USN-5389-1: Libcroco vulnerabilities It was discovered that Libcroco was incorrectly accessing data structures when reading bytes from memory, which could cause a heap buffer overflow. An attacker could possibly use this issue to cause a denial of service. (CVE-2017-7960) It was discovered that Libcroco was incorrectly handling invalid UTF-8 values when processing CSS files. An attacker could possibly use this issue to cause a denial of service. (CVE-2017-8834, CVE-2017-8871) It was discovered that Libcroco was incorrectly implementing recursion in one of its parsing functions, which could cause an infinite recursion loop and a stack overflow due to stack consumption. An attacker could possibly use this issue to cause a denial of service. (CVE-2020-12825) Source: USN-5389-1: Libcroco vulnerabilities

USN-5390-1: Linux kernel vulnerabilities David Bouman discovered that the netfilter subsystem in the Linux kernel did not properly validate passed user register indices. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. (CVE-2022-1015) David Bouman discovered that the netfilter subsystem in the Linux kernel did not initialize memory in some situations. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2022-1016) It was discovered that the ST21NFCA NFC driver in the Linux kernel did not properly validate the size of certain data in EVT_TRANSACTION events. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-26490) Source: USN-5390-1: Linux kernel vulnerabilities

USN-5388-2: OpenJDK vulnerabilities It was discovered that OpenJDK incorrectly verified ECDSA signatures. An attacker could use this issue to bypass the signature verification process. (CVE-2022-21449) It was discovered that OpenJDK incorrectly limited memory when compiling a specially crafted XPath expression. An attacker could possibly use this issue to cause a denial of service. (CVE-2022-21426) It was discovered that OpenJDK incorrectly handled converting certain object arguments into their textual representations. An attacker could possibly use this issue to cause a denial of service. (CVE-2022-21434) It was discovered that OpenJDK incorrectly validated the encoded length of certain object identifiers. An attacker could possibly use this issue to cause a denial of service. (CVE-2022-21443) It was discovered that OpenJDK incorrectly validated certain paths. An attacker could possibly use this issue to bypass the secure validation feature and expose sensitive information in XML files. [ more… ]
