CVE-2021-3694 2 Debian, Ledgersmb 2 Debian Linux, Ledgersmb 2024-08-03 8.2 High
LedgerSMB does not sufficiently HTML-encode error messages sent to the browser. By sending a specially crafted URL to an authenticated user, this flaw can be abused for remote code execution and information disclosure.
CVE-2021-3713 2 Debian, Qemu 2 Debian Linux, Qemu 2024-08-03 7.4 High
An out-of-bounds write flaw was found in the UAS (USB Attached SCSI) device emulation of QEMU in versions prior to 6.2.0-rc0. The device uses the guest supplied stream number unchecked, which can lead to out-of-bounds access to the UASDevice->data3 and UASDevice->status3 fields. A malicious guest user could use this flaw to crash QEMU or potentially achieve code execution with the privileges of the QEMU process on the host.
CVE-2021-3657 4 Debian, Fedoraproject, Isync Project and 1 more 4 Debian Linux, Fedora, Isync and 1 more 2024-08-03 9.8 Critical
A flaw was found in mbsync versions prior to 1.4.4. Due to inadequate handling of extremely large (>=2GiB) IMAP literals, malicious or compromised IMAP servers, and hypothetically even external email senders, could cause several different buffer overflows, which could conceivably be exploited for remote code execution.
CVE-2021-3598 3 Debian, Openexr, Redhat 3 Debian Linux, Openexr, Enterprise Linux 2024-08-03 5.5 Medium
There's a flaw in OpenEXR's ImfDeepScanLineInputFile functionality in versions prior to 3.0.5. An attacker who is able to submit a crafted file to an application linked with OpenEXR could cause an out-of-bounds read. The greatest risk from this flaw is to application availability.
CVE-2021-3596 4 Debian, Fedoraproject, Imagemagick and 1 more 4 Debian Linux, Fedora, Imagemagick and 1 more 2024-08-03 6.5 Medium
A NULL pointer dereference flaw was found in ImageMagick in versions prior to 7.0.10-31 in ReadSVGImage() in coders/svg.c. This issue is due to not checking the return value from libxml2's xmlCreatePushParserCtxt() and uses the value directly, which leads to a crash and segmentation fault.
CVE-2021-3693 2 Debian, Ledgersmb 2 Debian Linux, Ledgersmb 2024-08-03 8.8 High
LedgerSMB does not check the origin of HTML fragments merged into the browser's DOM. By sending a specially crafted URL to an authenticated user, this flaw can be abused for remote code execution and information disclosure.
CVE-2021-3671 3 Debian, Netapp, Samba 5 Debian Linux, Management Services For Element Software, Management Services For Netapp Hci and 2 more 2024-08-03 6.5 Medium
A null pointer de-reference was found in the way samba kerberos server handled missing sname in TGS-REQ (Ticket Granting Server - Request). An authenticated user could use this flaw to crash the samba server.
CVE-2021-3624 2 Dcraw Project, Debian 2 Dcraw, Debian Linux 2024-08-03 7.8 High
There is an integer overflow vulnerability in dcraw. When the victim runs dcraw with a maliciously crafted X3F input image, arbitrary code may be executed in the victim's system.
CVE-2021-3669 5 Debian, Fedoraproject, Ibm and 2 more 24 Debian Linux, Fedora, Spectrum Copy Data Management and 21 more 2024-08-03 5.5 Medium
A flaw was found in the Linux kernel. Measuring usage of the shared memory does not scale with large shared memory segment counts which could lead to resource exhaustion and DoS.
CVE-2021-3655 3 Debian, Linux, Redhat 3 Debian Linux, Linux Kernel, Enterprise Linux 2024-08-03 3.3 Low
A vulnerability was found in the Linux kernel in versions prior to v5.14-rc1. Missing size validations on inbound SCTP packets may allow the kernel to read uninitialized memory.
