There is an integer underflow vulnerability in the OLE Document DIFAT Parser functionality of catdoc 0.95. A specially crafted, malformed file can lead to heap-based memory corruption. An attacker can provide a malicious file to exploit this vulnerability...

Astra Linux – Vulnerability in xrdp

XRDPT is an open-source remote desktop protocol RDP server. In affected versions, an integer underflow leading to a heap overflow in the SESMAN server allows any unauthenticated attacker who can access the SESMAN server locally to execute code as root. This vulnerability has been patched in versi...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Clear the optc underflow before turning off the ODM clock. Why After the ODM clock is turned off, the optc underflow bit remains there indefinitely, and clearing it doesn’t work. We need to clear that bit before...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: netfilter: nfconntrackh323 – check for zero length in DecodeQ931. In DecodeQ931, the UserUserIE code path reads a 16-bit length from the packet, then decrements it by 1 to skip the protocol discriminator byte before passing it to...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: drm/i915/gt: Fixed a refcount underflow in intelengineparkheartbeat. A use-after-free or refcount underflow may occur when the heartbeat worker and intelengineparkheartbeat race to release the same engine-heartbeat.systole reques...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: net: stmmac: fix integer underflow in chain mode The jumbofrm function’s chain-mode implementation calculates len = nopagedlen - bmax without conditions. Here, nopagedlen = skbheadlenskb only linear bytes, and bmax is either...

Astra Linux – Vulnerability in cups

OpenPrinting CUPS is an open-source printing system for Linux and other Unix-like operating systems. In versions 2.4.16 and earlier, there was an integer underflow vulnerability in the ppdCreateFromIPP function cups/ppd-cache.c. This vulnerability allowed any unprivileged local user to crash the...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: drm/sun4i: dsi: Prevent underflow when calculating packet sizes. Currently, the packet overhead is subtracted using unsigned arithmetic. With a short sync pulse, this could lead to an underflow, causing the value to wrap around t...

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

In the Linux kernel, the following vulnerability has been resolved: can: j1939: j1939sessionnew: fix skb reference counting Since j1939sessionskbqueue performs an additional skbget operation for each new skb, doing the same operation for the initial skb in j1939sessionnew will prevent refcount...

Astra Linux – Vulnerability in gpsd

There is an integer underflow vulnerability in the nextstate function in gpsd/packet.c in gpsd versions prior to the commit ffa1d6f40bca0b035fc7f5e563160ebb67199da7. When parsing a NAVCOM packet, the payload length is calculated using lexer-length = sizetc - 4, without checking whether the input...

Astra Linux – Vulnerability in u-boot

A issue was discovered in Das U-Boot during the period from 2019.07. There is an unbounded memcpy operation when parsing a UDP packet, due to an underflow of the netprocessreceivedpacket integer during the udppackethandler call...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: xsk: fixed the refcount underflow in the error path. This fix addresses a refcount underflow issue reported by syzbot, which can occur when the system runs out of memory. If xpalloctxdescs fails—and it can only fail due to...

Astra Linux – Vulnerability in Capstone

Capstone is a disassembly framework. In versions 6.0.0-Alpha5 and earlier, a unchecked return from vsnprintf in SStreamconcat allowed a malicious csoptmem.vsnprintf to manipulate SStream’s index beyond its limit, resulting in a stack buffer underflow/overflow when the next write operation occurre...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: vsock/virtio: fixed the potential underflow in virtiotransportgetcredit. The credit calculation in virtiotransportgetcredit uses unsigned arithmetic: ret = vvs-peerbufalloc - vvs-txcnt - vvs-peerfwdcnt; If the peer reduces its...

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: btrfs: In the “send” operation, there is a issue with handling path ref underflow during the header iterate inoderef function. Change BUGON to proper error handling if building the path buffer fails. The pointers are not...

Astra Linux – Vulnerability in gnutls28

A flaw in GnuTLS’ DTLS handshake parsing allows for malformed fragments with zero length and non-zero offsets. This leads to an integer underflow during reassembly, resulting in an out-of-bounds read. This issue is remotely exploitable and could cause information disclosure or denial of service...
