CVE-2021-3537 6 Debian, Fedoraproject, Netapp and 3 more 21 Debian Linux, Fedora, Active Iq Unified Manager and 18 more 2024-11-21 5.9 Medium
A vulnerability found in libxml2 in versions before 2.9.11 shows that it did not propagate errors while parsing XML mixed content, causing a NULL dereference. If an untrusted XML document was parsed in recovery mode and post-validated, the flaw could be used to crash the application. The highest threat from this vulnerability is to system availability.
CVE-2021-3527 3 Debian, Qemu, Redhat 3 Debian Linux, Qemu, Enterprise Linux 2024-11-21 5.5 Medium
A flaw was found in the USB redirector device (usb-redir) of QEMU. Small USB packets are combined into a single, large transfer request, to reduce the overhead and improve performance. The combined size of the bulk transfer is used to dynamically allocate a variable length array (VLA) on the stack without proper validation. Since the total size is not bounded, a malicious guest could use this flaw to influence the array length and cause the QEMU process to perform an excessive allocation on the stack, resulting in a denial of service.
CVE-2021-3521 2 Redhat, Rpm 3 Enterprise Linux, Rhel Eus, Rpm 2024-11-21 4.7 Medium
There is a flaw in RPM's signature functionality. OpenPGP subkeys are associated with a primary key via a "binding signature." RPM does not check the binding signature of subkeys prior to importing them. If an attacker is able to add or socially engineer another party to add a malicious subkey to a legitimate public key, RPM could wrongly trust a malicious signature. The greatest impact of this flaw is to data integrity. To exploit this flaw, an attacker must either compromise an RPM repository or convince an administrator to install an untrusted RPM or public key. It is strongly recommended to only use RPMs and public keys from trusted sources.
CVE-2021-3520 5 Lz4 Project, Netapp, Oracle and 2 more 12 Lz4, Active Iq Unified Manager, Cloud Backup and 9 more 2024-11-21 9.8 Critical
There's a flaw in lz4. An attacker who submits a crafted file to an application linked with lz4 may be able to trigger an integer overflow, leading to calling of memmove() on a negative size argument, causing an out-of-bounds write and/or a crash. The greatest impact of this flaw is to availability, with some potential impact to confidentiality and integrity as well.
CVE-2021-3518 6 Debian, Fedoraproject, Netapp and 3 more 20 Debian Linux, Fedora, Active Iq Unified Manager and 17 more 2024-11-21 8.8 High
There's a flaw in libxml2 in versions before 2.9.11. An attacker who is able to submit a crafted file to be processed by an application linked with libxml2 could trigger a use-after-free. The greatest impact from this flaw is to confidentiality, integrity, and availability.
CVE-2021-3516 6 Debian, Fedoraproject, Netapp and 3 more 10 Debian Linux, Fedora, Clustered Data Ontap and 7 more 2024-11-21 7.8 High
There's a flaw in libxml2's xmllint in versions before 2.9.11. An attacker who is able to submit a crafted file to be processed by xmllint could trigger a use-after-free. The greatest impact of this flaw is to confidentiality, integrity, and availability.
CVE-2021-3514 1 Redhat 4 389 Directory Server, Directory Server, Enterprise Linux and 1 more 2024-11-21 6.5 Medium
When using a sync_repl client in 389-ds-base, an authenticated attacker can cause a NULL pointer dereference using a specially crafted query, causing a crash.
CVE-2021-3507 3 Debian, Qemu, Redhat 3 Debian Linux, Qemu, Enterprise Linux 2024-11-21 6.1 Medium
A heap buffer overflow was found in the floppy disk emulator of QEMU up to 6.0.0 (including). It could occur in fdctrl_transfer_handler() in hw/block/fdc.c while processing DMA read data transfers from the floppy drive to the guest system. A privileged guest user could use this flaw to crash the QEMU process on the host resulting in DoS scenario, or potential information leakage from the host memory.
CVE-2021-3505 3 Fedoraproject, Libtpms Project, Redhat 3 Fedora, Libtpms, Enterprise Linux 2024-11-21 5.5 Medium
A flaw was found in libtpms in versions before 0.8.0. The TPM 2 implementation returns 2048 bit keys with ~1984 bit strength due to a bug in the TCG specification. The bug is in the key creation algorithm in RsaAdjustPrimeCandidate(), which is called before the prime number check. The highest threat from this vulnerability is to data confidentiality.
CVE-2021-3504 3 Debian, Fedoraproject, Redhat 4 Debian Linux, Fedora, Enterprise Linux and 1 more 2024-11-21 5.4 Medium
A flaw was found in the hivex library in versions before 1.3.20. It is caused due to a lack of bounds check within the hivex_open function. An attacker could input a specially crafted Windows Registry (hive) file which would cause hivex to read memory beyond its normal bounds or cause the program to crash. The highest threat from this vulnerability is to system availability.
CVE-2021-3502 2 Avahi, Redhat 2 Avahi, Enterprise Linux 2024-11-21 5.5 Medium
A flaw was found in avahi 0.8-5. A reachable assertion is present in avahi_s_host_name_resolver_start function allowing a local attacker to crash the avahi service by requesting hostname resolutions through the avahi socket or dbus methods for invalid hostnames. The highest threat from this vulnerability is to the service availability.
CVE-2021-3501 4 Fedoraproject, Linux, Netapp and 1 more 28 Fedora, Linux Kernel, Cloud Backup and 25 more 2024-11-21 7.1 High
A flaw was found in the Linux kernel in versions before 5.12. The value of internal.ndata, in the KVM API, is mapped to an array index, which can be updated by a user process at anytime which could lead to an out-of-bounds write. The highest threat from this vulnerability is to data integrity and system availability.
CVE-2021-3498 3 Debian, Gstreamer Project, Redhat 3 Debian Linux, Gstreamer, Enterprise Linux 2024-11-21 7.8 High
GStreamer before 1.18.4 might cause heap corruption when parsing certain malformed Matroska files.

CVE-2021-3489 3 Canonical, Linux, Redhat 3 Ubuntu Linux, Linux Kernel, Enterprise Linux 2024-11-21 7.8 High
The eBPF RINGBUF bpf_ringbuf_reserve() function in the Linux kernel did not check that the allocated size was smaller than the ringbuf size, allowing an attacker to perform out-of-bounds writes within the kernel and therefore, arbitrary code execution. This issue was fixed via commit 4b81ccebaeee ("bpf, ringbuf: Deny reserve of buffers larger than ringbuf") (v5.13-rc4) and backported to the stable kernels in v5.12.4, v5.11.21, and v5.10.37. It was introduced via 457f44363a88 ("bpf: Implement BPF ring buffer and verifier support for it") (v5.8-rc1).
