USN-5389-1: Libcroco vulnerabilities

Read Time:36 Second

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)

USN-5390-1: Linux kernel vulnerabilities

Read Time:36 Second

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)

USN-5388-2: OpenJDK vulnerabilities

Read Time:53 Second

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. (CVE-2022-21476)

It was discovered that OpenJDK incorrectly parsed certain URI strings. An
attacker could possibly use this issue to make applications accept
invalid of malformed URI strings. (CVE-2022-21496)
