Astra Linux – Vulnerability in libvirt

A flaw was discovered in the RPC library APIs of libvirt. The RPC server deserialization code allocates memory for arrays before performing the negative length check by the C API entry points. Passing a negative length to the gnew0 function results in a crash because the negative length is treate...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

Transmitted requests in Xen’s virtual network protocol can consist of multiple parts. Although none of them are actually useful, except for the initial part, any of these parts can be of zero length, meaning they carry no data at all. In addition to the certain initial portion of the data to be...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerability has been resolved: afs: Increase the buffer size in afsupdatevolumestatus. The maximum length of the volume-vid value is 20 characters. Therefore, increase the size of idbuf to 24 to avoid overflow. Found by the Linux Verification Center...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: erspan: Initialize optionslen before referencing options. The struct iptunnelinfo structure has a flexible array member named options, which is protected by the countedbyoptionslen attribute. The compiler uses this information to...

In the Linux kernel, the following vulnerabilities have been resolved: netfilter: nfconntrackh323: Added protection against bmp length being out of range. The UBSAN load reports an exception due to bitwise shifts that are out of bounds for their data type. vmlinux getbitmapb=75 + 712 vmlinux...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fixed the issue of loading the RxGK token to check bounds. The rxrpcpreparsexdryfsrxgk function reads the raw key length and ticket length from the XDR token as u32 values. It then rounds up each value by 4 before using th...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: Wifi: iwlwifi: mvm – fixed a potential out-of-bounds read in iwlmvmndmatchinfohandler The memcpy function assumes that the dynamic array notif-matches is at least as large as the number of bytes to be copied. Otherwise,...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net: Do not write to msggetinq in the callee. A fix for NULL pointer dereferencing issues. msggetinq is an input field from the caller to the callee. Do not set it in the callee, as the caller may not clear it during struct reuse...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: hwmon: tps53679 Fixed array access with zero-length block reads. i2csmbusreadblockdata can return 0, indicating a zero-length read. When this occurs, tps53679identifychip accesses bufret - 1, which is actually buf-1. This mean...

Astra Linux - уязвимость в u-boot

There exists an unchecked length field in UBoot. The U-Boot DFU implementation does not bind the length field in USB DFU download setup packets, and it does not verify that the transfer direction corresponds to the specified command. Consequently, if a physical attacker creates a USB DFU download...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: NFSD: prevented underflow in nfssvcdecodewriteargs Smatch reported the issue as follows: fs/nfsd/nfsxdr.c:341 nfssvcDecodeWriteArgs Warning: no lower bound on ‘args-len’ The type of the variable has been changed to unsigned to...

Astra Linux – Vulnerability in liblivemedia

In Live555 0.95, there is a buffer overflow due to a large integer in the Content-Length HTTP header. This occurs because the handleRequestBytes function uses a memmove operation without proper bounds...

Astra Linux – Vulnerability in node-moment

moment is a JavaScript date library for parsing, validating, manipulating, and formatting dates. Versions of moment that were affected use an inefficient parsing algorithm. Specifically, the string-to-date parsing method used by moment more precisely, the rfc2822 parsing method, which is used by...

Astra Linux – Vulnerability in Netty

Netty 4.1.43.Final allows HTTP Request Smuggling because it mishandles Transfer-Encoding whitespace such as a spaceTransfer-Encoding:chunked line and a later Content-Length header. This issue exists due to an incomplete fix for CVE-2019-16869...

A issue was discovered in Das U-Boot during the period from 2019.07. There is an unbounded memcpy operation with an unvalidated length at nfsreadlinkreply, located in the “if” block, after calculating the new path length...

Astra Linux – Vulnerability in Vino

A issue was discovered in LibVNCServer through version 0.9.11. The function rfbProcessClientNormalMessage in rfbserver.c does not sanitize the msg.cct.length variable, allowing access to uninitialized and potentially sensitive data, or possibly causing unspecified other impacts e.g., integer...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net: xilinx: axienet: Fixed BQL accounting for multi-BD TX packets. When a TX packet spans multiple buffer descriptors scatter-gather, axienetfreetxchain sums the actual length of each BD from the descriptor status into an...
