CVE-2018-1302 3 Apache, Canonical, Netapp 6 Http Server, Ubuntu Linux, Clustered Data Ontap and 3 more 2021-06-06 4.3 MEDIUM 5.9 MEDIUM
When an HTTP/2 stream was destroyed after being handled, the Apache HTTP Server prior to version 2.4.30 could have written a NULL pointer potentially to an already freed memory. The memory pools maintained by the server make this vulnerability hard to trigger in usual configurations, the reporter and the team could not reproduce it outside debug builds, so it is classified as low risk.
CVE-2018-1283 5 Apache, Canonical, Debian and 2 more 8 Http Server, Ubuntu Linux, Debian Linux and 5 more 2021-06-06 3.5 LOW 5.3 MEDIUM
In Apache httpd 2.4.0 to 2.4.29, when mod_session is configured to forward its session data to CGI applications (SessionEnv on, not the default), a remote user may influence their content by using a "Session" header. This comes from the "HTTP_SESSION" variable name used by mod_session to forward its data to CGIs, since the prefix "HTTP_" is also used by the Apache HTTP Server to pass HTTP header fields, per CGI specifications.
CVE-2018-11763 5 Apache, Canonical, Netapp and 2 more 9 Http Server, Ubuntu Linux, Storage Automation Store and 6 more 2021-06-06 4.3 MEDIUM 5.9 MEDIUM
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-2015-0228 4 Apache, Apple, Canonical and 1 more 5 Http Server, Mac Os X, Mac Os X Server and 2 more 2021-06-06 5.0 MEDIUM N/A
The lua_websocket_read function in lua_request.c in the mod_lua module in the Apache HTTP Server through 2.4.12 allows remote attackers to cause a denial of service (child-process crash) by sending a crafted WebSocket Ping frame after a Lua script has called the wsupgrade function.
CVE-2017-15715 5 Apache, Canonical, Debian and 2 more 8 Http Server, Ubuntu Linux, Debian Linux and 5 more 2021-06-06 6.8 MEDIUM 8.1 HIGH
In Apache httpd 2.4.0 to 2.4.29, the expression specified in <FilesMatch> could match '$' to a newline character in a malicious filename, rather than matching only the end of the filename. This could be exploited in environments where uploads of some files are are externally blocked, but only by matching the trailing portion of the filename.
CVE-2017-15710 5 Apache, Canonical, Debian and 2 more 8 Http Server, Ubuntu Linux, Debian Linux and 5 more 2021-06-06 5.0 MEDIUM 7.5 HIGH
In Apache httpd 2.0.23 to 2.0.65, 2.2.0 to 2.2.34, and 2.4.0 to 2.4.29, mod_authnz_ldap, if configured with AuthLDAPCharsetConfig, uses the Accept-Language header value to lookup the right charset encoding when verifying the user's credentials. If the header value is not present in the charset conversion table, a fallback mechanism is used to truncate it to a two characters value to allow a quick retry (for example, 'en-US' is truncated to 'en'). A header value of less than two characters forces an out of bound write of one NUL byte to a memory location that is not part of the string. In the worst case, quite unlikely, the process would crash which could be used as a Denial of Service attack. In the more likely case, this memory is already reserved for future use and the issue has no effect at all.
CVE-2014-3583 3 Apache, Apple, Canonical 4 Http Server, Mac Os X, Os X Server and 1 more 2021-06-06 5.0 MEDIUM N/A
The handle_headers function in mod_proxy_fcgi.c in the mod_proxy_fcgi module in the Apache HTTP Server 2.4.10 allows remote FastCGI servers to cause a denial of service (buffer over-read and daemon crash) via long response headers.
CVE-2020-11984 7 Apache, Canonical, Debian and 4 more 13 Http Server, Ubuntu Linux, Debian Linux and 10 more 2021-06-06 7.5 HIGH 9.8 CRITICAL
Apache HTTP server 2.4.32 to 2.4.44 mod_proxy_uwsgi info disclosure and possible RCE
CVE-2018-17199 5 Apache, Canonical, Debian and 2 more 6 Http Server, Ubuntu Linux, Debian Linux and 3 more 2021-06-06 5.0 MEDIUM 7.5 HIGH
In Apache HTTP Server 2.4 release 2.4.37 and prior, mod_session checks the session expiry time before decoding the session. This causes session expiry time to be ignored for mod_session_cookie sessions since the expiry time is loaded when the session is decoded.
CVE-2019-0217 8 Apache, Canonical, Debian and 5 more 14 Http Server, Ubuntu Linux, Debian Linux and 11 more 2021-06-06 6.0 MEDIUM 7.5 HIGH
In Apache HTTP Server 2.4 release 2.4.38 and prior, a race condition in mod_auth_digest when running in a threaded server could allow a user with valid credentials to authenticate using another username, bypassing configured access control restrictions.
