| CVE-2020-27821 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2023-11-07 | 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-2020-27749 | 4 Fedoraproject, Gnu, Netapp and 1 more | 8 Fedora, Grub2, Ontap Select Deploy Administration Utility and 5 more | 2023-11-07 | 7.2 HIGH | 6.7 MEDIUM |
| A flaw was found in grub2 in versions prior to 2.06. Variable names present are expanded in the supplied command line into their corresponding variable contents, using a 1kB stack buffer for temporary storage, without sufficient bounds checking. If the function is called with a command line that references a variable with a sufficiently large payload, it is possible to overflow the stack buffer, corrupt the stack frame and control execution which could also circumvent Secure Boot protections. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | |||||
| CVE-2020-27674 | 3 Debian, Fedoraproject, Xen | 3 Debian Linux, Fedora, Xen | 2023-11-07 | 4.6 MEDIUM | 5.3 MEDIUM |
| An issue was discovered in Xen through 4.14.x allowing x86 PV guest OS users to gain guest OS privileges by modifying kernel memory contents, because invalidation of TLB entries is mishandled during use of an INVLPG-like attack technique. | |||||

| CVE-2020-26519 | 3 Artifex, Debian, Fedoraproject | 3 Mupdf, Debian Linux, Fedora | 2023-11-07 | 4.3 MEDIUM | 5.5 MEDIUM |
| Artifex MuPDF before 1.18.0 has a heap based buffer over-write when parsing JBIG2 files allowing attackers to cause a denial of service. | |||||
| CVE-2020-25693 | 2 Cimg, Fedoraproject | 2 Cimg, Fedora | 2023-11-07 | 5.8 MEDIUM | 8.1 HIGH |
| A flaw was found in CImg in versions prior to 2.9.3. Integer overflows leading to heap buffer overflows in load_pnm() can be triggered by a specially crafted input file processed by CImg, which can lead to an impact to application availability or data integrity. | |||||
| CVE-2020-25682 | 3 Debian, Fedoraproject, Thekelleys | 3 Debian Linux, Fedora, Dnsmasq | 2023-11-07 | 8.3 HIGH | 8.1 HIGH |
| A flaw was found in dnsmasq before 2.83. A buffer overflow vulnerability was discovered in the way dnsmasq extract names from DNS packets before validating them with DNSSEC data. An attacker on the network, who can create valid DNS replies, could use this flaw to cause an overflow with arbitrary data in a heap-allocated memory, possibly executing code on the machine. The flaw is in the rfc1035.c:extract_name() function, which writes data to the memory pointed by name assuming MAXDNAME*2 bytes are available in the buffer. However, in some code execution paths, it is possible extract_name() gets passed an offset from the base buffer, thus reducing, in practice, the number of available bytes that can be written in the buffer. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | |||||
| CVE-2020-25647 | 4 Fedoraproject, Gnu, Netapp and 1 more | 8 Fedora, Grub2, Ontap Select Deploy Administration Utility and 5 more | 2023-11-07 | 7.2 HIGH | 7.6 HIGH |
| A flaw was found in grub2 in versions prior to 2.06. During USB device initialization, descriptors are read with very little bounds checking and assumes the USB device is providing sane values. If properly exploited, an attacker could trigger memory corruption leading to arbitrary code execution allowing a bypass of the Secure Boot mechanism. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. | |||||
| CVE-2020-25600 | 4 Debian, Fedoraproject, Opensuse and 1 more | 4 Debian Linux, Fedora, Leap and 1 more | 2023-11-07 | 4.9 MEDIUM | 5.5 MEDIUM |
| An issue was discovered in Xen through 4.14.x. Out of bounds event channels are available to 32-bit x86 domains. The so called 2-level event channel model imposes different limits on the number of usable event channels for 32-bit x86 domains vs 64-bit or Arm (either bitness) ones. 32-bit x86 domains can use only 1023 channels, due to limited space in their shared (between guest and Xen) information structure, whereas all other domains can use up to 4095 in this model. The recording of the respective limit during domain initialization, however, has occurred at a time where domains are still deemed to be 64-bit ones, prior to actually honoring respective domain properties. At the point domains get recognized as 32-bit ones, the limit didn't get updated accordingly. Due to this misbehavior in Xen, 32-bit domains (including Domain 0) servicing other domains may observe event channel allocations to succeed when they should really fail. Subsequent use of such event channels would then possibly lead to corruption of other parts of the shared info structure. An unprivileged guest may cause another domain, in particular Domain 0, to misbehave. This may lead to a Denial of Service (DoS) for the entire system. All Xen versions from 4.4 onwards are vulnerable. Xen versions 4.3 and earlier are not vulnerable. Only x86 32-bit domains servicing other domains are vulnerable. Arm systems, as well as x86 64-bit domains, are not vulnerable. | |||||
| CVE-2020-24659 | 4 Canonical, Fedoraproject, Gnu and 1 more | 4 Ubuntu Linux, Fedora, Gnutls and 1 more | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in GnuTLS before 3.6.15. A server can trigger a NULL pointer dereference in a TLS 1.3 client if a no_renegotiation alert is sent with unexpected timing, and then an invalid second handshake occurs. The crash happens in the application's error handling path, where the gnutls_deinit function is called after detecting a handshake failure. | |||||
| CVE-2020-24388 | 2 Fedoraproject, Yubico | 2 Fedora, Yubihsm-shell | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in the _send_secure_msg() function of yubihsm-shell through 2.0.2. The function does not validate the embedded length field of a message received from the device. This could lead to an oversized memcpy() call that will crash the running process. This could be used by an attacker to cause a denial of service. | |||||
| CVE-2020-24387 | 2 Fedoraproject, Yubico | 2 Fedora, Yubihsm-shell | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in the yh_create_session() function of yubihsm-shell through 2.0.2. The function does not explicitly check the returned session id from the device. An invalid session id would lead to out-of-bounds read and write operations in the session array. This could be used by an attacker to cause a denial of service attack. | |||||
| CVE-2020-24266 | 2 Broadcom, Fedoraproject | 2 Tcpreplay, Fedora | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in tcpreplay tcpprep v4.3.3. There is a heap buffer overflow vulnerability in get_l2len() that can make tcpprep crash and cause a denial of service. | |||||
| CVE-2020-24265 | 2 Broadcom, Fedoraproject | 2 Tcpreplay, Fedora | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
| An issue was discovered in tcpreplay tcpprep v4.3.3. There is a heap buffer overflow vulnerability in MemcmpInterceptorCommon() that can make tcpprep crash and cause a denial of service. | |||||

| CVE-2020-21047 | 1 Elfutils Project | 1 Elfutils | 2023-11-07 | N/A | 5.5 MEDIUM |
| The libcpu component which is used by libasm of elfutils version 0.177 (git 47780c9e), suffers from denial-of-service vulnerability caused by application crashes due to out-of-bounds write (CWE-787), off-by-one error (CWE-193) and reachable assertion (CWE-617); to exploit the vulnerability, the attackers need to craft certain ELF files which bypass the missing bound checks. | |||||
| CVE-2020-20740 | 3 Debian, Fedoraproject, Pdfresurrect Project | 3 Debian Linux, Fedora, Pdfresurrect | 2023-11-07 | 6.8 MEDIUM | 7.8 HIGH |
