A vulnerability was found in linux kernel, where an information leak occurs via ext4_extent_header to userspace.

A vulnerability was found in linux kernel, where an information leak occurs via ext4_extent_header to userspace.

Affected: openEuler:20.03-LTS-SP1: kernel, openEuler:20.03-LTS-SP2: kernel

The Linux Kernel, the operating system core itself. Security Fix(es): A NULL pointer dereference flaw was found in the Linux kernel’s IEEE 802.15.4 wireless networking subsystem in the way the user closes the LR-WPAN connection. This flaw allows a local user to crash the system. The highest threat from this vulnerability is to system availability.(CVE-2021-3659) arch/powerpc/kvm/book3s_rtas.c in the Linux kernel through 5.13.5 on the powerpc platform allows KVM guest OS users to cause host OS memory corruption via rtas_args.nargs, aka CID-f62f3c20647e.(CVE-2021-37576) A vulnerability was found in the Linux kernel in versions before v5.14-rc1. Missing size validations on inbound SCTP packets may allow the kernel to read uninitialized memory.(CVE-2021-3655).

No description is available for this CVE.(CVE-2022-0850).

An issue was discovered in shadow 4.5. newgidmap (in shadow-utils) is setuid and allows an unprivileged user to be placed in a user namespace where setgroups(2) is permitted. This allows an attacker to remove themselves from a supplementary group, which may allow access to certain filesystem paths if the administrator has used "group blacklisting" (e.g., chmod g-rwx) to restrict access to paths. This flaw effectively reverts a security feature in the kernel (in particular, the /proc/self/setgroups knob) to prevent this sort of privilege escalation. GnuPG 2.2.4 and 2.2.5 does not enforce a configuration in which key certification requires an offline master Certify key, which results in apparently valid certifications that occurred only with access to a signing subkey. remember_Ktype in cplus-dem.c in GNU libiberty, as distributed in GNU Binutils 2.30, allows attackers to trigger excessive memory consumption (aka OOM). This can occur during execution of cxxfilt. binutils version 2.32 and earlier contains a Integer Overflow vulnerability in objdump, bfd_get_dynamic_reloc_upper_bound,bfd_canonicalize_dynamic_reloc that can result in Integer overflow trigger heap overflow. Successful exploitation allows execution of arbitrary code.. This attack appear to be exploitable via Local. This vulnerability appears to have been fixed in after commit 3a551c7a1b80fca579461774860574eabfd7f18f. libseccomp before 2.4.0 did not correctly generate 64-bit syscall argument comparisons using the ar…

Ein entfernter, anonymer, authentisierter oder lokaler Angreifer kann mehrere Schwachstellen in IBM Spectrum Protect ausnutzen, um einen Denial-of-Service-Zustand herbeizuführen, Sicherheitsmaßnahmen zu umgehen, vertrauliche Informationen offenzulegen, beliebigen Code auszuführen, seine Rechte zu erweitern oder beliebigen Code mit Root-Rechten auszuführen.