CVE-2019-0211 5 Apache, Canonical, Debian and 2 more 5 Http Server, Ubuntu Linux, Debian Linux and 2 more 2021-06-06 7.2 HIGH 7.8 HIGH
In Apache HTTP Server 2.4 releases 2.4.17 to 2.4.38, with MPM event, worker or prefork, code executing in less-privileged child processes or threads (including scripts executed by an in-process scripting interpreter) could execute arbitrary code with the privileges of the parent process (usually root) by manipulating the scoreboard. Non-Unix systems are not affected.
CVE-2018-6789 3 Canonical, Debian, Exim 3 Ubuntu Linux, Debian Linux, Exim 2021-06-03 7.5 HIGH 9.8 CRITICAL
An issue was discovered in the base64d function in the SMTP listener in Exim before 4.90.1. By sending a handcrafted message, a buffer overflow may happen. This can be used to execute code remotely.
CVE-2019-8912 4 Canonical, Linux, Opensuse and 1 more 4 Ubuntu Linux, Linux Kernel, Leap and 1 more 2021-06-02 7.2 HIGH 7.8 HIGH
In the Linux kernel through 4.20.11, af_alg_release() in crypto/af_alg.c neglects to set a NULL value for a certain structure member, which leads to a use-after-free in sockfs_setattr.
CVE-2019-8980 4 Canonical, Debian, Linux and 1 more 4 Ubuntu Linux, Debian Linux, Linux Kernel and 1 more 2021-06-02 7.8 HIGH 7.5 HIGH
A memory leak in the kernel_read_file function in fs/exec.c in the Linux kernel through 4.20.11 allows attackers to cause a denial of service (memory consumption) by triggering vfs_read failures.
CVE-2019-9003 4 Canonical, Linux, Netapp and 1 more 8 Ubuntu Linux, Linux Kernel, Cn1610 and 5 more 2021-06-02 7.8 HIGH 7.5 HIGH
In the Linux kernel before 4.20.5, attackers can trigger a drivers/char/ipmi/ipmi_msghandler.c use-after-free and OOPS by arranging for certain simultaneous execution of the code, as demonstrated by a "service ipmievd restart" loop.
CVE-2018-20784 3 Canonical, Linux, Redhat 4 Ubuntu Linux, Linux Kernel, Enterprise Linux and 1 more 2021-06-02 7.5 HIGH 9.8 CRITICAL
In the Linux kernel before 4.20.2, kernel/sched/fair.c mishandles leaf cfs_rq's, which allows attackers to cause a denial of service (infinite loop in update_blocked_averages) or possibly have unspecified other impact by inducing a high load.
CVE-2019-15538 6 Canonical, Debian, Fedoraproject and 3 more 28 Ubuntu Linux, Debian Linux, Fedora and 25 more 2021-06-02 7.8 HIGH 7.5 HIGH
An issue was discovered in xfs_setattr_nonsize in fs/xfs/xfs_iops.c in the Linux kernel through 5.2.9. XFS partially wedges when a chgrp fails on account of being out of disk quota. xfs_setattr_nonsize is failing to unlock the ILOCK after the xfs_qm_vop_chown_reserve call fails. This is primarily a local DoS attack vector, but it might result as well in remote DoS if the XFS filesystem is exported for instance via NFS.
CVE-2017-8831 3 Canonical, Debian, Linux 3 Ubuntu Linux, Debian Linux, Linux Kernel 2021-06-01 6.9 MEDIUM 6.4 MEDIUM
The saa7164_bus_get function in drivers/media/pci/saa7164/saa7164-bus.c in the Linux kernel through 4.11.5 allows local users to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact by changing a certain sequence-number value, aka a "double fetch" vulnerability.
CVE-2019-14907 5 Canonical, Fedoraproject, Redhat and 2 more 9 Ubuntu Linux, Fedora, Enterprise Linux and 6 more 2021-05-29 2.6 LOW 6.5 MEDIUM
All samba versions 4.9.x before 4.9.18, 4.10.x before 4.10.12 and 4.11.x before 4.11.5 have an issue where if it is set with "log level = 3" (or above) then the string obtained from the client, after a failed character conversion, is printed. Such strings can be provided during the NTLMSSP authentication exchange. In the Samba AD DC in particular, this may cause a long-lived process(such as the RPC server) to terminate. (In the file server case, the most likely target, smbd, operates as process-per-client and so a crash there is harmless).
CVE-2019-1000018 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2021-05-28 4.6 MEDIUM 7.8 HIGH
rssh version 2.3.4 contains a CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') vulnerability in allowscp permission that can result in Local command execution. This attack appear to be exploitable via An authorized SSH user with the allowscp permission.
