A vulnerability was found in ImageMagick. This security flaw causes a shell command injection vulnerability via video:vsync or video:pixel-format options in VIDEO encoding/decoding.
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.
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.
A vulnerability was discovered in ImageMagick where a specially created SVG file loads itself and causes a segmentation fault. This flaw allows a remote attacker to pass a specially crafted SVG file that leads to a segmentation fault, generating many trash files in "/tmp," resulting in a denial of service. When ImageMagick crashes, it generates a lot of trash files. These trash files can be large if the SVG file contains many render actions. In a denial of service attack, if a remote attacker uploads an SVG file of size t, ImageMagick generates files of size 103*t. If an attacker uploads a 100M SVG, the server will generate about 10G.
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.
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.
The H5P activity attempts report did not filter by groups, which in separate groups mode could reveal information to non-editing teachers about attempts/users in groups they should not have access to.
A heap buffer overflow issue was found in ImageMagick. When an application processes a malformed TIFF file, it could lead to undefined behavior or a crash causing a denial of service.
