Time-of-check Time-of-use (TOCTOU) Race Condition
Overview Affected versions of this package are vulnerable to Time-of-check Time-of-use TOCTOU Race Condition in the daemon file handling. An attacker can create or overwrite arbitrary files by replacing parent directory components with symbolic links during the window between validation and use...
Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15
The Linux kernel allows user-space processes to enable mitigations by calling prctl with PRSETSPECULATIONCTRL, which disables the speculation feature, as well as through the use of seccomp. We noticed that on virtual machines of at least one major cloud provider, the kernel still left the victim...
Astra Linux – Vulnerability in Linux
Aliases in the branch predictor may cause some AMD processors to predict the wrong branch type, potentially leading to information disclosure...
Astra Linux – Vulnerability in Linux 5.10, Linux
Mis-trained branch predictions for return instructions may allow arbitrary speculative code execution under certain microarchitecture-dependent conditions...
Astra Linux – Vulnerability in Linux 5.10, Linux
A known cache speculation vulnerability, known as Branch History Injection BHI or Spectre-BHB, reappears in the new hw AmpereOne. Spectre-BHB is similar to Spectre v2, except that malicious code uses the shared branch history stored in the CPU Branch History Buffer, or BHB to influence mispredict...
Astra Linux – Vulnerability in Linux, Linux 5.10
The non-transparent sharing of the branch predictor within the context of some Intel processors may allow an authorized user to potentially enable information disclosure through local access...
Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1
In the Linux kernel, the following vulnerability has been resolved: x86/hyperv: Disabling IBT when the hypercall page lacks the ENDBR instruction. On hardware that supports Indirect Branch Tracking IBT, Hyper-V VMs with ConfigVersion 9.3 or later support IBT in the guest. However, current version...
Astra Linux – Vulnerability in Linux
JIT compilers in the Linux kernel from version 5.11.12 have incorrect calculations of branch displacements, allowing them to execute arbitrary code within the kernel context. This issue affects the files arch/x86/net/bpfjitcomp.c and arch/x86/net/bpfjitcomp32.c...
Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1
In the Linux kernel, the following vulnerabilities have been resolved: KVM: x86/pmu: Disabled support for adaptive PEBS. Support for virtualizing adaptive PEBS has been discontinued. This is because KVM’s implementation is architecturally broken without an obvious or easy way to address this issu...
Astra Linux – Vulnerability in symfony
Symfony is a PHP framework for web and console applications, along with a set of reusable PHP components. The Symfony HTTP cache system functions as a reverse proxy: it caches entire responses including headers and returns them to clients. In a recent change to the AbstractSessionListener,...
Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1
In the Linux kernel, the following vulnerability has been resolved: perf/x86/lbr: Filtering vsyscall addresses We found that a panic can occur when a vsyscall is executed while LBR sampling is active. If the vsyscall is interrupted via NMI for perf sampling purposes, the following call sequence m...
Astra Linux – Vulnerability in Linux 5.10
There is a vulnerability in the Linux Kernel within the KVM framework: nVMX, which allows for speculative execution attacks. L2 can execute Spectre v2 attacks on L1, as L1 believes it does not need retpolines or IBPB after executing L2, due to KVM L0 indicating support for eIBRS to L1. An attacke...
Astra Linux – Vulnerability in Linux, Linux 5.10
Certain Arm Cortex and Neoverse processors, as of 2022-03-08, do not properly prevent cache speculation, also known as Spectre-BHB. Attackers can exploit the shared branch history in the Branch History Buffer BHB to influence mispredicted branches. As a result, cache allocation may allow attacker...
Astra Linux – Vulnerability in Linux
In kernel/bpf/verifier.c in the Linux kernel before version 5.12.13, a branch prediction can be mispredicted e.g., due to type confusion, allowing a non-privileged BPF program to access arbitrary memory locations through a side-channel attack, known as CID-9183671af6db...
Astra Linux – Vulnerability in Linux 5.10, Linux
The current implementation of the prctl syscall does not issue an IBPB immediately during the syscall. The ibprctlset function updates the Thread Information Flags TIFs for the task and updates the SPECCTRL MSR in the function speculationctrlupdate, but the IBPB is only issued at the next schedul...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: s390/entry: Scrub r12 register on kernel entry Before the commit of f33f2d4c7c80 “s390/bp: remove TIFISOLATEBP”, all entry handlers loaded r12 with the current task pointer lg %r12, LCCURRENT for use by the BPENTER/BPEXIT macros...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerabilities have been resolved: Wifi: mac80211: Fixed an underflow in staticbranchdec for aqldisable. syzbot reported an underflow in staticbranchdec in aqlenablewrite. 0 The issue arises because aqlenablewrite does not serialize concurrent write operations ...
Astra Linux – Vulnerability in symfony
Symfony is a PHP framework for web and console applications, along with a set of reusable PHP components. The ability to enumerate users was possible without requiring relevant permissions, as the handling differed depending on whether the user existed or not when attempting to use the “switch...
Astra Linux – Vulnerability in Linux, Linux 5.10
The non-transparent sharing of branch predictor selectors between contexts in some Intel processors may allow an authorized user to potentially enable information disclosure through local access...
