CVE-2021-20320 3 Fedoraproject, Linux, Redhat 3 Fedora, Linux Kernel, Enterprise Linux 2023-11-07 2.1 LOW 5.5 MEDIUM
A flaw was found in s390 eBPF JIT in bpf_jit_insn in arch/s390/net/bpf_jit_comp.c in the Linux kernel. In this flaw, a local attacker with special user privilege can circumvent the verifier and may lead to a confidentiality problem.
CVE-2021-20305 5 Debian, Fedoraproject, Netapp and 2 more 6 Debian Linux, Fedora, Active Iq Unified Manager and 3 more 2023-11-07 6.8 MEDIUM 8.1 HIGH
A flaw was found in Nettle in versions before 3.7.2, where several Nettle signature verification functions (GOST DSA, EDDSA & ECDSA) result in the Elliptic Curve Cryptography point (ECC) multiply function being called with out-of-range scalers, possibly resulting in incorrect results. This flaw allows an attacker to force an invalid signature, causing an assertion failure or possible validation. The highest threat to this vulnerability is to confidentiality, integrity, as well as system availability.
CVE-2021-20291 3 Fedoraproject, Redhat, Storage Project 4 Fedora, Enterprise Linux, Openshift Container Platform and 1 more 2023-11-07 7.1 HIGH 6.5 MEDIUM
A deadlock vulnerability was found in 'github.com/containers/storage' in versions before 1.28.1. When a container image is processed, each layer is unpacked using `tar`. If one of those layers is not a valid `tar` archive this causes an error leading to an unexpected situation where the code indefinitely waits for the tar unpacked stream, which never finishes. An attacker could use this vulnerability to craft a malicious image, which when downloaded and stored by an application using containers/storage, would then cause a deadlock leading to a Denial of Service (DoS).
CVE-2021-20254 4 Debian, Fedoraproject, Redhat and 1 more 4 Debian Linux, Fedora, Enterprise Linux and 1 more 2023-11-07 4.9 MEDIUM 6.8 MEDIUM
A flaw was found in samba. The Samba smbd file server must map Windows group identities (SIDs) into unix group ids (gids). The code that performs this had a flaw that could allow it to read data beyond the end of the array in the case where a negative cache entry had been added to the mapping cache. This could cause the calling code to return those values into the process token that stores the group membership for a user. The highest threat from this vulnerability is to data confidentiality and integrity.
CVE-2021-20239 3 Fedoraproject, Linux, Redhat 3 Fedora, Linux Kernel, Enterprise Linux 2023-11-07 2.1 LOW 3.3 LOW
A flaw was found in the Linux kernel in versions before 5.4.92 in the BPF protocol. This flaw allows an attacker with a local account to leak information about kernel internal addresses. The highest threat from this vulnerability is to confidentiality.
CVE-2021-20236 3 Fedoraproject, Redhat, Zeromq 4 Fedora, Ceph Storage, Enterprise Linux and 1 more 2023-11-07 7.5 HIGH 9.8 CRITICAL
A flaw was found in the ZeroMQ server in versions before 4.3.3. This flaw allows a malicious client to cause a stack buffer overflow on the server by sending crafted topic subscription requests and then unsubscribing. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
CVE-2021-20233 4 Fedoraproject, Gnu, Netapp and 1 more 8 Fedora, Grub2, Ontap Select Deploy Administration Utility and 5 more 2023-11-07 7.2 HIGH 8.2 HIGH
A flaw was found in grub2 in versions prior to 2.06. Setparam_prefix() in the menu rendering code performs a length calculation on the assumption that expressing a quoted single quote will require 3 characters, while it actually requires 4 characters which allows an attacker to corrupt memory by one byte for each quote in the input. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2021-20232 3 Fedoraproject, Gnu, Redhat 3 Fedora, Gnutls, Enterprise Linux 2023-11-07 7.5 HIGH 9.8 CRITICAL
A flaw was found in gnutls. A use after free issue in client_send_params in lib/ext/pre_shared_key.c may lead to memory corruption and other potential consequences.
CVE-2021-20231 4 Fedoraproject, Gnu, Netapp and 1 more 5 Fedora, Gnutls, Active Iq Unified Manager and 2 more 2023-11-07 7.5 HIGH 9.8 CRITICAL
A flaw was found in gnutls. A use after free issue in client sending key_share extension may lead to memory corruption and other consequences.