CVE-2021-3593 4 Debian, Fedoraproject, Libslirp Project and 1 more 4 Debian Linux, Fedora, Libslirp and 1 more 2024-08-03 3.8 Low
An invalid pointer initialization issue was found in the SLiRP networking implementation of QEMU. The flaw exists in the udp6_input() function and could occur while processing a udp packet that is smaller than the size of the 'udphdr' structure. This issue may lead to out-of-bounds read access or indirect host memory disclosure to the guest. The highest threat from this vulnerability is to data confidentiality. This flaw affects libslirp versions prior to 4.6.0.
CVE-2021-3630 3 Debian, Djvulibre Project, Fedoraproject 3 Debian Linux, Djvulibre, Fedora 2024-08-03 5.5 Medium
An out-of-bounds write vulnerability was found in DjVuLibre in DJVU::DjVuTXT::decode() in DjVuText.cpp via a crafted djvu file which may lead to crash and segmentation fault. This flaw affects DjVuLibre versions prior to 3.5.28.
CVE-2021-3607 3 Debian, Fedoraproject, Qemu 3 Debian Linux, Fedora, Qemu 2024-08-03 6.0 Medium
An integer overflow was found in the QEMU implementation of VMWare's paravirtual RDMA device in versions prior to 6.1.0. The issue occurs while handling a "PVRDMA_REG_DSRHIGH" write from the guest due to improper input validation. This flaw allows a privileged guest user to make QEMU allocate a large amount of memory, resulting in a denial of service. The highest threat from this vulnerability is to system availability.
CVE-2021-3578 3 Debian, Fedoraproject, Isync Project 3 Debian Linux, Fedora, Isync 2024-08-03 7.8 High
A flaw was found in mbsync before v1.3.6 and v1.4.2, where an unchecked pointer cast allows a malicious or compromised server to write an arbitrary integer value past the end of a heap-allocated structure by issuing an unexpected APPENDUID response. This could be plausibly exploited for remote code execution on the client.
CVE-2021-3640 6 Canonical, Debian, Fedoraproject and 3 more 23 Ubuntu Linux, Debian Linux, Fedora and 20 more 2024-08-03 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-2021-3682 3 Debian, Qemu, Redhat 4 Debian Linux, Qemu, Advanced Virtualization and 1 more 2024-08-03 8.5 High
A flaw was found in the USB redirector device emulation of QEMU in versions prior to 6.1.0-rc2. It occurs when dropping packets during a bulk transfer from a SPICE client due to the packet queue being full. A malicious SPICE client could use this flaw to make QEMU call free() with faked heap chunk metadata, resulting in a crash of QEMU or potential code execution with the privileges of the QEMU process on the host.
CVE-2021-3731 2 Debian, Ledgersmb 2 Debian Linux, Ledgersmb 2024-08-03 5.9 Medium
LedgerSMB does not sufficiently guard against being wrapped by other sites, making it vulnerable to 'clickjacking'. This allows an attacker to trick a targetted user to execute unintended actions.
CVE-2021-3546 2 Debian, Qemu 2 Debian Linux, Qemu 2024-08-03 8.2 High
An out-of-bounds write vulnerability was found in the virtio vhost-user GPU device (vhost-user-gpu) of QEMU in versions up to and including 6.0. The flaw occurs while processing the 'VIRTIO_GPU_CMD_GET_CAPSET' command from the guest. It could allow a privileged guest user to crash the QEMU process on the host, resulting in a denial of service condition, or potential code execution with the privileges of the QEMU process.
CVE-2021-3527 3 Debian, Qemu, Redhat 3 Debian Linux, Qemu, Enterprise Linux 2024-08-03 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-2021-3634 6 Debian, Fedoraproject, Libssh and 3 more 7 Debian Linux, Fedora, Libssh and 4 more 2024-08-03 6.5 Medium
A flaw has been found in libssh in versions prior to 0.9.6. The SSH protocol keeps track of two shared secrets during the lifetime of the session. One of them is called secret_hash and the other session_id. Initially, both of them are the same, but after key re-exchange, previous session_id is kept and used as an input to new secret_hash. Historically, both of these buffers had shared length variable, which worked as long as these buffers were same. But the key re-exchange operation can also change the key exchange method, which can be based on hash of different size, eventually creating "secret_hash" of different size than the session_id has. This becomes an issue when the session_id memory is zeroed or when it is used again during second key re-exchange.
