A vulnerability was discovered in SPICE before 0.13.90 in the server's protocol handling. An attacker able to connect to the SPICE server could send crafted messages which would cause the process to crash.
A heap buffer overflow flaw was found in QEMU's Cirrus CLGD 54xx VGA emulator's VNC display driver support before 2.9; the issue could occur when a VNC client attempted to update its display after a VGA operation is performed by a guest. A privileged user/process inside a guest could use this flaw to crash the QEMU process or, potentially, execute arbitrary code on the host with privileges of the QEMU process.
A stack-based buffer overflow vulnerability was found in NBD server implementation in qemu before 2.11 allowing a client to request an export name of size up to 4096 bytes, which in fact should be limited to 256 bytes, causing an out-of-bounds stack write in the qemu process. If NBD server requires TLS, the attacker cannot trigger the buffer overflow without first successfully negotiating TLS.
A vulnerability was discovered in SPICE before 0.13.90 in the server's protocol handling. An authenticated attacker could send crafted messages to the SPICE server causing a heap overflow leading to a crash or possible code execution.
Privilege escalation flaws were found in the Red Hat initialization scripts of PostgreSQL. An attacker with access to the postgres user account could use these flaws to obtain root access on the server machine.
A missing patch for a stack-based buffer overflow in findTable() was found in Red Hat version of liblouis before 2.5.4. An attacker could cause a denial of service condition or potentially even arbitrary code execution.
It was found that jenkins-ssh-slaves-plugin before version 1.15 did not perform host key verification, thereby enabling Man-in-the-Middle attacks.
It was found that the Active Directory Plugin for Jenkins up to and including version 2.2 did not verify certificates of the Active Directory server, thereby enabling Man-in-the-Middle attacks.
It was found that the use of Pipeline: Classpath Step Jenkins plugin enables a bypass of the Script Security sandbox for users with SCM commit access, as well as users with e.g. Job/Configure permission in Jenkins.
It was found that there were no permission checks performed in the Distributed Fork plugin before and including 1.5.0 for Jenkins that provides the dist-fork CLI command beyond the basic check for Overall/Read permission, allowing anyone with that permission to run arbitrary shell commands on all connected nodes.
It was found that subscription-manager's DBus interface before 1.19.4 let unprivileged user access the com.redhat.RHSM1.Facts.GetFacts and com.redhat.RHSM1.Config.Set methods. An unprivileged local attacker could use these methods to gain access to private information, or launch a privilege escalation attack.
A race condition was found in util-linux before 2.32.1 in the way su handled the management of child processes. A local authenticated attacker could use this flaw to kill other processes with root privileges under specific conditions.
A flaw was found in the Linux kernel's handling of clearing SELinux attributes on /proc/pid/attr files before 4.9.10. An empty (null) write to this file can crash the system by causing the system to attempt to access unmapped kernel memory.
Quick emulator (QEMU) before 2.8 built with the Cirrus CLGD 54xx VGA Emulator support is vulnerable to an out-of-bounds access issue. The issue could occur while copying VGA data in cirrus_bitblt_cputovideo. A privileged user inside guest could use this flaw to crash the QEMU process OR potentially execute arbitrary code on host with privileges of the QEMU process.
It was discovered that libICE before 1.0.9-8 used a weak entropy to generate keys. A local attacker could potentially use this flaw for session hijacking using the information available from the process list.
curl before 7.53.0 has an incorrect TLS Certificate Status Request extension feature that asks for a fresh proof of the server's certificate's validity in the code that checks for a test success or failure. It ends up always thinking there's valid proof, even when there is none or if the server doesn't support the TLS extension in question. This could lead to users not detecting when a server's certificate goes invalid or otherwise be mislead that the server is in a better shape than it is in reality. This flaw also exists in the command line tool (--cert-status).
A logic error in valid_role() in CloudForms role validation before 220.127.116.11 could allow a tenant administrator to create groups with a higher privilege level than the tenant administrator should have. This would allow an attacker with tenant administration access to elevate privileges.
An out-of-bounds memory access issue was found in Quick Emulator (QEMU) before 1.7.2 in the VNC display driver. This flaw could occur while refreshing the VNC display surface area in the 'vnc_refresh_server_surface'. A user inside a guest could use this flaw to crash the QEMU process.
It was found that the Linux kernel's Datagram Congestion Control Protocol (DCCP) implementation before 18.104.22.168 used the IPv4-only inet_sk_rebuild_header() function for both IPv4 and IPv6 DCCP connections, which could result in memory corruptions. A remote attacker could use this flaw to crash the system.
It was found that when Keycloak before 2.5.5 receives a Logout request with a Extensions in the middle of the request, the SAMLSloRequestParser.parse() method ends in a infinite loop. An attacker could use this flaw to conduct denial of service attacks.
