CVE-2021-3516 6 Debian, Fedoraproject, Netapp and 3 more 9 Debian Linux, Fedora, Clustered Data Ontap and 6 more 2024-11-21 6.8 MEDIUM 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-2021-3507 3 Debian, Qemu, Redhat 3 Debian Linux, Qemu, Enterprise Linux 2024-11-21 3.6 LOW 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 2.1 LOW 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 5.8 MEDIUM 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-2021-3501 4 Fedoraproject, Linux, Netapp and 1 more 27 Fedora, Linux Kernel, Cloud Backup and 24 more 2024-11-21 3.6 LOW 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 6.8 MEDIUM 7.8 HIGH
GStreamer before 1.18.4 might cause heap corruption when parsing certain malformed Matroska files.
CVE-2021-3497 3 Debian, Gstreamer Project, Redhat 3 Debian Linux, Gstreamer, Enterprise Linux 2024-11-21 6.8 MEDIUM 7.8 HIGH
GStreamer before 1.18.4 might access already-freed memory in error code paths when demuxing certain malformed Matroska files.
CVE-2021-3482 4 Debian, Exiv2, Fedoraproject and 1 more 4 Debian Linux, Exiv2, Fedora and 1 more 2024-11-21 6.4 MEDIUM 6.5 MEDIUM
A flaw was found in Exiv2 in versions before and including 0.27.4-RC1. Improper input validation of the rawData.size property in Jp2Image::readMetadata() in jp2image.cpp can lead to a heap-based buffer overflow via a crafted JPG image containing malicious EXIF data.
CVE-2021-3472 4 Debian, Fedoraproject, Redhat and 1 more 4 Debian Linux, Fedora, Enterprise Linux and 1 more 2024-11-21 7.2 HIGH 7.8 HIGH
A flaw was found in xorg-x11-server in versions before 1.20.11. An integer underflow can occur in xserver which can lead to a local privilege escalation. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2021-3466 3 Fedoraproject, Gnu, Redhat 3 Fedora, Libmicrohttpd, Enterprise Linux 2024-11-21 10.0 HIGH 9.8 CRITICAL
A flaw was found in libmicrohttpd. A missing bounds check in the post_process_urlencoded function leads to a buffer overflow, allowing a remote attacker to write arbitrary data in an application that uses libmicrohttpd. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. Only version 0.9.70 is vulnerable.
CVE-2021-3448 4 Fedoraproject, Oracle, Redhat and 1 more 4 Fedora, Communications Cloud Native Core Network Function Cloud Native Environment, Enterprise Linux and 1 more 2024-11-21 4.3 MEDIUM 4.0 MEDIUM
A flaw was found in dnsmasq in versions before 2.85. When configured to use a specific server for a given network interface, dnsmasq uses a fixed port while forwarding queries. An attacker on the network, able to find the outgoing port used by dnsmasq, only needs to guess the random transmission ID to forge a reply and get it accepted by dnsmasq. This flaw makes a DNS Cache Poisoning attack much easier. The highest threat from this vulnerability is to data integrity.
CVE-2021-3446 3 Fedoraproject, Libtpms Project, Redhat 3 Fedora, Libtpms, Enterprise Linux 2024-11-21 2.1 LOW 5.5 MEDIUM
A flaw was found in libtpms in versions before 0.8.2. The commonly used integration of libtpms with OpenSSL contained a vulnerability related to the returned IV (initialization vector) when certain symmetric ciphers were used. Instead of returning the last IV it returned the initial IV to the caller, thus weakening the subsequent encryption and decryption steps. The highest threat from this vulnerability is to data confidentiality.
CVE-2021-3445 3 Fedoraproject, Redhat, Rpm 3 Fedora, Enterprise Linux, Libdnf 2024-11-21 5.1 MEDIUM 7.5 HIGH
A flaw was found in libdnf's signature verification functionality in versions before 0.60.1. This flaw allows an attacker to achieve code execution if they can alter the header information of an RPM package and then trick a user or system into installing it. The highest risk of this vulnerability is to confidentiality, integrity, as well as system availability.
CVE-2021-3443 3 Fedoraproject, Jasper Project, Redhat 3 Fedora, Jasper, Enterprise Linux 2024-11-21 4.3 MEDIUM 5.5 MEDIUM
A NULL pointer dereference flaw was found in the way Jasper versions before 2.0.27 handled component references in the JP2 image format decoder. A specially crafted JP2 image file could cause an application using the Jasper library to crash when opened.
CVE-2021-3426 6 Debian, Fedoraproject, Netapp and 3 more 10 Debian Linux, Fedora, Cloud Backup and 7 more 2024-11-21 2.7 LOW 5.7 MEDIUM
There's a flaw in Python 3's pydoc. A local or adjacent attacker who discovers or is able to convince another local or adjacent user to start a pydoc server could access the server and use it to disclose sensitive information belonging to the other user that they would not normally be able to access. The highest risk of this flaw is to data confidentiality. This flaw affects Python versions before 3.8.9, Python versions before 3.9.3 and Python versions before 3.10.0a7.
CVE-2021-3421 3 Fedoraproject, Redhat, Rpm 3 Fedora, Enterprise Linux, Rpm 2024-11-21 4.3 MEDIUM 5.5 MEDIUM
A flaw was found in the RPM package in the read functionality. This flaw allows an attacker who can convince a victim to install a seemingly verifiable package or compromise an RPM repository, to cause RPM database corruption. The highest threat from this vulnerability is to data integrity. This flaw affects RPM versions before 4.17.0-alpha.
CVE-2021-3416 4 Debian, Fedoraproject, Qemu and 1 more 4 Debian Linux, Fedora, Qemu and 1 more 2024-11-21 2.1 LOW 6.0 MEDIUM
A potential stack overflow via infinite loop issue was found in various NIC emulators of QEMU in versions up to and including 5.2.0. The issue occurs in loopback mode of a NIC wherein reentrant DMA checks get bypassed. A guest user/process may use this flaw to consume CPU cycles or crash the QEMU process on the host resulting in DoS scenario.
CVE-2021-3411 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2024-11-21 4.6 MEDIUM 6.7 MEDIUM
A flaw was found in the Linux kernel in versions prior to 5.10. A violation of memory access was found while detecting a padding of int3 in the linking state. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2021-3409 4 Debian, Fedoraproject, Qemu and 1 more 4 Debian Linux, Fedora, Qemu and 1 more 2024-11-21 4.6 MEDIUM 5.7 MEDIUM
The patch for CVE-2020-17380/CVE-2020-25085 was found to be ineffective, thus making QEMU vulnerable to the out-of-bounds read/write access issues previously found in the SDHCI controller emulation code. This flaw allows a malicious privileged guest to crash the QEMU process on the host, resulting in a denial of service or potential code execution. QEMU up to (including) 5.2.0 is affected by this.
CVE-2021-3404 3 Fedoraproject, Redhat, Ytnef Project 3 Fedora, Enterprise Linux, Ytnef 2024-11-21 6.8 MEDIUM 7.8 HIGH
In ytnef 1.9.3, the SwapWord function in lib/ytnef.c allows remote attackers to cause a denial-of-service (and potentially code execution) due to a heap buffer overflow which can be triggered via a crafted file.
