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-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-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-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-2017-9788 6 Apache, Apple, Debian and 3 more 16 Http Server, Mac Os X, Debian Linux and 13 more 2021-06-06 6.4 MEDIUM 9.1 CRITICAL
In Apache httpd before 2.2.34 and 2.4.x before 2.4.27, the value placeholder in [Proxy-]Authorization headers of type 'Digest' was not initialized or reset before or between successive key=value assignments by mod_auth_digest. Providing an initial key with no '=' assignment could reflect the stale value of uninitialized pool memory used by the prior request, leading to leakage of potentially confidential information, and a segfault in other cases resulting in denial of service.
CVE-2017-3167 6 Apache, Apple, Debian and 3 more 15 Http Server, Mac Os X, Debian Linux and 12 more 2021-06-06 7.5 HIGH 9.8 CRITICAL
In Apache httpd 2.2.x before 2.2.33 and 2.4.x before 2.4.26, use of the ap_get_basic_auth_pw() by third-party modules outside of the authentication phase may lead to authentication requirements being bypassed.
CVE-2018-1333 4 Apache, Canonical, Netapp and 1 more 6 Http Server, Ubuntu Linux, Cloud Backup and 3 more 2021-06-06 5.0 MEDIUM 7.5 HIGH
By specially crafting HTTP/2 requests, workers would be allocated 60 seconds longer than necessary, leading to worker exhaustion and a denial of service. Fixed in Apache HTTP Server 2.4.34 (Affected 2.4.18-2.4.30,2.4.33).
CVE-2018-1301 5 Apache, Canonical, Debian and 2 more 8 Http Server, Ubuntu Linux, Debian Linux and 5 more 2021-06-06 4.3 MEDIUM 5.9 MEDIUM
A specially crafted request could have crashed the Apache HTTP Server prior to version 2.4.30, due to an out of bound access after a size limit is reached by reading the HTTP header. This vulnerability is considered very hard if not impossible to trigger in non-debug mode (both log and build level), so it is classified as low risk for common server usage.
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-2021-3393 2 Postgresql, Redhat 3 Postgresql, Enterprise Linux, Software Collections 2021-06-04 3.5 LOW 4.3 MEDIUM
An information leak was discovered in postgresql in versions before 13.2, before 12.6 and before 11.11. A user having UPDATE permission but not SELECT permission to a particular column could craft queries which, under some circumstances, might disclose values from that column in error messages. An attacker could use this flaw to obtain information stored in a column they are allowed to write but not read.
CVE-2021-20297 3 Fedoraproject, Gnome, Redhat 4 Fedora, Networkmanager, Enterprise Linux and 1 more 2021-06-03 2.1 LOW 5.5 MEDIUM
A flaw was found in NetworkManager in versions before 1.30.0. Setting match.path and activating a profile crashes NetworkManager. The highest threat from this vulnerability is to system availability.
CVE-2021-3505 3 Fedoraproject, Libtpms Project, Redhat 3 Fedora, Libtpms, Enterprise Linux 2021-06-03 2.1 LOW 5.5 MEDIUM
A flaw was found in libtpms in versions before 0.8.0. The TPM 2 implementation returns 2048 bit keys with ~1984 bit strength due to a bug in the TCG specification. The bug is in the key creation algorithm in RsaAdjustPrimeCandidate(), which is called before the prime number check. The highest threat from this vulnerability is to data confidentiality.
CVE-2021-20486 3 Ibm, Linux, Redhat 3 Cloud Pak For Data, Linux Kernel, Enterprise Linux 2021-06-02 4.0 MEDIUM 6.5 MEDIUM
IBM Cloud Pak for Data 3.0 could allow an authenticated user to obtain sensitive information when installed with additional plugins. IBM X-Force ID: 197668.
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-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-2021-20291 3 Fedoraproject, Redhat, Storage Project 4 Fedora, Enterprise Linux, Openshift Container Platform and 1 more 2021-06-02 7.1 HIGH 6.5 MEDIUM
A deadlock vulnerability was found in 'github.com/containers/storage' in versions before 1.28.1. When a container image is processed, each layer is unpacked using `tar`. If one of those layers is not a valid `tar` archive this causes an error leading to an unexpected situation where the code indefinitely waits for the tar unpacked stream, which never finishes. An attacker could use this vulnerability to craft a malicious image, which when downloaded and stored by an application using containers/storage, would then cause a deadlock leading to a Denial of Service (DoS).
CVE-2021-20231 4 Fedoraproject, Gnu, Netapp and 1 more 5 Fedora, Gnutls, Active Iq Unified Manager and 2 more 2021-06-01 7.5 HIGH 9.8 CRITICAL
A flaw was found in gnutls. A use after free issue in client sending key_share extension may lead to memory corruption and other consequences.
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-2021-3411 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2021-05-21 4.6 MEDIUM 6.7 MEDIUM
A flaw was found in the Linux kernel in versions prior to 5.10. A violation of memory access was found while detecting a padding of int3 in the linking state. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2018-14718 5 Debian, Fasterxml, Netapp and 2 more 26 Debian Linux, Jackson-databind, Oncommand Workflow Automation and 23 more 2021-05-21 7.5 HIGH 9.8 CRITICAL
FasterXML jackson-databind 2.x before 2.9.7 might allow remote attackers to execute arbitrary code by leveraging failure to block the slf4j-ext class from polymorphic deserialization.
