| CVE-2021-3634 | 6 Debian, Fedoraproject, Libssh and 3 more | 7 Debian Linux, Fedora, Libssh and 4 more | 2024-11-21 | 4.0 MEDIUM | 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. | |||||
| CVE-2021-3630 | 3 Debian, Djvulibre Project, Fedoraproject | 3 Debian Linux, Djvulibre, Fedora | 2024-11-21 | 4.3 MEDIUM | 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-2021-3623 | 3 Fedoraproject, Libtpms Project, Redhat | 3 Fedora, Libtpms, Enterprise Linux | 2024-11-21 | 3.6 LOW | 6.1 MEDIUM |
| A flaw was found in libtpms. The flaw can be triggered by specially-crafted TPM 2 command packets containing illegal values and may lead to an out-of-bounds access when the volatile state of the TPM 2 is marshalled/written or unmarshalled/read. The highest threat from this vulnerability is to system availability. | |||||
| CVE-2021-3622 | 2 Fedoraproject, Redhat | 4 Fedora, Enterprise Linux, Enterprise Linux Workstation and 1 more | 2024-11-21 | 4.3 MEDIUM | 4.3 MEDIUM |
| A flaw was found in the hivex library. This flaw allows an attacker to input a specially crafted Windows Registry (hive) file, which would cause hivex to recursively call the _get_children() function, leading to a stack overflow. The highest threat from this vulnerability is to system availability. | |||||
| CVE-2021-3621 | 2 Fedoraproject, Redhat | 8 Fedora, Sssd, Enterprise Linux and 5 more | 2024-11-21 | 9.3 HIGH | 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-2021-3618 | 5 Debian, F5, Fedoraproject and 2 more | 5 Debian Linux, Nginx, Fedora and 2 more | 2024-11-21 | 5.8 MEDIUM | 7.4 HIGH |
| ALPACA is an application layer protocol content confusion attack, exploiting TLS servers implementing different protocols but using compatible certificates, such as multi-domain or wildcard certificates. A MiTM attacker having access to victim's traffic at the TCP/IP layer can redirect traffic from one subdomain to another, resulting in a valid TLS session. This breaks the authentication of TLS and cross-protocol attacks may be possible where the behavior of one protocol service may compromise the other at the application layer. | |||||
| CVE-2021-3612 | 6 Debian, Fedoraproject, Linux and 3 more | 26 Debian Linux, Fedora, Linux Kernel and 23 more | 2024-11-21 | 7.2 HIGH | 7.8 HIGH |
| An out-of-bounds memory write flaw was found in the Linux kernel's joystick devices subsystem in versions before 5.9-rc1, in the way the user calls ioctl JSIOCSBTNMAP. This flaw allows a local user to crash the system or possibly escalate their privileges on the system. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. | |||||
| CVE-2021-3610 | 3 Fedoraproject, Imagemagick, Redhat | 3 Fedora, Imagemagick, Enterprise Linux | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| A heap-based buffer overflow vulnerability was found in ImageMagick in versions prior to 7.0.11-14 in ReadTIFFImage() in coders/tiff.c. This issue is due to an incorrect setting of the pixel array size, which can lead to a crash and segmentation fault. | |||||
| CVE-2021-3608 | 3 Debian, Fedoraproject, Qemu | 3 Debian Linux, Fedora, Qemu | 2024-11-21 | 4.9 MEDIUM | 6.0 MEDIUM |
| A flaw 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 and may result in a crash of QEMU or cause undefined behavior due to the access of an uninitialized pointer. The highest threat from this vulnerability is to system availability. | |||||
| CVE-2021-3607 | 3 Debian, Fedoraproject, Qemu | 3 Debian Linux, Fedora, Qemu | 2024-11-21 | 4.9 MEDIUM | 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-2021-3603 | 2 Fedoraproject, Phpmailer Project | 2 Fedora, Phpmailer | 2024-11-21 | 6.8 MEDIUM | 8.1 HIGH |
| PHPMailer 6.4.1 and earlier contain a vulnerability that can result in untrusted code being called (if such code is injected into the host project's scope by other means). If the $patternselect parameter to validateAddress() is set to 'php' (the default, defined by PHPMailer::$validator), and the global namespace contains a function called php, it will be called in preference to the built-in validator of the same name. Mitigated in PHPMailer 6.5.0 by denying the use of simple strings as validator function names. | |||||
| CVE-2021-3600 | 4 Canonical, Fedoraproject, Linux and 1 more | 4 Ubuntu Linux, Fedora, Linux Kernel and 1 more | 2024-11-21 | N/A | 7.8 HIGH |
| It was discovered that the eBPF implementation in the Linux kernel did not properly track bounds information for 32 bit registers when performing div and mod operations. A local attacker could use this to possibly execute arbitrary code. | |||||
| CVE-2021-3596 | 4 Debian, Fedoraproject, Imagemagick and 1 more | 4 Debian Linux, Fedora, Imagemagick and 1 more | 2024-11-21 | 4.3 MEDIUM | 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-2021-3595 | 4 Debian, Fedoraproject, Libslirp Project and 1 more | 4 Debian Linux, Fedora, Libslirp and 1 more | 2024-11-21 | 2.1 LOW | 3.8 LOW |
| An invalid pointer initialization issue was found in the SLiRP networking implementation of QEMU. The flaw exists in the tftp_input() function and could occur while processing a udp packet that is smaller than the size of the 'tftp_t' 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. | |||||

| An invalid pointer initialization issue was found in the SLiRP networking implementation of QEMU. The flaw exists in the bootp_input() function and could occur while processing a udp packet that is smaller than the size of the 'bootp_t' structure. A malicious guest could use this flaw to leak 10 bytes of uninitialized heap memory from the host. The highest threat from this vulnerability is to data confidentiality.

| CVE-2021-3578 | 3 Debian, Fedoraproject, Isync Project | 3 Debian Linux, Fedora, Isync | 2024-11-21 | 7.2 HIGH | 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-2021-3575 | 3 Fedoraproject, Redhat, Uclouvain | 3 Fedora, Enterprise Linux, Openjpeg | 2024-11-21 | 6.8 MEDIUM | 7.8 HIGH |
| A heap-based buffer overflow was found in openjpeg in color.c:379:42 in sycc420_to_rgb when decompressing a crafted .j2k file. An attacker could use this to execute arbitrary code with the permissions of the application compiled against openjpeg. | |||||
