There's a flaw in openjpeg's t2 encoder in versions prior to 2.4.0. An attacker who is able to provide crafted input to be processed by openjpeg could cause a null pointer dereference. The highest impact of this flaw is to application availability.
CVE-2020-27841 4 Debian, Fedoraproject, Oracle and 1 more 4 Debian Linux, Fedora, Outside In Technology and 1 more 2024-11-21 4.3 MEDIUM 5.5 MEDIUM
There's a flaw in openjpeg in versions prior to 2.4.0 in src/lib/openjp2/pi.c. When an attacker is able to provide crafted input to be processed by the openjpeg encoder, this could cause an out-of-bounds read. The greatest impact from this flaw is to application availability.
CVE-2020-27840 3 Debian, Fedoraproject, Samba 3 Debian Linux, Fedora, Samba 2024-11-21 5.0 MEDIUM 7.5 HIGH
A flaw was found in samba. Spaces used in a string around a domain name (DN), while supposed to be ignored, can cause invalid DN strings with spaces to instead write a zero-byte into out-of-bounds memory, resulting in a crash. The highest threat from this vulnerability is to system availability.
CVE-2020-27830 2 Debian, Linux 2 Debian Linux, Linux Kernel 2024-11-21 2.1 LOW 5.5 MEDIUM
A vulnerability was found in Linux Kernel where in the spk_ttyio_receive_buf2() function, it would dereference spk_ttyio_synth without checking whether it is NULL or not, and may lead to a NULL-ptr deref crash.
CVE-2020-27825 4 Debian, Linux, Netapp and 1 more 9 Debian Linux, Linux Kernel, Cloud Backup and 6 more 2024-11-21 5.4 MEDIUM 5.7 MEDIUM
A use-after-free flaw was found in kernel/trace/ring_buffer.c in Linux kernel (before 5.10-rc1). There was a race problem in trace_open and resize of cpu buffer running parallely on different cpus, may cause a denial of service problem (DOS). This flaw could even allow a local attacker with special user privilege to a kernel information leak threat.
CVE-2020-27824 4 Debian, Fedoraproject, Redhat and 1 more 4 Debian Linux, Fedora, Enterprise Linux and 1 more 2024-11-21 4.3 MEDIUM 5.5 MEDIUM
A flaw was found in OpenJPEG’s encoder in the opj_dwt_calc_explicit_stepsizes() function. This flaw allows an attacker who can supply crafted input to decomposition levels to cause a buffer overflow. The highest threat from this vulnerability is to system availability.
CVE-2020-27823 3 Debian, Fedoraproject, Uclouvain 3 Debian Linux, Fedora, Openjpeg 2024-11-21 6.8 MEDIUM 7.8 HIGH
A flaw was found in OpenJPEG’s encoder. This flaw allows an attacker to pass specially crafted x,y offset input to OpenJPEG to use during encoding. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
CVE-2020-27821 2 Debian, Qemu 2 Debian Linux, Qemu 2024-11-21 2.1 LOW 6.0 MEDIUM
A flaw was found in the memory management API of QEMU during the initialization of a memory region cache. This issue could lead to an out-of-bounds write access to the MSI-X table while performing MMIO operations. A guest user may abuse this flaw to crash the QEMU process on the host, resulting in a denial of service. This flaw affects QEMU versions prior to 5.2.0.
CVE-2020-27818 3 Debian, Fedoraproject, Libpng 4 Debian Linux, Extra Packages For Enterprise Linux, Fedora and 1 more 2024-11-21 4.3 MEDIUM 3.3 LOW
A flaw was found in the check_chunk_name() function of pngcheck-2.4.0. An attacker able to pass a malicious file to be processed by pngcheck could cause a temporary denial of service, posing a low risk to application availability.
CVE-2020-27815 3 Debian, Linux, Netapp 22 Debian Linux, Linux Kernel, Aff A250 and 19 more 2024-11-21 6.1 MEDIUM 7.8 HIGH
A flaw was found in the JFS filesystem code in the Linux Kernel which allows a local attacker with the ability to set extended attributes to panic the system, causing memory corruption or escalating privileges. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
CVE-2020-27814 2 Debian, Uclouvain 2 Debian Linux, Openjpeg 2024-11-21 6.8 MEDIUM 7.8 HIGH
A heap-buffer overflow was found in the way openjpeg2 handled certain PNG format files. An attacker could use this flaw to cause an application crash or in some cases execute arbitrary code with the permission of the user running such an application.
