redhat-certification: resource consumption in DocumentBase:loadFiltered

An uncontrolled resource consumption flaw has been discovered in redhat-certification in the way documents are loaded. A remote attacker may provide an existing but invalid XML file which would be opened and never closed, possibly producing a Denial of Service.

redhat-certification: directory listing in /rhcert-transfer

It was discovered that redhat-certification 7 is not properly configured and it lists all files and directories in the /var/www/rhcert/store/transfer directory, through the /rhcert-transfer URL. An unauthorized attacker may use this flaw to gather sensible information.

wildfly-core: Path traversal can allow the extraction of .war archives to write arbitrary files (Zip Slip)

WildFly Core before version 6.0.0.Alpha3 does not properly validate file paths in .war archives, allowing for the extraction of crafted .war archives to overwrite arbitrary files. This is an instance of the 'Zip Slip' vulnerability.

ceph: ceph-mon does not perform authorization on OSD pool ops

A flaw was found in the way ceph mon handles user requests. Any authenticated ceph user having read access to ceph can delete, create ceph storage pools and corrupt snapshot images. Ceph branches master, mimic, luminous and jewel are believed to be affected.

perl-Archive-Zip: Directory traversal in Archive::Zip

perl-archive-zip is vulnerable to a directory traversal in Archive::Zip. It was found that the Archive::Zip module did not properly sanitize paths while extracting zip files. An attacker able to provide a specially crafted archive for processing could use this flaw to write or overwrite arbitrary files in the context of the perl interpreter.

git-annex is vulnerable to an Information Exposure when decrypting files. A malicious server for a special remote could trick git-annex into decrypting a file that was encrypted to the user's gpg key. This attack could be used to expose encrypted data that was never stored in git-annex

samba: Insufficient input validation in libsmbclient

A heap-buffer overflow was found in the way samba clients processed extra long filename in a directory listing. A malicious samba server could use this flaw to cause arbitrary code execution on a samba client. Samba versions before 4.6.16, 4.7.9 and 4.8.4 are vulnerable.

git-annex is vulnerable to a private data exposure and exfiltration attack. It could expose the content of files located outside the git-annex repository, or content from a private web server on localhost or the LAN.

podman: Containers run as non-root users do not drop capabilities

It has been discovered that podman before version 0.6.1 does not drop capabilities when executing a container as a non-root user. This results in unnecessary privileges being granted to the container.

ansible: Failed tasks do not honour no_log option allowing for secrets to be disclosed in logs

Ansible 2.5 prior to 2.5.5, and 2.4 prior to 2.4.5, do not honor the no_log task flag for failed tasks. When the no_log flag has been used to protect sensitive data passed to a task from being logged, and that task does not run successfully, Ansible will expose sensitive data in log files and on the terminal of the user running Ansible.

cloudforms: stored cross-site scripting in Name field

cloudforms version, cloudforms 5.8 and cloudforms 5.9, is vulnerable to a cross-site-scripting. A flaw was found in CloudForms's v2v infrastructure mapping delete feature. A stored cross-site scripting due to improper sanitization of user input in Name field.

kernel: kvm: guest userspace to guest kernel write

A flaw was found in the way Linux kernel KVM hypervisor before 4.18 emulated instructions such as sgdt/sidt/fxsave/fxrstor. It did not check current privilege(CPL) level while emulating unprivileged instructions. An unprivileged guest user/process could use this flaw to potentially escalate privileges inside guest.

sssd: information leak from the sssd-sudo responder

The UNIX pipe which sudo uses to contact SSSD and read the available sudo rules from SSSD has too wide permissions, which means that anyone who can send a message using the same raw protocol that sudo and SSSD use can read the sudo rules available for any user. This affects versions of SSSD before 1.16.3.

PowerDNS Authoritative Server 3.3.0 up to 4.1.4 excluding 4.1.5 and 4.0.6, and PowerDNS Recursor 3.2 up to 4.1.4 excluding 4.1.5 and 4.0.9, are vulnerable to a memory leak while parsing malformed records that can lead to remote denial of service.

389-ds-base: race condition on reference counter leads to DoS using persistent search

389-ds-base before versions 1.4.0.10, 1.3.8.3 is vulnerable to a race condition in the way 389-ds-base handles persistent search, resulting in a crash if the server is under load. An anonymous attacker could use this flaw to trigger a denial of service.

prosody before versions 0.10.2, 0.9.14 is vulnerable to an Authentication Bypass. Prosody did not verify that the virtual host associated with a user session remained the same across stream restarts. A user may authenticate to XMPP host A and migrate their authenticated session to XMPP host B of the same Prosody instance.

gnutls: "Just in Time" PRIME + PROBE cache-based side channel attack can lead to plaintext recovery

A cache-based side channel in GnuTLS implementation that leads to plain text recovery in cross-VM attack setting was found. An attacker could use a combination of "Just in Time" Prime+probe attack in combination with Lucky-13 attack to recover plain text using crafted packets.

gnutls: HMAC-SHA-384 vulnerable to Lucky thirteen attack due to use of wrong constant

It was found that the GnuTLS implementation of HMAC-SHA-384 was vulnerable to a Lucky thirteen style attack. Remote attackers could use this flaw to conduct distinguishing attacks and plain text recovery attacks via statistical analysis of timing data using crafted packets.

gnutls: HMAC-SHA-256 vulnerable to Lucky thirteen attack due to not enough dummy function calls

It was found that the GnuTLS implementation of HMAC-SHA-256 was vulnerable to a Lucky thirteen style attack. Remote attackers could use this flaw to conduct distinguishing attacks and plaintext-recovery attacks via statistical analysis of timing data using crafted packets.

source-to-image: Builder images with assembler-user LABEL set to root allows attackers to execute arbitrary code

source-to-image component of Openshift Container Platform before versions atomic-openshift 3.7.53, atomic-openshift 3.9.31 is vulnerable to a privilege escalation which allows the assemble script to run as the root user in a non-privileged container. An attacker can use this flaw to open network connections, and possibly other actions, on the host which are normally only available to a root user.
