CVE-2023-3354 3 Fedoraproject, Qemu, Redhat 4 Fedora, Qemu, Enterprise Linux and 1 more 2024-03-11 N/A 7.5 HIGH
A flaw was found in the QEMU built-in VNC server. When a client connects to the VNC server, QEMU checks whether the current number of connections crosses a certain threshold and if so, cleans up the previous connection. If the previous connection happens to be in the handshake phase and fails, QEMU cleans up the connection again, resulting in a NULL pointer dereference issue. This could allow a remote unauthenticated client to cause a denial of service.
CVE-2023-3164 2 Libtiff, Redhat 2 Libtiff, Enterprise Linux 2024-03-08 N/A 5.5 MEDIUM
A heap-buffer-overflow vulnerability was found in LibTIFF, in extractImageSection() at tools/tiffcrop.c:7916 and tools/tiffcrop.c:7801. This flaw allows attackers to cause a denial of service via a crafted tiff file.
CVE-2019-15604 5 Debian, Nodejs, Opensuse and 2 more 10 Debian Linux, Node.js, Leap and 7 more 2024-03-07 5.0 MEDIUM 7.5 HIGH

CVE-2023-1192 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2024-03-07 N/A 6.5 MEDIUM
A use-after-free flaw was found in smb2_is_status_io_timeout() in CIFS in the Linux Kernel. After CIFS transfers response data to a system call, there are still local variable points to the memory region, and if the system call frees it faster than CIFS uses it, CIFS will access a free memory region, leading to a denial of service.
CVE-2021-3621 2 Fedoraproject, Redhat 8 Fedora, Sssd, Enterprise Linux and 5 more 2024-03-04 9.3 HIGH 8.8 HIGH
A flaw was found in SSSD, where the sssctl command was vulnerable to shell command injection via the logs-fetch and cache-expire subcommands. This flaw allows an attacker to trick the root user into running a specially crafted sssctl command, such as via sudo, to gain root access. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
CVE-2019-11478 6 Canonical, F5, Ivanti and 3 more 24 Ubuntu Linux, Big-ip Access Policy Manager, Big-ip Advanced Firewall Manager and 21 more 2024-02-27 5.0 MEDIUM 7.5 HIGH
Jonathan Looney discovered that the TCP retransmission queue implementation in tcp_fragment in the Linux kernel could be fragmented when handling certain TCP Selective Acknowledgment (SACK) sequences. A remote attacker could use this to cause a denial of service. This has been fixed in stable kernel releases 4.4.182, 4.9.182, 4.14.127, 4.19.52, 5.1.11, and is fixed in commit f070ef2ac66716357066b683fb0baf55f8191a2e.
CVE-2019-11477 6 Canonical, F5, Ivanti and 3 more 24 Ubuntu Linux, Big-ip Access Policy Manager, Big-ip Advanced Firewall Manager and 21 more 2024-02-27 7.8 HIGH 7.5 HIGH
Jonathan Looney discovered that the TCP_SKB_CB(skb)->tcp_gso_segs value was subject to an integer overflow in the Linux kernel when handling TCP Selective Acknowledgments (SACKs). A remote attacker could use this to cause a denial of service. This has been fixed in stable kernel releases 4.4.182, 4.9.182, 4.14.127, 4.19.52, 5.1.11, and is fixed in commit 3b4929f65b0d8249f19a50245cd88ed1a2f78cff.
CVE-2023-51767 3 Fedoraproject, Openbsd, Redhat 3 Fedora, Openssh, Enterprise Linux 2024-02-27 N/A 7.0 HIGH
OpenSSH through 9.6, when common types of DRAM are used, might allow row hammer attacks (for authentication bypass) because the integer value of authenticated in mm_answer_authpassword does not resist flips of a single bit. NOTE: this is applicable to a certain threat model of attacker-victim co-location in which the attacker has user privileges.
CVE-2023-50781 2 M2crypto Project, Redhat 3 M2crypto, Enterprise Linux, Update Infrastructure 2024-02-26 N/A 7.5 HIGH
A flaw was found in m2crypto. This issue may allow a remote attacker to decrypt captured messages in TLS servers that use RSA key exchanges, which may lead to exposure of confidential or sensitive data.
