Recent Red Hat Enterprise Linux Power Big Endian Security Vulnerabilities
A vulnerability was found in insights-client
CVE-2023-3972
7.8 - High
- November 01, 2023
A vulnerability was found in insights-client. This security issue occurs because of insecure file operations or unsafe handling of temporary files and directories that lead to local privilege escalation. Before the insights-client has been registered on the system by root, an unprivileged local user or attacker could create the /var/tmp/insights-client directory (owning the directory with read, write, and execute permissions) on the system. After the insights-client is registered by root, an attacker could then control the directory content that insights are using by putting malicious scripts into it and executing arbitrary code as root (trivially bypassing SELinux protections because insights processes are allowed to disable SELinux system-wide).
Exposure of Resource to Wrong Sphere
A vulnerability was found in subscription-manager that allows local privilege escalation due to inadequate authorization
CVE-2023-3899
7.8 - High
- August 23, 2023
A vulnerability was found in subscription-manager that allows local privilege escalation due to inadequate authorization. The D-Bus interface com.redhat.RHSM1 exposes a significant number of methods to all users that could change the state of the registration. By using the com.redhat.RHSM1.Config.SetAll() method, a low-privileged local user could tamper with the state of the registration, by unregistering the system or by changing the current entitlements. This flaw allows an attacker to set arbitrary configuration directives for /etc/rhsm/rhsm.conf, which can be abused to cause a local privilege escalation to an unconfined root.
AuthZ
A vulnerability was found in X.Org
CVE-2023-0494
7.8 - High
- March 27, 2023
A vulnerability was found in X.Org. This issue occurs due to a dangling pointer in DeepCopyPointerClasses that can be exploited by ProcXkbSetDeviceInfo() and ProcXkbGetDeviceInfo() to read and write into freed memory. This can lead to local privilege elevation on systems where the X server runs privileged and remote code execution for ssh X forwarding sessions.
Dangling pointer
A vulnerability was found in WebKit
CVE-2019-8720
8.8 - High
- March 06, 2023
A vulnerability was found in WebKit. The flaw is triggered when processing maliciously crafted web content that may lead to arbitrary code execution. Improved memory handling addresses the multiple memory corruption issues.
Buffer Overflow
sssd: libsss_certmap fails to sanitise certificate data used in LDAP filters
CVE-2022-4254
8.8 - High
- February 01, 2023
sssd: libsss_certmap fails to sanitise certificate data used in LDAP filters
A random memory access flaw was found in the Linux kernel's GPU i915 kernel driver functionality in the way a user may run malicious code on the GPU
CVE-2022-0330
7.8 - High
- March 25, 2022
A random memory access flaw was found in the Linux kernel's GPU i915 kernel driver functionality in the way a user may run malicious code on the GPU. This flaw allows a local user to crash the system or escalate their privileges on the system.
Improper Preservation of Permissions
A flaw was found in the KVM's AMD code for supporting SVM nested virtualization
CVE-2021-3656
8.8 - High
- March 04, 2022
A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when processing the VMCB (virtual machine control block) provided by the L1 guest to spawn/handle a nested guest (L2). Due to improper validation of the "virt_ext" field, this issue could allow a malicious L1 to disable both VMLOAD/VMSAVE intercepts and VLS (Virtual VMLOAD/VMSAVE) for the L2 guest. As a result, the L2 guest would be allowed to read/write physical pages of the host, resulting in a crash of the entire system, leak of sensitive data or potential guest-to-host escape.
AuthZ
The Samba vfs_fruit module uses extended file attributes (EA, xattr) to provide "
CVE-2021-44142
8.8 - High
- February 21, 2022
The Samba vfs_fruit module uses extended file attributes (EA, xattr) to provide "...enhanced compatibility with Apple SMB clients and interoperability with a Netatalk 3 AFP fileserver." Samba versions prior to 4.13.17, 4.14.12 and 4.15.5 with vfs_fruit configured allow out-of-bounds heap read and write via specially crafted extended file attributes. A remote attacker with write access to extended file attributes can execute arbitrary code with the privileges of smbd, typically root.
Out-of-bounds Read
A flaw was found in the way Samba, as an Active Directory Domain Controller, implemented Kerberos name-based authentication
CVE-2020-25719
7.2 - High
- February 18, 2022
A flaw was found in the way Samba, as an Active Directory Domain Controller, implemented Kerberos name-based authentication. The Samba AD DC, could become confused about the user a ticket represents if it did not strictly require a Kerberos PAC and always use the SIDs found within. The result could include total domain compromise.
Race Condition
A double-free was found in the way 389-ds-base handles virtual attributes context in persistent searches
CVE-2021-4091
7.5 - High
- February 18, 2022
A double-free was found in the way 389-ds-base handles virtual attributes context in persistent searches. An attacker could send a series of search requests, forcing the server to behave unexpectedly, and crash.
Double-free
A flaw was found in the way Samba maps domain users to local users
CVE-2020-25717
8.1 - High
- February 18, 2022
A flaw was found in the way Samba maps domain users to local users. An authenticated attacker could use this flaw to cause possible privilege escalation.
Improper Input Validation
A flaw was found in the way samba implemented SMB1 authentication
CVE-2016-2124
5.9 - Medium
- February 18, 2022
A flaw was found in the way samba implemented SMB1 authentication. An attacker could use this flaw to retrieve the plaintext password sent over the wire even if Kerberos authentication was required.
authentification
A local privilege escalation vulnerability was found on polkit's pkexec utility
CVE-2021-4034
7.8 - High
- January 28, 2022
A local privilege escalation vulnerability was found on polkit's pkexec utility. The pkexec application is a setuid tool designed to allow unprivileged users to run commands as privileged users according predefined policies. The current version of pkexec doesn't handle the calling parameters count correctly and ends trying to execute environment variables as commands. An attacker can leverage this by crafting environment variables in such a way it'll induce pkexec to execute arbitrary code. When successfully executed the attack can cause a local privilege escalation given unprivileged users administrative rights on the target machine.
Out-of-bounds Read
png_image_free in png.c in libpng 1.6.x before 1.6.37 has a use-after-free
CVE-2019-7317
5.3 - Medium
- February 04, 2019
png_image_free in png.c in libpng 1.6.x before 1.6.37 has a use-after-free because png_image_free_function is called under png_safe_execute.
Dangling pointer

CVE-2018-16881
7.5 - High
- January 25, 2019

CVE-2018-16866
3.3 - Low
- January 11, 2019

CVE-2015-3405
7.5 - High
- August 09, 2017
ntp-keygen in ntp 4.2.8px before 4.2.8p2-RC2 and 4.3.x before 4.3.12 does not generate MD5 keys with sufficient entropy on big endian machines when the lowest order byte of the temp variable is between 0x20 and 0x7f and not #, which might allow remote attackers to obtain the value of generated MD5 keys via a brute force attack with the 93 possible keys.
