Astra Linux – Vulnerability in hiredis

Hiredis is a minimalistic C client library for the Redis database. In affected versions, Hiredis can be vulnerable to integer overflow if maliciously crafted or corrupted RESP mult-bulk protocol data is provided. When parsing mult-bulk array-like replies, Hiredis fails to check whether count...

Astra Linux – Vulnerability in Linux 5.10, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: icmp6: Fixed the null-ptr-deref of ip6nullentry-rt6iidev in icmp6dev. With some IPv6 Ext Hdr RPL, SRv6, etc., we can send a packet that has the link-local address as src and dst IP, and it will be forwarded to an external IP in t...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net, neigh: Fixed the null-ptr-deref in neightableclear. When the IPv6 module is initialized, an error occurs in the middle. This results in a kernel panic with the following error message: KASAN: Nullptrderef in range...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: net: stmmac – ensure that ptprate is not set to 0 before configuring EST. If the value of ptprate, which was previously recorded in the driver, happens to be 0, this invalid value will be propagated up to the EST configuration,...

Astra Linux – Vulnerability in edk2

EDK2’s Network Package is vulnerable to an infinite loop vulnerability when parsing a PadN option in the Destination Options header of IPv6. This vulnerability can be exploited by an attacker to gain unauthorized access and potentially lead to a loss of availability...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.2, an unvalidated authlength field read from the network triggered a WINPRASSERT failure in rtsreadauthverifiernochecks, causing any FreeRDP client connecting through a malicious RDP Gateway to crash with...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.0, a underflow of a sizet variable in the IMA-ADPCM and MS-ADPCM audio decoders led to a heap-buffer-overflow issue through the RDPSND audio channel. In libfreerdp/codec/dsp.c, the IMA-ADPCM and MS-ADPCM decode...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: SCTP: Added mutual exclusion in procsctpdoudpport. We must serialize calls to sctpudpsockstop and sctpudpsockstart, or risk a crash, as syzbot reported: Oops: General protection fault, likely due to a non-canonical address...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: nvmet-tcp: Do not restore null skstatechange. queue-statechange is set as part of nvmettcpsetqueuesock, but if the TCP connection is not established when nvmettcpsetqueuesock is called, then queue-statechange is not set, and...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, xfAppUpdateWindowFromSurface reused a cached XImage, where the data pointer referred to an RDPGFX surface buffer that had been freed. This was because gdiDeleteSurface freed surface-data without invalidating...

Astra Linux – Vulnerability in Firefox

Even when an iframe was sandboxed with allow-top-navigation-by-user-activation, if it received a redirect header to an external protocol, the browser would process the redirect and prompt the user appropriately. This vulnerability affects Firefox versions earlier than 102...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: SCTP: Fixed a memory leak in sctpstreamoutqmigrate. When sctpstreamoutqmigrate is called to release resources related to streamouts, the memory pointed to by priohead in the streamout context is not released properly. The details...

Astra Linux – Vulnerability in libx11

The LookupCol.c file in X.Org X, as well as versions of X11 such as X11R7.7 and libX11 before version 1.7.1, may allow remote attackers to execute arbitrary code. The libX11 XLookupColor function, intended for server-side color lookups, contains a flaw that allows a client to send color-name...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: cifs: Fixed an integer overflow issue while processing the closetimeo mount option. The user-provided closetimeo mount parameter, of type u32, is intended to have an upper limit. However, before this limit is validated, the value...

Astra Linux – Vulnerability in unbound

The DNS protocol in RFC 1035 and its updates allows remote attackers to cause a denial of service resource consumption by arranging for DNS queries to be accumulated over seconds. As a result, responses are sent in a pulsing burst, which can be considered traffic amplification in some cases. This...