CVE-2023-1289 3 Fedoraproject, Imagemagick, Redhat 4 Extra Packages For Enterprise Linux, Fedora, Imagemagick and 1 more 2024-02-22 N/A 5.5 MEDIUM
A vulnerability was discovered in ImageMagick where a specially created SVG file loads itself and causes a segmentation fault. This flaw allows a remote attacker to pass a specially crafted SVG file that leads to a segmentation fault, generating many trash files in "/tmp," resulting in a denial of service. When ImageMagick crashes, it generates a lot of trash files. These trash files can be large if the SVG file contains many render actions. In a denial of service attack, if a remote attacker uploads an SVG file of size t, ImageMagick generates files of size 103*t. If an attacker uploads a 100M SVG, the server will generate about 10G.
CVE-2019-14821 8 Canonical, Debian, Fedoraproject and 5 more 38 Ubuntu Linux, Debian Linux, Fedora and 35 more 2024-02-16 7.2 HIGH 8.8 HIGH
An out-of-bounds access issue was found in the Linux kernel, all versions through 5.3, in the way Linux kernel's KVM hypervisor implements the Coalesced MMIO write operation. It operates on an MMIO ring buffer 'struct kvm_coalesced_mmio' object, wherein write indices 'ring->first' and 'ring->last' value could be supplied by a host user-space process. An unprivileged host user or process with access to '/dev/kvm' device could use this flaw to crash the host kernel, resulting in a denial of service or potentially escalating privileges on the system.
CVE-2008-0411 6 Debian, Ghostscript, Mandrakesoft and 3 more 14 Debian Linux, Ghostscript, Mandrake Linux and 11 more 2024-02-16 6.8 MEDIUM N/A
Stack-based buffer overflow in the zseticcspace function in zicc.c in Ghostscript 8.61 and earlier allows remote attackers to execute arbitrary code via a postscript (.ps) file containing a long Range array in a .seticcspace operator.
CVE-2013-1591 2 Palemoon, Redhat 3 Pale Moon, Enterprise Linux, Enterprise Virtualization 2024-02-15 10.0 HIGH 9.8 CRITICAL
Stack-based buffer overflow in libpixman, as used in Pale Moon before 15.4 and possibly other products, has unspecified impact and context-dependent attack vectors. NOTE: this issue might be resultant from an integer overflow in the fast_composite_scaled_bilinear function in pixman-inlines.h, which triggers an infinite loop.
CVE-2004-0112 24 4d, Apple, Avaya and 21 more 65 Webstar, Mac Os X, Mac Os X Server and 62 more 2024-02-15 5.0 MEDIUM N/A
The SSL/TLS handshaking code in OpenSSL 0.9.7a, 0.9.7b, and 0.9.7c, when using Kerberos ciphersuites, does not properly check the length of Kerberos tickets during a handshake, which allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that causes an out-of-bounds read.
CVE-2009-4272 2 Linux, Redhat 7 Linux Kernel, Enterprise Linux, Enterprise Linux Desktop and 4 more 2024-02-15 7.8 HIGH 7.5 HIGH
A certain Red Hat patch for net/ipv4/route.c in the Linux kernel 2.6.18 on Red Hat Enterprise Linux (RHEL) 5 allows remote attackers to cause a denial of service (deadlock) via crafted packets that force collisions in the IPv4 routing hash table, and trigger a routing "emergency" in which a hash chain is too long. NOTE: this is related to an issue in the Linux kernel before 2.6.31, when the kernel routing cache is disabled, involving an uninitialized pointer and a panic.
CVE-2008-4302 3 Debian, Linux, Redhat 3 Debian Linux, Linux Kernel, Enterprise Linux 2024-02-15 4.9 MEDIUM 5.5 MEDIUM
fs/splice.c in the splice subsystem in the Linux kernel before 2.6.22.2 does not properly handle a failure of the add_to_page_cache_lru function, and subsequently attempts to unlock a page that was not locked, which allows local users to cause a denial of service (kernel BUG and system crash), as demonstrated by the fio I/O tool.
CVE-2006-4342 1 Redhat 1 Enterprise Linux 2024-02-15 4.0 MEDIUM 5.5 MEDIUM
The kernel in Red Hat Enterprise Linux 3, when running on SMP systems, allows local users to cause a denial of service (deadlock) by running the shmat function on an shm at the same time that shmctl is removing that shm (IPC_RMID), which prevents a spinlock from being unlocked.
CVE-2024-0639 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2024-02-14 N/A 5.5 MEDIUM
A denial of service vulnerability due to a deadlock was found in sctp_auto_asconf_init in net/sctp/socket.c in the Linux kernel’s SCTP subsystem. This flaw allows guests with local user privileges to trigger a deadlock and potentially crash the system.