CVE-2021-20225 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. The option parser allows an attacker to write past the end of a heap-allocated buffer by calling certain commands with a large number of specific short forms of options. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2021-20221 3 Debian, Qemu, Redhat 3 Debian Linux, Qemu, Enterprise Linux 2023-11-07 2.1 LOW 6.0 MEDIUM
An out-of-bounds heap buffer access issue was found in the ARM Generic Interrupt Controller emulator of QEMU up to and including qemu 4.2.0on aarch64 platform. The issue occurs because while writing an interrupt ID to the controller memory area, it is not masked to be 4 bits wide. It may lead to the said issue while updating controller state fields and their subsequent processing. A privileged guest user may use this flaw to crash the QEMU process on the host resulting in DoS scenario.
CVE-2021-20208 3 Fedoraproject, Redhat, Samba 3 Fedora, Enterprise Linux, Cifs-utils 2023-11-07 4.9 MEDIUM 6.1 MEDIUM
A flaw was found in cifs-utils in versions before 6.13. A user when mounting a krb5 CIFS file system from within a container can use Kerberos credentials of the host. The highest threat from this vulnerability is to data confidentiality and integrity.
CVE-2021-20179 3 Dogtagpki, Fedoraproject, Redhat 4 Dogtagpki, Fedora, Certificate System and 1 more 2023-11-07 5.5 MEDIUM 8.1 HIGH
A flaw was found in pki-core. An attacker who has successfully compromised a key could use this flaw to renew the corresponding certificate over and over again, as long as it is not explicitly revoked. The highest threat from this vulnerability is to data confidentiality and integrity.
CVE-2020-9490 7 Apache, Canonical, Debian and 4 more 25 Http Server, Ubuntu Linux, Debian Linux and 22 more 2023-11-07 5.0 MEDIUM 7.5 HIGH
Apache HTTP Server versions 2.4.20 to 2.4.43. A specially crafted value for the 'Cache-Digest' header in a HTTP/2 request would result in a crash when the server actually tries to HTTP/2 PUSH a resource afterwards. Configuring the HTTP/2 feature via "H2Push off" will mitigate this vulnerability for unpatched servers.
CVE-2020-8945 3 Fedoraproject, Gpgme Project, Redhat 10 Fedora, Gpgme, Enterprise Linux and 7 more 2023-11-07 5.1 MEDIUM 7.5 HIGH
The proglottis Go wrapper before 0.1.1 for the GPGME library has a use-after-free, as demonstrated by use for container image pulls by Docker or CRI-O. This leads to a crash or potential code execution during GPG signature verification.
CVE-2020-6851 5 Debian, Fedoraproject, Oracle and 2 more 12 Debian Linux, Fedora, Georaster and 9 more 2023-11-07 5.0 MEDIUM 7.5 HIGH
OpenJPEG through 2.3.1 has a heap-based buffer overflow in opj_t1_clbl_decode_processor in openjp2/t1.c because of lack of opj_j2k_update_image_dimensions validation.
CVE-2020-36332 4 Debian, Netapp, Redhat and 1 more 4 Debian Linux, Ontap Select Deploy Administration Utility, Enterprise Linux and 1 more 2023-11-07 5.0 MEDIUM 7.5 HIGH
A flaw was found in libwebp in versions before 1.0.1. When reading a file libwebp allocates an excessive amount of memory. The highest threat from this vulnerability is to the service availability.
CVE-2020-35524 5 Debian, Fedoraproject, Libtiff and 2 more 5 Debian Linux, Fedora, Libtiff and 2 more 2023-11-07 6.8 MEDIUM 7.8 HIGH
A heap-based buffer overflow flaw was found in libtiff in the handling of TIFF images in libtiff's TIFF2PDF tool. A specially crafted TIFF file can lead to arbitrary code execution. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
CVE-2020-35523 4 Debian, Libtiff, Netapp and 1 more 4 Debian Linux, Libtiff, Ontap Select Deploy Administration Utility and 1 more 2023-11-07 6.8 MEDIUM 7.8 HIGH
An integer overflow flaw was found in libtiff that exists in the tif_getimage.c file. This flaw allows an attacker to inject and execute arbitrary code when a user opens a crafted TIFF file. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
CVE-2020-35522 4 Fedoraproject, Libtiff, Netapp and 1 more 4 Fedora, Libtiff, Ontap Select Deploy Administration Utility and 1 more 2023-11-07 4.3 MEDIUM 5.5 MEDIUM
