| CVE-2021-3653 | 3 Debian, Linux, Redhat | 8 Debian Linux, Linux Kernel, Enterprise Linux and 5 more | 2024-11-21 | 8.8 High |
| A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when processing the VMCB (virtual machine control block) provided by the L1 guest to spawn/handle a nested guest (L2). Due to improper validation of the "int_ctl" field, this issue could allow a malicious L1 to enable AVIC support (Advanced Virtual Interrupt Controller) for the L2 guest. As a result, the L2 guest would be allowed to read/write physical pages of the host, resulting in a crash of the entire system, leak of sensitive data or potential guest-to-host escape. This flaw affects Linux kernel versions prior to 5.14-rc7. | ||||
| CVE-2021-3652 | 2 Port389, Redhat | 4 389-ds-base, Directory Server, Enterprise Linux and 1 more | 2024-11-21 | 6.5 Medium |
| A flaw was found in 389-ds-base. If an asterisk is imported as password hashes, either accidentally or maliciously, then instead of being inactive, any password will successfully match during authentication. This flaw allows an attacker to successfully authenticate as a user whose password was disabled. | ||||
| CVE-2021-3640 | 6 Canonical, Debian, Fedoraproject and 3 more | 23 Ubuntu Linux, Debian Linux, Fedora and 20 more | 2024-11-21 | 7.0 High |
| A flaw use-after-free in function sco_sock_sendmsg() of the Linux kernel HCI subsystem was found in the way user calls ioct UFFDIO_REGISTER or other way triggers race condition of the call sco_conn_del() together with the call sco_sock_sendmsg() with the expected controllable faulting memory page. A privileged local user could use this flaw to crash the system or escalate their privileges on the system. | ||||
| CVE-2021-3621 | 2 Fedoraproject, Redhat | 10 Fedora, Sssd, Enterprise Linux and 7 more | 2024-11-21 | 8.8 High |
| A flaw was found in SSSD, where the sssctl command was vulnerable to shell command injection via the logs-fetch and cache-expire subcommands. This flaw allows an attacker to trick the root user into running a specially crafted sssctl command, such as via sudo, to gain root access. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. | ||||
| CVE-2021-3609 | 3 Linux, Netapp, Redhat | 46 Linux Kernel, H300e, H300e Firmware and 43 more | 2024-11-21 | 7.0 High |
| .A flaw was found in the CAN BCM networking protocol in the Linux kernel, where a local attacker can abuse a flaw in the CAN subsystem to corrupt memory, crash the system or escalate privileges. This race condition in net/can/bcm.c in the Linux kernel allows for local privilege escalation to root. | ||||
| CVE-2021-3570 | 4 Debian, Fedoraproject, Linuxptp Project and 1 more | 8 Debian Linux, Fedora, Linuxptp and 5 more | 2024-11-21 | 8.8 High |
| A flaw was found in the ptp4l program of the linuxptp package. A missing length check when forwarding a PTP message between ports allows a remote attacker to cause an information leak, crash, or potentially remote code execution. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. This flaw affects linuxptp versions before 3.1.1, before 2.0.1, before 1.9.3, before 1.8.1, before 1.7.1, before 1.6.1 and before 1.5.1. | ||||
| 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-2021-3514 | 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-2021-3480 | 3 Fedoraproject, Redhat, Slapi-nis Project | 4 Fedora, Enterprise Linux, Rhel Eus and 1 more | 2024-11-21 | 7.5 High |
| A flaw was found in slapi-nis in versions before 0.56.7. A NULL pointer dereference during the parsing of the Binding DN could allow an unauthenticated attacker to crash the 389-ds-base directory server. The highest threat from this vulnerability is to system availability. | ||||
| CVE-2021-3449 | 13 Checkpoint, Debian, Fedoraproject and 10 more | 172 Multi-domain Management, Multi-domain Management Firmware, Quantum Security Gateway and 169 more | 2024-11-21 | 5.9 Medium |
