CVE-2021-20266 3 Fedoraproject, Redhat, Rpm 3 Fedora, Enterprise Linux, Rpm 2024-11-21 4.9 Medium
A flaw was found in RPM's hdrblobInit() in lib/header.c. This flaw allows an attacker who can modify the rpmdb to cause an out-of-bounds read. The highest threat from this vulnerability is to system availability.
CVE-2021-20254 4 Debian, Fedoraproject, Redhat and 1 more 9 Debian Linux, Fedora, Enterprise Linux and 6 more 2024-11-21 6.8 Medium
A flaw was found in samba. The Samba smbd file server must map Windows group identities (SIDs) into unix group ids (gids). The code that performs this had a flaw that could allow it to read data beyond the end of the array in the case where a negative cache entry had been added to the mapping cache. This could cause the calling code to return those values into the process token that stores the group membership for a user. The highest threat from this vulnerability is to data confidentiality and integrity.
CVE-2021-20236 3 Fedoraproject, Redhat, Zeromq 4 Fedora, Ceph Storage, Enterprise Linux and 1 more 2024-11-21 9.8 Critical
A flaw was found in the ZeroMQ server in versions before 4.3.3. This flaw allows a malicious client to cause a stack buffer overflow on the server by sending crafted topic subscription requests and then unsubscribing. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
CVE-2021-20235 1 Zeromq 1 Libzmq 2024-11-21 8.1 High
There's a flaw in the zeromq server in versions before 4.3.3 in src/decoder_allocators.hpp. The decoder static allocator could have its sized changed, but the buffer would remain the same as it is a static buffer. A remote, unauthenticated attacker who sends a crafted request to the zeromq server could trigger a buffer overflow WRITE of arbitrary data if CURVE/ZAP authentication is not enabled. The greatest impact of this flaw is to application availability, data integrity, and confidentiality.
CVE-2021-20221 3 Debian, Qemu, Redhat 4 Debian Linux, Qemu, Advanced Virtualization and 1 more 2024-11-21 6.0 Medium
An out-of-bounds heap buffer access issue was found in the ARM Generic Interrupt Controller emulator of QEMU up to and including qemu 4.2.0on aarch64 platform. The issue occurs because while writing an interrupt ID to the controller memory area, it is not masked to be 4 bits wide. It may lead to the said issue while updating controller state fields and their subsequent processing. A privileged guest user may use this flaw to crash the QEMU process on the host resulting in DoS scenario.
CVE-2021-20177 1 Linux 1 Linux Kernel 2024-11-21 4.4 Medium
A flaw was found in the Linux kernel's implementation of string matching within a packet. A privileged user (with root or CAP_NET_ADMIN) when inserting iptables rules could insert a rule which can panic the system. Kernel before kernel 5.5-rc1 is affected.
CVE-2021-20166 1 Netgear 2 Rax43, Rax43 Firmware 2024-11-21 8.8 High
Netgear RAX43 version 1.0.3.96 contains a buffer overrun vulnerability. The URL parsing functionality in the cgi-bin endpoint of the router containers a buffer overrun issue that can redirection control flow of the applicaiton.
CVE-2021-20094 2 Siemens, Wibu 4 Pss Cape, Sicam 230, Sicam 230 Firmware and 1 more 2024-11-21 7.5 High
