| CVE-2026-42170 | 2 Gimp, Redhat | 3 Gimp, Enterprise Linux, Rhel Els | 2026-11-04 | 7.8 High |
| A heap-based buffer overflow vulnerability exists in the GIMP DDS (DirectDraw Surface) file parser. When a crafted DDS file declares a D3D9 pixel format but sets a lower bits-per-pixel (bpp) value in the header, the loader allocates an undersized heap buffer. Subsequent pixel data consumption at the real format's stride causes a write past the heap buffer boundary, leading to heap metadata corruption and potential code execution. | ||||

| CVE-2026-33846 | 2 Gnu, Redhat | 18 Gnutls, Ai Inference Server, Cert Manager and 15 more | 2026-11-04 | 7.5 High |
| A heap buffer overflow vulnerability exists in the DTLS handshake fragment reassembly logic of GnuTLS. The issue arises in merge_handshake_packet() where incoming handshake fragments are matched and merged based solely on handshake type, without validating that the message_length field remains consistent across all fragments of the same logical message. An attacker can exploit this by sending crafted DTLS fragments with conflicting message_length values, causing the implementation to allocate a buffer based on a smaller initial fragment and subsequently write beyond its bounds using larger, inconsistent fragments. Because the merge operation does not enforce proper bounds checking against the allocated buffer size, this results in an out-of-bounds write on the heap. The vulnerability is remotely exploitable without authentication via the DTLS handshake path and can lead to application crashes or potential memory corruption. | ||||
| CVE-2026-33845 | 2 Gnu, Redhat | 18 Gnutls, Ai Inference Server, Cert Manager and 15 more | 2026-11-04 | 7.5 High |
| A flaw in GnuTLS DTLS handshake parsing allows malformed fragments with zero length and non-zero offset, leading to an integer underflow during reassembly and resulting in an out-of-bounds read. This issue is remotely exploitable and may cause information disclosure or denial of service. | ||||
| CVE-2025-9900 | 1 Redhat | 10 Ai Inference Server, Discovery, Enterprise Linux and 7 more | 2026-11-04 | 8.8 High |
| A flaw was found in Libtiff. This vulnerability is a "write-what-where" condition, triggered when the library processes a specially crafted TIFF image file. By providing an abnormally large image height value in the file's metadata, an attacker can trick the library into writing attacker-controlled color data to an arbitrary memory location. This memory corruption can be exploited to cause a denial of service (application crash) or to achieve arbitrary code execution with the permissions of the user. | ||||
| CVE-2025-4948 | 1 Redhat | 6 Enterprise Linux, Rhel Aus, Rhel E4s and 3 more | 2026-11-04 | 7.5 High |
| A flaw was found in the soup_multipart_new_from_message() function of the libsoup HTTP library, which is commonly used by GNOME and other applications to handle web communications. The issue occurs when the library processes specially crafted multipart messages. Due to improper validation, an internal calculation can go wrong, leading to an integer underflow. This can cause the program to access invalid memory and crash. As a result, any application or server using libsoup could be forced to exit unexpectedly, creating a denial-of-service (DoS) risk. | ||||
| CVE-2026-121965 | 2 Parse Community, Parseplatform | 2 Parse Server, Parse-server | 2026-11-04 | 5.3 Medium |
| Parse Server before 8.6.113 and 9.0.0 before 9.10.6-alpha.5 contains a prototype pollution vulnerability when building objects for Cloud Code triggers and LiveQuery, where a dot notation key whose intermediate segment resolves through an inherited member writes onto a process-wide built-in. Clients with write access to an object in a class with a trigger or LiveQuery can corrupt a built-in function, making unrelated requests fail until restart and denying service to all clients and hosted applications. | ||||
| CVE-2026-19389 | 1 Redhat | 5 Enterprise Linux, Enterprise Linux Eus, Rhel E4s and 2 more | 2026-11-04 | 7.1 High |
| Multiple integer overflow and underflow vulnerabilities were found in the GStreamer gst-plugins-ugly ASF demuxer (asfdemux) when parsing header objects from crafted ASF, WMV, or WMA files. Insufficient validation of attacker-controlled length and size values can bypass bounds checks and cause out-of-bounds heap reads. This can result in application crash, denial of service, or limited information disclosure when untrusted media is processed. | ||||
| CVE-2026-18917 | 1 Redhat | 10 Enterprise Linux, Enterprise Linux Eus, Enterprise Linux Nvidia and 7 more | 2026-11-04 | 7.8 High |
| A flaw was found in libvirt. An unprivileged local user could exploit an integer overflow vulnerability in the NodeGetFreePages RPC handler. This flaw allows crafted values to bypass a size check, leading to an undersized memory buffer. Subsequently, real NUMA node data can overwrite this buffer. This heap buffer overflow can corrupt the root libvirt daemon's memory, potentially leading to a denial of service or local privilege escalation. | ||||
| CVE-2026-18355 | 1 Redhat | 10 Directory Server, Directory Server E4s, Enterprise Linux and 7 more | 2026-11-04 | 7.5 High |
| A heap buffer overflow flaw was found in the SASL I/O layer of 389 Directory Server (389-ds-base). In sasl_io_start_packet(), the wrapped-record length read from the wire is validated only against an upper bound. A small wire length (0, 1, or 2) produces an encrypted_buffer_count below the already-consumed encrypted_buffer_offset, causing an unsigned subtraction underflow in sasl_io_read_packet(). PR_Recv is then requested to read approximately 4 GiB into a 1024-byte heap buffer, resulting in a heap buffer overflow with attacker-controlled content. After a successful SASL bind with integrity protection (SSF > 0), a remote authenticated attacker can cause a denial of service or potentially achieve remote code execution. This flaw is distinct from CVE-2026-11774, whose fix only guards against upper-bound overflow. | ||||
| CVE-2026-16529 | 1 Redhat | 10 Enterprise Linux, Enterprise Linux Eus, Openshift and 7 more | 2026-11-04 | 7.5 High |
| A signed integer overflow in the PCP __pmGetPDU() function can be exploited via crafted network packets during PDU processing or SASL negotiation. This permanently blinds the affected daemon, resulting in a total denial of service (DoS) for subsequent packet reads. | ||||
| CVE-2026-1761 | 1 Redhat | 9 Enterprise Linux, Enterprise Linux Eus, Openshift Devspaces and 6 more | 2026-11-04 | 8.6 High |
| A flaw was found in libsoup. This stack-based buffer overflow vulnerability occurs during the parsing of multipart HTTP responses due to an incorrect length calculation. A remote attacker can exploit this by sending a specially crafted multipart HTTP response, which can lead to memory corruption. This issue may result in application crashes or arbitrary code execution in applications that process untrusted server responses, and it does not require authentication or user interaction. | ||||
| CVE-2026-120830 | 1 Redhat | 2 Enterprise Linux, Openshift | 2026-11-04 | 7.4 High |
| A flaw was found in libslirp in icmp_forward_error(). When building an ICMP error response, the length of the quoted original IPv4 packet was taken from the IP header without clamping it to the actual buffer length. A truncated or malformed packet could cause an out-of-bounds heap read, leaking host memory into the ICMP error packet returned to a guest or container. | ||||
