Redhat Enterprise Linux vulnerabilities

CVE-2023-32233 [HIGH] CWE-416 CVE-2023-32233: In the Linux kernel through 6.3.1, a use-after-free in Netfilter nf_tables when processing batch req In the Linux kernel through 6.3.1, a use-after-free in Netfilter nf_tables when processing batch requests can be abused to perform arbitrary read and write operations on kernel memory. Unprivileged local users can obtain root privileges. This occurs because anonymous sets are mishandled.

CVE-2023-3269 [HIGH] CWE-416 CVE-2023-3269: A vulnerability exists in the memory management subsystem of the Linux kernel. The lock handling for A vulnerability exists in the memory management subsystem of the Linux kernel. The lock handling for accessing and updating virtual memory areas (VMAs) is incorrect, leading to use-after-free problems. This issue can be successfully exploited to execute arbitrary kernel code, escalate containers, and gain root privileges.

CVE-2015-3636 [MEDIUM] CVE-2015-3636: The ping_unhash function in net/ipv4/ping.c in the Linux kernel before 4.0.3 does not initialize a c The ping_unhash function in net/ipv4/ping.c in the Linux kernel before 4.0.3 does not initialize a certain list data structure during an unhash operation, which allows local users to gain privileges or cause a denial of service (use-after-free and system crash) by leveraging the ability to make a SOCK_DGRAM socket system call for the IPPROTO_ICMP or IPPROTO_I

CVE-2022-35653 [MEDIUM] CWE-79 CVE-2022-35653: A reflected XSS issue was identified in the LTI module of Moodle. The vulnerability exists due to in A reflected XSS issue was identified in the LTI module of Moodle. The vulnerability exists due to insufficient sanitization of user-supplied data in the LTI module. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website to steal potentiall

CVE-2019-6109 [MEDIUM] CWE-116 CVE-2019-6109: An issue was discovered in OpenSSH 7.9. Due to missing character encoding in the progress display, a An issue was discovered in OpenSSH 7.9. Due to missing character encoding in the progress display, a malicious server (or Man-in-The-Middle attacker) can employ crafted object names to manipulate the client output, e.g., by using ANSI control codes to hide additional files being transferred. This affects refresh_progress_meter() in progressmeter.c.

CVE-2018-20685 [MEDIUM] CWE-863 CVE-2018-20685: In OpenSSH 7.9, scp.c in the scp client allows remote SSH servers to bypass intended access restrict In OpenSSH 7.9, scp.c in the scp client allows remote SSH servers to bypass intended access restrictions via the filename of . or an empty filename. The impact is modifying the permissions of the target directory on the client side.

CVE-2018-11763 [MEDIUM] CVE-2018-11763: In Apache HTTP Server 2.4.17 to 2.4.34, by sending continuous, large SETTINGS frames a client can oc In Apache HTTP Server 2.4.17 to 2.4.34, by sending continuous, large SETTINGS frames a client can occupy a connection, server thread and CPU time without any connection timeout coming to effect. This affects only HTTP/2 connections. A possible mitigation is to not enable the h2 protocol.

CVE-2018-10933 [CRITICAL] CWE-592 CVE-2018-10933: A vulnerability was found in libssh's server-side state machine before versions 0.7.6 and 0.8.4. A m A vulnerability was found in libssh's server-side state machine before versions 0.7.6 and 0.8.4. A malicious client could create channels without first performing authentication, resulting in unauthorized access.

CVE-2013-4854 [HIGH] CVE-2013-4854: The RFC 5011 implementation in rdata.c in ISC BIND 9.7.x and 9.8.x before 9.8.5-P2, 9.8.6b1, 9.9.x b The RFC 5011 implementation in rdata.c in ISC BIND 9.7.x and 9.8.x before 9.8.5-P2, 9.8.6b1, 9.9.x before 9.9.3-P2, and 9.9.4b1, and DNSco BIND 9.9.3-S1 before 9.9.3-S1-P1 and 9.9.4-S1b1, allows remote attackers to cause a denial of service (assertion failure and named daemon exit) via a query with a malformed RDATA section that is not properly handled during c

CVE-2015-0240 [CRITICAL] CWE-17 CVE-2015-0240: The Netlogon server implementation in smbd in Samba 3.5.x and 3.6.x before 3.6.25, 4.0.x before 4.0. The Netlogon server implementation in smbd in Samba 3.5.x and 3.6.x before 3.6.25, 4.0.x before 4.0.25, 4.1.x before 4.1.17, and 4.2.x before 4.2.0rc5 performs a free operation on an uninitialized stack pointer, which allows remote attackers to execute arbitrary code via crafted Netlogon packets that use the ServerPasswordSet RPC API, as demonstrated

CVE-2016-2183 [HIGH] CWE-200 CVE-2016-2183: The DES and Triple DES ciphers, as used in the TLS, SSH, and IPSec protocols and other protocols and The DES and Triple DES ciphers, as used in the TLS, SSH, and IPSec protocols and other protocols and products, have a birthday bound of approximately four billion blocks, which makes it easier for remote attackers to obtain cleartext data via a birthday attack against a long-duration encrypted session, as demonstrated by an HTTPS session using Triple DE

CVE-2019-14287 [HIGH] CWE-755 CVE-2019-14287: In Sudo before 1.8.28, an attacker with access to a Runas ALL sudoer account can bypass certain poli In Sudo before 1.8.28, an attacker with access to a Runas ALL sudoer account can bypass certain policy blacklists and session PAM modules, and can cause incorrect logging, by invoking sudo with a crafted user ID. For example, this allows bypass of !root configuration, and USER= logging, for a "sudo -u \#$((0xffffffff))" command.

CVE-2018-11235 [HIGH] CWE-22 CVE-2018-11235: In Git before 2.13.7, 2.14.x before 2.14.4, 2.15.x before 2.15.2, 2.16.x before 2.16.4, and 2.17.x b In Git before 2.13.7, 2.14.x before 2.14.4, 2.15.x before 2.15.2, 2.16.x before 2.16.4, and 2.17.x before 2.17.1, remote code execution can occur. With a crafted .gitmodules file, a malicious project can execute an arbitrary script on a machine that runs "git clone --recurse-submodules" because submodule "names" are obtained from this file, and then ap

CVE-2017-15118 [CRITICAL] CWE-121 CVE-2017-15118: A stack-based buffer overflow vulnerability was found in NBD server implementation in qemu before 2. 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 overf

CVE-2014-4650 [CRITICAL] CWE-22 CVE-2014-4650: The CGIHTTPServer module in Python 2.7.5 and 3.3.4 does not properly handle URLs in which URL encodi The CGIHTTPServer module in Python 2.7.5 and 3.3.4 does not properly handle URLs in which URL encoding is used for path separators, which allows remote attackers to read script source code or conduct directory traversal attacks and execute unintended code via a crafted character sequence, as demonstrated by a %2f separator.
