In the Linux kernel, the following vulnerabilities have been resolved: ipv4, ipv6: Fixed the handling of transhdrlen in ip,6appenddata. Including transhdrlen in the packet length is a problem when the packet is partially filled e.g., a sendMSGMORE operation occurred previously when appending to a...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: smb: server: The use of smbdirectsocket.sendio.bcredits has been addressed. It turns out that our code will corrupt the stream of reassabled data transfer messages when we trigger an immediate empty send. To fix this issue, we wi...

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 – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/xe/xepagefault: Writers to read-only Virtual Memory Addresses are now disallowed. The page fault handler should reject write/atomic accesses to read-only Virtual Memory Addresses. Add code to handle this in xepagefaultservice...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: rxrpc: A integer overflow has been fixed in rxgkverifyresponse. In rxgkverifyresponse, there is a potential integer overflow due to rounding the tokenlen value up before checking it. This allows the length check to be bypassed...

Astra Linux – Vulnerability in pcre2

A out-of-bounds read vulnerability was discovered in the PCRE2 library, specifically in the getrecursedatalength function of the pcre2jitcompile.c file. This issue affects recursions in JIT-compiled regular expressions due to duplicate data transfers...

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

In the Linux kernel, the following vulnerability has been resolved: fs: hfsplus: removing WARNON from hfspluscatread,writeinode. The syzbot tool encounters WARNON in hfspluscatread,writeinode, where a crafted filesystem image may contain invalid lengths. These conditions do not constitute kernel...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net: netlink: afnetlink: Added a check on the len parameter to prevent empty skb objects. This prevents a division error in the netemenqueue function, which occurs when skb-len=0 and skb-datalen=0 during the randomized corruption...

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

In the Linux kernel, the following vulnerability has been resolved: Netfilter: nftables: exthdr: fixed a 4-byte OOB write issue. If priv-len is a multiple of 4, then dstlen / 4 can write beyond the destination array, leading to stack corruption. This fix is necessary to handle the remainder of th...

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

In the Linux kernel, the following vulnerability has been resolved: Ring-buffer: Do not attempt to read beyond the “commit” boundary. When iterating over the ring buffer while the ring buffer is active, the writer can corrupt the reader’s data. There are mechanisms to detect and handle this issue...

Astra Linux – Vulnerability in Apache2

Apache HTTP Server versions 2.4.41 to 2.4.46 with modproxyhttp can become unstable when processing specially crafted requests that use both Content-Length and Transfer-Encoding headers. This can lead to a denial of service...

Astra Linux – Vulnerability in Waitress

Waitress version 1.3.1 allows for the smuggling of requests by sending the Content-Length header twice. Waitress would fold the two Content-Length headers together, and since it cannot convert the now comma-separated values into integers, it internally sets the Content-Length to 0. If two...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: virt: tdx-guest: Fixed the handling of the “quote” buffer length controlled by the host. The host-controlled value quotebuf-outlen is validated to determine how many bytes of the quote are copied to the guest userspace. In TDX...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: Wifi: mt76: mt7925: Fixed possible out-of-band OOB access in mt7925macwritetxwi80211. Check the frame length before accessing the mgmt fields in mt7925macwritetxwi80211 in order to avoid possible OOB access...

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

In the Linux kernel, the following vulnerabilities have been resolved: netlink: Do not hard code the device address length in fdb dumps. syzbot reports that some netdev devices do not have a six-byte address. Replace ETHALEN with dev-addrlen. 1 In cases where dev-addrlen = 4 BUG: KMSAN:...

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...
