Jinja2 templates for remote privilege escalation and the execution of arbitrary code as the root user on the build server.

Tcpreplay: tcprewrite: double free in tcpedit_dlt_cleanup() in plugins/dlt_plugins.c

Within tcpreplay's tcprewrite, a double free vulnerability has been identified in the tcpedit_dlt_cleanup() function within plugins/dlt_plugins.c. This vulnerability can be exploited by supplying a specifically crafted file to the tcprewrite binary. This flaw enables a local attacker to initiate a Denial of Service (DoS) attack.

W3m: out-of-bounds write in function checktype() in etc.c (incomplete fix for cve-2022-38223)

An out-of-bounds write issue has been discovered in the backspace handling of the checkType() function in etc.c within the W3M application. This vulnerability is triggered by supplying a specially crafted HTML file to the w3m binary. Exploitation of this flaw could lead to application crashes, resulting in a denial of service condition.

W3m: out of bounds read in growbuf_to_str() at w3m/indep.c

An out-of-bounds read flaw was found in w3m, in the growbuf_to_Str function in indep.c. This issue may allow an attacker to cause a denial of service through a crafted HTML file.

ImageMagick: heap-based buffer overflow in ImportMultiSpectralQuantum() in MagickCore/quantum-import.c

A heap-based buffer overflow issue was discovered in ImageMagick's ImportMultiSpectralQuantum() function in MagickCore/quantum-import.c. An attacker could pass specially crafted file to convert, triggering an out-of-bounds read error, allowing an application to crash, resulting in a denial of service.

ImageMagick: RCE (shell command injection) vulnerability in OpenBlob with --enable-pipes configured

A vulnerability was found in ImageMagick. This security flaw cause a remote code execution vulnerability in OpenBlob with --enable-pipes configured.

ImageMagick: heap use-after-free issue in ReplaceXmpValue() function in MagickCore/profile.c.

A heap use after free issue was discovered in ImageMagick's ReplaceXmpValue() function in MagickCore/profile.c. An attacker could trick user to open a specially crafted file to convert, triggering an heap-use-after-free write error, allowing an application to crash, resulting in a denial of service.

ImageMagick: stack overflow in coders/tiff.c while parsing malicious tiff file

A stack-based buffer overflow issue was found in ImageMagick's coders/tiff.c. This flaw allows an attacker to trick the user into opening a specially crafted malicious tiff file, causing an application to crash, resulting in a denial of service.

ImageMagick: Undefined behaviors of casting double to size_t in svg, mvg and other coders

A vulnerability was found in ImageMagick. This security flaw ouccers as an undefined behaviors of casting double to size_t in svg, mvg and other coders (recurring bugs of CVE-2022-32546).

Moodle: forum summary report shows students from other groups when in separate groups mode

Separate Groups mode restrictions were not honoured in the forum summary report, which would display users from other groups.

Moodle: rce due to lfi risk in some misconfigured shared hosting environments

In a shared hosting environment that has been misconfigured to allow access to other users' content, a Moodle user who also has direct access to the web server outside of the Moodle webroot could utilise a local file include to achieve remote code execution.

Moodle: insufficient capability checks when updating the parent of a course category

Insufficient web service capability checks made it possible to move categories a user had permission to manage, to a parent category they did not have the capability to manage.

Moodle: cache poisoning risk with endpoint revision numbers

Stronger revision number limitations were required on file serving endpoints to improve cache poisoning protection.

Moodle: auto-populated h5p author name causes a potential information leak

H5P metadata automatically populated the author with the user's username, which could be sensitive information.

Moodle: duplicating a bigbluebutton activity assigns the same meeting id

When duplicating a BigBlueButton activity, the original meeting ID was also duplicated instead of using a new ID for the new activity. This could provide unintended access to the original meeting.

Moodle: students can view other users in "only see own membership" groups

Students in "Only see own membership" groups could see other students in the group, which should be hidden.