CVE-2020-27813 2 Debian, Gorillatoolkit 2 Debian Linux, Websocket 2024-11-21 5.0 MEDIUM 7.5 HIGH
An integer overflow vulnerability exists with the length of websocket frames received via a websocket connection. An attacker would use this flaw to cause a denial of service attack on an HTTP Server allowing websocket connections.
CVE-2020-27783 6 Debian, Fedoraproject, Lxml and 3 more 8 Debian Linux, Fedora, Lxml and 5 more 2024-11-21 4.3 MEDIUM 6.1 MEDIUM
A XSS vulnerability was discovered in python-lxml's clean module. The module's parser didn't properly imitate browsers, which caused different behaviors between the sanitizer and the user's page. A remote attacker could exploit this flaw to run arbitrary HTML/JS code.
CVE-2020-27778 3 Debian, Freedesktop, Redhat 3 Debian Linux, Poppler, Enterprise Linux 2024-11-21 5.0 MEDIUM 7.5 HIGH
A flaw was found in Poppler in the way certain PDF files were converted into HTML. A remote attacker could exploit this flaw by providing a malicious PDF file that, when processed by the 'pdftohtml' program, would crash the application causing a denial of service.
CVE-2020-27775 3 Debian, Imagemagick, Redhat 3 Debian Linux, Imagemagick, Enterprise Linux 2024-11-21 4.3 MEDIUM 3.3 LOW
A flaw was found in ImageMagick in MagickCore/quantum.h. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of values outside the range of type unsigned char. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. This flaw affects ImageMagick versions prior to 7.0.9-0.
CVE-2020-27774 3 Debian, Imagemagick, Redhat 3 Debian Linux, Imagemagick, Enterprise Linux 2024-11-21 4.3 MEDIUM 3.3 LOW
A flaw was found in ImageMagick in MagickCore/statistic.c. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of a too large shift for 64-bit type `ssize_t`. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. This flaw affects ImageMagick versions prior to 7.0.9-0.
CVE-2020-27773 3 Debian, Imagemagick, Redhat 3 Debian Linux, Imagemagick, Enterprise Linux 2024-11-21 4.3 MEDIUM 3.3 LOW
A flaw was found in ImageMagick in MagickCore/gem-private.h. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of values outside the range of type `unsigned char` or division by zero. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. This flaw affects ImageMagick versions prior to 7.0.9-0.
CVE-2020-27772 3 Debian, Imagemagick, Redhat 3 Debian Linux, Imagemagick, Enterprise Linux 2024-11-21 4.3 MEDIUM 3.3 LOW
A flaw was found in ImageMagick in coders/bmp.c. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of values outside the range of type `unsigned int`. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. This flaw affects ImageMagick versions prior to 7.0.9-0.
CVE-2020-27771 3 Debian, Imagemagick, Redhat 3 Debian Linux, Imagemagick, Enterprise Linux 2024-11-21 4.3 MEDIUM 3.3 LOW
In RestoreMSCWarning() of /coders/pdf.c there are several areas where calls to GetPixelIndex() could result in values outside the range of representable for the unsigned char type. The patch casts the return value of GetPixelIndex() to ssize_t type to avoid this bug. This undefined behavior could be triggered when ImageMagick processes a crafted pdf file. Red Hat Product Security marked this as Low severity because although it could potentially lead to an impact to application availability, no specific impact was demonstrated in this case. This flaw affects ImageMagick versions prior to 7.0.9-0.
CVE-2020-27770 2 Debian, Imagemagick 2 Debian Linux, Imagemagick 2024-11-21 4.3 MEDIUM 5.5 MEDIUM
Due to a missing check for 0 value of `replace_extent`, it is possible for offset `p` to overflow in SubstituteString(), causing potential impact to application availability. This could be triggered by a crafted input file that is processed by ImageMagick. This flaw affects ImageMagick versions prior to 7.0.8-68.
