CVE-2020-27820 3 Fedoraproject, Linux, Oracle 5 Fedora, Linux Kernel, Communications Cloud Native Core Binding Support Function and 2 more 2024-11-21 4.7 MEDIUM 4.7 MEDIUM
A vulnerability was found in Linux kernel, where a use-after-frees in nouveau's postclose() handler could happen if removing device (that is not common to remove video card physically without power-off, but same happens if "unbind" the driver).
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-2020-27783 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-2020-27781 2 Fedoraproject, Redhat 5 Fedora, Ceph, Ceph Storage and 2 more 2024-11-21 3.6 LOW 7.1 HIGH
User credentials can be manipulated and stolen by Native CephFS consumers of OpenStack Manila, resulting in potential privilege escalation. An Open Stack Manila user can request access to a share to an arbitrary cephx user, including existing users. The access key is retrieved via the interface drivers. Then, all users of the requesting OpenStack project can view the access key. This enables the attacker to target any resource that the user has access to. This can be done to even "admin" users, compromising the ceph administrator. This flaw affects Ceph versions prior to 14.2.16, 15.x prior to 15.2.8, and 16.x prior to 16.2.0.
CVE-2020-27779 4 Fedoraproject, Gnu, Netapp and 1 more 8 Fedora, Grub2, Ontap Select Deploy Administration Utility and 5 more 2024-11-21 6.9 MEDIUM 7.5 HIGH
A flaw was found in grub2 in versions prior to 2.06. The cutmem command does not honor secure boot locking allowing an privileged attacker to remove address ranges from memory creating an opportunity to circumvent SecureBoot protections after proper triage about grub's memory layout. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2020-27769 3 Fedoraproject, Imagemagick, Redhat 3 Fedora, Imagemagick, Enterprise Linux Desktop 2024-11-21 4.3 MEDIUM 3.3 LOW
In ImageMagick versions before 7.0.9-0, there are outside the range of representable values of type 'float' at MagickCore/quantize.c.
CVE-2020-27749 4 Fedoraproject, Gnu, Netapp and 1 more 8 Fedora, Grub2, Ontap Select Deploy Administration Utility and 5 more 2024-11-21 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-2020-27675 3 Debian, Fedoraproject, Linux 3 Debian Linux, Fedora, Linux Kernel 2024-11-21 4.7 MEDIUM 4.7 MEDIUM
An issue was discovered in the Linux kernel through 5.9.1, as used with Xen through 4.14.x. drivers/xen/events/events_base.c allows event-channel removal during the event-handling loop (a race condition). This can cause a use-after-free or NULL pointer dereference, as demonstrated by a dom0 crash via events for an in-reconfiguration paravirtualized device, aka CID-073d0552ead5.
CVE-2020-27674 3 Debian, Fedoraproject, Xen 3 Debian Linux, Fedora, Xen 2024-11-21 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-2020-27672 4 Debian, Fedoraproject, Opensuse and 1 more 4 Debian Linux, Fedora, Leap and 1 more 2024-11-21 6.9 MEDIUM 7.0 HIGH
An issue was discovered in Xen through 4.14.x allowing x86 guest OS users to cause a host OS denial of service, achieve data corruption, or possibly gain privileges by exploiting a race condition that leads to a use-after-free involving 2MiB and 1GiB superpages.
CVE-2020-27671 4 Debian, Fedoraproject, Opensuse and 1 more 4 Debian Linux, Fedora, Leap and 1 more 2024-11-21 6.9 MEDIUM 7.8 HIGH
An issue was discovered in Xen through 4.14.x allowing x86 HVM and PVH guest OS users to cause a denial of service (data corruption), cause a data leak, or possibly gain privileges because coalescing of per-page IOMMU TLB flushes is mishandled.
CVE-2020-27670 4 Debian, Fedoraproject, Opensuse and 1 more 4 Debian Linux, Fedora, Leap and 1 more 2024-11-21 6.9 MEDIUM 7.8 HIGH
An issue was discovered in Xen through 4.14.x allowing x86 guest OS users to cause a denial of service (data corruption), cause a data leak, or possibly gain privileges because an AMD IOMMU page-table entry can be half-updated.
CVE-2020-27638 3 Debian, Fastd Project, Fedoraproject 3 Debian Linux, Fastd, Fedora 2024-11-21 5.0 MEDIUM 7.5 HIGH
receive.c in fastd before v21 allows denial of service (assertion failure) when receiving packets with an invalid type code.
CVE-2020-27619 3 Fedoraproject, Oracle, Python 3 Fedora, Communications Cloud Native Core Network Function Cloud Native Environment, Python 2024-11-21 7.5 HIGH 9.8 CRITICAL
In Python 3 through 3.9.0, the Lib/test/multibytecodec_support.py CJK codec tests call eval() on content retrieved via HTTP.
CVE-2020-27171 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2024-11-21 3.6 LOW 6.0 MEDIUM
An issue was discovered in the Linux kernel before 5.11.8. kernel/bpf/verifier.c has an off-by-one error (with a resultant integer underflow) affecting out-of-bounds speculation on pointer arithmetic, leading to side-channel attacks that defeat Spectre mitigations and obtain sensitive information from kernel memory, aka CID-10d2bb2e6b1d.
CVE-2020-27170 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2024-11-21 1.9 LOW 4.7 MEDIUM
An issue was discovered in the Linux kernel before 5.11.8. kernel/bpf/verifier.c performs undesirable out-of-bounds speculation on pointer arithmetic, leading to side-channel attacks that defeat Spectre mitigations and obtain sensitive information from kernel memory, aka CID-f232326f6966. This affects pointer types that do not define a ptr_limit.
CVE-2020-26935 4 Debian, Fedoraproject, Opensuse and 1 more 5 Debian Linux, Fedora, Backports Sle and 2 more 2024-11-21 7.5 HIGH 9.8 CRITICAL
An issue was discovered in SearchController in phpMyAdmin before 4.9.6 and 5.x before 5.0.3. A SQL injection vulnerability was discovered in how phpMyAdmin processes SQL statements in the search feature. An attacker could use this flaw to inject malicious SQL in to a query.
CVE-2020-26934 4 Debian, Fedoraproject, Opensuse and 1 more 5 Debian Linux, Fedora, Backports Sle and 2 more 2024-11-21 4.3 MEDIUM 6.1 MEDIUM
phpMyAdmin before 4.9.6 and 5.x before 5.0.3 allows XSS through the transformation feature via a crafted link.
CVE-2020-26892 2 Fedoraproject, Linuxfoundation 2 Fedora, Nats-server 2024-11-21 7.5 HIGH 9.8 CRITICAL
The JWT library in NATS nats-server before 2.1.9 has Incorrect Access Control because of how expired credentials are handled.
CVE-2020-26890 2 Fedoraproject, Matrix 2 Fedora, Synapse 2024-11-21 5.0 MEDIUM 7.5 HIGH
Matrix Synapse before 1.20.0 erroneously permits non-standard NaN, Infinity, and -Infinity JSON values in fields of m.room.member events, allowing remote attackers to execute a denial of service attack against the federation and common Matrix clients. If such a malformed event is accepted into the room's state, the impact is long-lasting and is not fixed by an upgrade to a newer version, requiring the event to be manually redacted instead. Since events are replicated to servers of other room members, the impact is not constrained to the server of the event sender.
