CVE-2021-20277 4 Debian, Fedoraproject, Redhat and 1 more 8 Debian Linux, Fedora, Enterprise Linux and 5 more 2024-11-21 7.5 High
A flaw was found in Samba's libldb. Multiple, consecutive leading spaces in an LDAP attribute can lead to an out-of-bounds memory write, leading to a crash of the LDAP server process handling the request. The highest threat from this vulnerability is to system availability.
CVE-2021-20276 2 Debian, Privoxy 2 Debian Linux, Privoxy 2024-11-21 7.5 High
A flaw was found in privoxy before 3.0.32. Invalid memory access with an invalid pattern passed to pcre_compile() may lead to denial of service.

A flaw was found in privoxy before 3.0.32. A invalid read of size two may occur in chunked_body_is_complete() leading to denial of service.
CVE-2021-20268 1 Linux 1 Linux Kernel 2024-11-21 7.8 High
An out-of-bounds access flaw was found in the Linux kernel's implementation of the eBPF code verifier in the way a user running the eBPF script calls dev_map_init_map or sock_map_alloc. This flaw allows a local user to crash the system or possibly escalate their privileges. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
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-2021-20239 3 Fedoraproject, Linux, Redhat 3 Fedora, Linux Kernel, Enterprise Linux 2024-11-21 3.3 Low
A flaw was found in the Linux kernel in versions before 5.4.92 in the BPF protocol. This flaw allows an attacker with a local account to leak information about kernel internal addresses. The highest threat from this vulnerability is to confidentiality.
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-2021-20224 1 Imagemagick 1 Imagemagick 2024-11-21 5.5 Medium
An integer overflow issue was discovered in ImageMagick's ExportIndexQuantum() function in MagickCore/quantum-export.c. Function calls to GetPixelIndex() could result in values outside the range of representable for the 'unsigned char'. When ImageMagick processes a crafted pdf file, this could lead to an undefined behaviour or a crash.
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-2021-20204 3 Debian, Fedoraproject, Getdata Project 3 Debian Linux, Fedora, Getdata 2024-11-21 9.8 Critical
A heap memory corruption problem (use after free) can be triggered in libgetdata v0.10.0 when processing maliciously crafted dirfile databases. This degrades the confidentiality, integrity and availability of third-party software that uses libgetdata as a library. This vulnerability may lead to arbitrary code execution or privilege escalation depending on input/skills of attacker.
CVE-2021-20203 3 Debian, Fedoraproject, Qemu 3 Debian Linux, Fedora, Qemu 2024-11-21 3.2 Low
An integer overflow issue was found in the vmxnet3 NIC emulator of the QEMU for versions up to v5.2.0. It may occur if a guest was to supply invalid values for rx/tx queue size or other NIC parameters. A privileged guest user may use this flaw to crash the QEMU process on the host resulting in DoS scenario.
CVE-2021-20195 1 Redhat 1 Keycloak 2024-11-21 9.6 Critical
A flaw was found in keycloak in versions before 13.0.0. A Self Stored XSS attack vector escalating to a complete account takeover is possible due to user-supplied data fields not being properly encoded and Javascript code being used to process the data. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
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.