| An OpenSSL TLS server may crash if sent a maliciously crafted renegotiation ClientHello message from a client. If a TLSv1.2 renegotiation ClientHello omits the signature_algorithms extension (where it was present in the initial ClientHello), but includes a signature_algorithms_cert extension then a NULL pointer dereference will result, leading to a crash and a denial of service attack. A server is only vulnerable if it has TLSv1.2 and renegotiation enabled (which is the default configuration). OpenSSL TLS clients are not impacted by this issue. All OpenSSL 1.1.1 versions are affected by this issue. Users of these versions should upgrade to OpenSSL 1.1.1k. OpenSSL 1.0.2 is not impacted by this issue. Fixed in OpenSSL 1.1.1k (Affected 1.1.1-1.1.1j). | ||||
| CVE-2021-3421 | 3 Fedoraproject, Redhat, Rpm | 4 Fedora, Enterprise Linux, Rhel Eus and 1 more | 2024-11-21 | 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-2021-3393 | 2 Postgresql, Redhat | 5 Postgresql, Enterprise Linux, Rhel Eus and 2 more | 2024-11-21 | 4.3 Medium |
| An information leak was discovered in postgresql in versions before 13.2, before 12.6 and before 11.11. A user having UPDATE permission but not SELECT permission to a particular column could craft queries which, under some circumstances, might disclose values from that column in error messages. An attacker could use this flaw to obtain information stored in a column they are allowed to write but not read. | ||||
| 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-2021-38575 | 3 Insyde, Redhat, Tianocore | 5 Kernel, Enterprise Linux, Rhel Eus and 2 more | 2024-11-21 | 8.1 High |
| NetworkPkg/IScsiDxe has remotely exploitable buffer overflows. | ||||
| CVE-2021-38509 | 3 Debian, Mozilla, Redhat | 6 Debian Linux, Firefox, Firefox Esr and 3 more | 2024-11-21 | 4.3 Medium |
| Due to an unusual sequence of attacker-controlled events, a Javascript alert() dialog with arbitrary (although unstyled) contents could be displayed over top an uncontrolled webpage of the attacker's choosing. This vulnerability affects Firefox < 94, Thunderbird < 91.3, and Firefox ESR < 91.3. | ||||
| CVE-2021-38508 | 3 Debian, Mozilla, Redhat | 6 Debian Linux, Firefox, Firefox Esr and 3 more | 2024-11-21 | 4.3 Medium |
| By displaying a form validity message in the correct location at the same time as a permission prompt (such as for geolocation), the validity message could have obscured the prompt, resulting in the user potentially being tricked into granting the permission. This vulnerability affects Firefox < 94, Thunderbird < 91.3, and Firefox ESR < 91.3. | ||||
| CVE-2021-38507 | 3 Debian, Mozilla, Redhat | 6 Debian Linux, Firefox, Firefox Esr and 3 more | 2024-11-21 | 6.5 Medium |
| The Opportunistic Encryption feature of HTTP2 (RFC 8164) allows a connection to be transparently upgraded to TLS while retaining the visual properties of an HTTP connection, including being same-origin with unencrypted connections on port 80. However, if a second encrypted port on the same IP address (e.g. port 8443) did not opt-in to opportunistic encryption; a network attacker could forward a connection from the browser to port 443 to port 8443, causing the browser to treat the content of port 8443 as same-origin with HTTP. This was resolved by disabling the Opportunistic Encryption feature, which had low usage. This vulnerability affects Firefox < 94, Thunderbird < 91.3, and Firefox ESR < 91.3. | ||||
| CVE-2021-38506 | 3 Debian, Mozilla, Redhat | 6 Debian Linux, Firefox, Firefox Esr and 3 more | 2024-11-21 | 4.3 Medium |
| Through a series of navigations, Firefox could have entered fullscreen mode without notification or warning to the user. This could lead to spoofing attacks on the browser UI including phishing. This vulnerability affects Firefox < 94, Thunderbird < 91.3, and Firefox ESR < 91.3. | ||||
| CVE-2021-38504 | 3 Debian, Mozilla, Redhat | 6 Debian Linux, Firefox, Firefox Esr and 3 more | 2024-11-21 | 8.8 High |
| When interacting with an HTML input element's file picker dialog with webkitdirectory set, a use-after-free could have resulted, leading to memory corruption and a potentially exploitable crash. This vulnerability affects Firefox < 94, Thunderbird < 91.3, and Firefox ESR < 91.3. | ||||
| CVE-2021-38503 | 3 Debian, Mozilla, Redhat | 6 Debian Linux, Firefox, Firefox Esr and 3 more | 2024-11-21 | 10.0 Critical |
