CVE-2021-3444 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2024-11-21 7.8 High
The bpf verifier in the Linux kernel did not properly handle mod32 destination register truncation when the source register was known to be 0. A local attacker with the ability to load bpf programs could use this gain out-of-bounds reads in kernel memory leading to information disclosure (kernel memory), and possibly out-of-bounds writes that could potentially lead to code execution. This issue was addressed in the upstream kernel in commit 9b00f1b78809 ("bpf: Fix truncation handling for mod32 dst reg wrt zero") and in Linux stable kernels 5.11.2, 5.10.19, and 5.4.101.
CVE-2021-3416 4 Debian, Fedoraproject, Qemu and 1 more 5 Debian Linux, Fedora, Qemu and 2 more 2024-11-21 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-2021-3410 3 Debian, Fedoraproject, Libcaca Project 3 Debian Linux, Fedora, Libcaca 2024-11-21 7.8 High
A flaw was found in libcaca v0.99.beta19. A buffer overflow issue in caca_resize function in libcaca/caca/canvas.c may lead to local execution of arbitrary code in the user context.
CVE-2021-3409 4 Debian, Fedoraproject, Qemu and 1 more 4 Debian Linux, Fedora, Qemu and 1 more 2024-11-21 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-2021-3405 3 Debian, Fedoraproject, Matroska 3 Debian Linux, Fedora, Libebml 2024-11-21 6.5 Medium
A flaw was found in libebml before 1.4.2. A heap overflow bug exists in the implementation of EbmlString::ReadData and EbmlUnicodeString::ReadData in libebml.
CVE-2021-3392 3 Debian, Fedoraproject, Qemu 3 Debian Linux, Fedora, Qemu 2024-11-21 3.2 Low
A use-after-free flaw was found in the MegaRAID emulator of QEMU. This issue occurs while processing SCSI I/O requests in the case of an error mptsas_free_request() that does not dequeue the request object 'req' from a pending requests queue. This flaw allows a privileged guest user to crash the QEMU process on the host, resulting in a denial of service. Versions between 2.10.0 and 5.2.0 are potentially affected.
CVE-2021-3348 3 Debian, Linux, Redhat 3 Debian Linux, Linux Kernel, Enterprise Linux 2024-11-21 7.0 High
nbd_add_socket in drivers/block/nbd.c in the Linux kernel through 5.10.12 has an ndb_queue_rq use-after-free that could be triggered by local attackers (with access to the nbd device) via an I/O request at a certain point during device setup, aka CID-b98e762e3d71.
CVE-2021-3246 4 Debian, Fedoraproject, Libsndfile Project and 1 more 5 Debian Linux, Fedora, Libsndfile and 2 more 2024-11-21 8.8 High
A heap buffer overflow vulnerability in msadpcm_decode_block of libsndfile 1.0.30 allows attackers to execute arbitrary code via a crafted WAV file.
CVE-2021-3197 3 Debian, Fedoraproject, Saltstack 3 Debian Linux, Fedora, Salt 2024-11-21 9.8 Critical
An issue was discovered in SaltStack Salt before 3002.5. The salt-api's ssh client is vulnerable to a shell injection by including ProxyCommand in an argument, or via ssh_options provided in an API request.
CVE-2021-3181 4 Debian, Fedoraproject, Mutt and 1 more 4 Debian Linux, Fedora, Mutt and 1 more 2024-11-21 6.5 Medium
rfc822.c in Mutt through 2.0.4 allows remote attackers to cause a denial of service (mailbox unavailability) by sending email messages with sequences of semicolon characters in RFC822 address fields (aka terminators of empty groups). A small email message from the attacker can cause large memory consumption, and the victim may then be unable to see email messages from other persons.
CVE-2021-3178 3 Debian, Fedoraproject, Linux 3 Debian Linux, Fedora, Linux Kernel 2024-11-21 6.5 Medium
fs/nfsd/nfs3xdr.c in the Linux kernel through 5.10.8, when there is an NFS export of a subdirectory of a filesystem, allows remote attackers to traverse to other parts of the filesystem via READDIRPLUS. NOTE: some parties argue that such a subdirectory export is not intended to prevent this attack; see also the exports(5) no_subtree_check default behavior
CVE-2021-3177 6 Debian, Fedoraproject, Netapp and 3 more 12 Debian Linux, Fedora, Active Iq Unified Manager and 9 more 2024-11-21 9.8 Critical
Python 3.x through 3.9.1 has a buffer overflow in PyCArg_repr in _ctypes/callproc.c, which may lead to remote code execution in certain Python applications that accept floating-point numbers as untrusted input, as demonstrated by a 1e300 argument to c_double.from_param. This occurs because sprintf is used unsafely.
CVE-2021-3148 3 Debian, Fedoraproject, Saltstack 3 Debian Linux, Fedora, Salt 2024-11-21 9.8 Critical
An issue was discovered in SaltStack Salt before 3002.5. Sending crafted web requests to the Salt API can result in salt.utils.thin.gen_thin() command injection because of different handling of single versus double quotes. This is related to salt/utils/thin.py.
CVE-2021-3144 3 Debian, Fedoraproject, Saltstack 3 Debian Linux, Fedora, Salt 2024-11-21 9.1 Critical
In SaltStack Salt before 3002.5, eauth tokens can be used once after expiration. (They might be used to run command against the salt master or minions.)
CVE-2021-3114 5 Debian, Fedoraproject, Golang and 2 more 13 Debian Linux, Fedora, Go and 10 more 2024-11-21 6.5 Medium
In Go before 1.14.14 and 1.15.x before 1.15.7, crypto/elliptic/p224.go can generate incorrect outputs, related to an underflow of the lowest limb during the final complete reduction in the P-224 field.
