A vulnerability was found in libguestfs. This issue occurs while calculating the greatest possible number of matching keys in the get_keys() function. This flaw leads to a denial of service, either by mistake or malicious actor.
Security vulnerabilities in HPE IceWall SSO 10.0 certd could be exploited remotely to allow SQL injection or unauthorized data injection. HPE has provided the following updated modules to resolve these vulnerabilities. HPE IceWall SSO version 10.0 certd library Patch 9 for RHEL and HPE IceWall SSO version 10.0 certd library Patch 9 for HP-UX.
A privilege escalation flaw was found in the token exchange feature of keycloak. Missing authorization allows a client application holding a valid access token to exchange tokens for any target client by passing the client_id of the target. This could allow a client to gain unauthorized access to additional services.
A insecure configuration for certificate verification (http.verify_mode = OpenSSL::SSL::VERIFY_NONE) may lead to verification bypass in Red Hat CloudForms 5.x.
A crafted 16-bit grayscale PNG image may lead to a out-of-bounds write in the heap area. An attacker may take advantage of that to cause heap data corruption or eventually arbitrary code execution and circumvent secure boot protections. This issue has a high complexity to be exploited as an attacker needs to perform some triage over the heap layout to achieve signifcant results, also the values written into the memory are repeated three times in a row making difficult to produce valid payloads. This flaw affects grub2 versions prior grub-2.12.
A heap out-of-bounds write may heppen during the handling of Huffman tables in the PNG reader. This may lead to data corruption in the heap space. Confidentiality, Integrity and Availablity impact may be considered Low as it's very complex to an attacker control the encoding and positioning of corrupted Huffman entries to achieve results such as arbitrary code execution and/or secure boot circumvention. This flaw affects grub2 versions prior grub-2.12.
A crafted JPEG image may lead the JPEG reader to underflow its data pointer, allowing user-controlled data to be written in heap. To a successful to be performed the attacker needs to perform some triage over the heap layout and craft an image with a malicious format and payload. This vulnerability can lead to data corruption and eventual code execution or secure boot circumvention. This flaw affects grub2 versions prior grub-2.12.
The simplepush server iterates through the application installations and pushes a notification to the server provided by deviceToken. But this is user controlled. If a bogus applications is registered with bad deviceTokens, one can generate endless exceptions when those endpoints can't be reached or can slow the server down by purposefully wasting it's time with slow endpoints. Similarly, one can provide whatever HTTP end point they want. This turns the server into a DDOS vector or an anonymizer for the posting of malware and so on.
Multiple persistent cross-site scripting (XSS) flaws were found in the way Aerogear handled certain user-supplied content. A remote attacker could use these flaws to compromise the application with specially crafted input.
