jboss-remoting: Threads hold up forever in the EJB server by suppressing the ack from an EJB client

A flaw was found in jboss-remoting. A malicious attacker could cause threads to hold up forever in the EJB server by writing a sequence of bytes corresponding to the expected messages of a successful EJB client request, but omitting the ACK messages, or just tamper with jboss-remoting code,...

kernel: performance counters race condition use-after-free

A flaw was found in the Linux kernel. A use-after-free memory flaw was found in the perf subsystem allowing a local attacker with permission to monitor perf events to corrupt memory and possibly escalate privileges. The highest threat from this vulnerability is to data confidentiality and integri...

CVE-2021-28210

A flaw was found in edk2. An unlimited recursion in DxeCore may allow an attacker to corrupt the system memory. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability...

CVE-2021-28211

A flaw was found in edk2. A possible heap corruption in LzmaUefiDecompressGetInfo function may allow an attacker to execute code on the system. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability...

openvswitch: limitation in the OVS packet parsing in userspace leads to DoS

A vulnerability was found in openvswitch. A limitation in the implementation of userspace packet parsing can allow a malicious user to send a specially crafted packet causing the resulting megaflow in the kernel to be too wide, potentially causing a denial of service. The highest threat from this...

Keycloak Missing authentication for critical function

A flaw was found in Keycloak 12.0.0 where re-authentication does not occur while updating the password. This flaw allows an attacker to take over an account if they can obtain temporary, physical access to a user’s browser. The highest threat from this vulnerability is to confidentiality,...

A flaw was found in grub2 in versions prior to 2.06 where it incorrectly enables the usage of the ACPI command when Secure Boot is enabled. This flaw allows an attacker with privileged access to craft a Secondary System Description Table (SSDT) containing code to overwrite the Linux kernel lockdown variable content directly into memory. The table is further loaded and executed by the kernel defeating its Secure Boot lockdown and allowing the attacker to load unsigned code. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

CVE-2021-20271

A flaw was found in RPM's signature check functionality when reading a package file. This flaw allows an attacker who can convince a victim to install a seemingly verifiable package, whose signature header was modified, to cause RPM database corruption and execute code. The highest threat from th...

CVE-2021-20266

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. Mitigation If using the headerCheck and headerImport APIs in your software, do not run...

CVE-2021-20284

A flaw was found in GNU Binutils 2.35.1, where there is a heap-based buffer overflow in bfdelfslurpsecondaryrelocsection in elf.c due to the number of symbols not calculated correctly. The highest threat from this vulnerability is to system availability...

A flaw was found in grub2 in versions prior to 2.06. Variable names present are expanded in the supplied command line into their corresponding variable contents using a 1kB stack buffer for temporary storage without sufficient bounds checking. If the function is called with a command line that references a variable with a sufficiently large payload it is possible to overflow the stack buffer corrupt the stack frame and control execution which could also circumvent Secure Boot protections. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

A flaw was found in grub2 in versions prior to 2.06. The option parser allows an attacker to write past the end of a heap-allocated buffer by calling certain commands with a large number of specific short forms of options. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
