CVE-2026-48132
The CVE-2026-48132 entry describes a vulnerability in Security Gateway where length values in certain IKE packets over NAT-T (UDP/4500) are not validated correctly. This can cause the VPN processing service to terminate unexpectedly, resulting in a denial-of-service (temporary interruption of VPN...
CVE-2026-8047
The affected products perform improper length checking when parsing incoming HTTP requests, resulting in a size-limited out-of-bounds write. An unauthenticated remote attacker can exploit this flaw to cause a denial of service via a system crash on the affected device...
gnutls: GnuTLS: Denial of Service via DTLS zero-length fragment
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...
gnutls: GnuTLS: Denial of Service via heap buffer overflow in DTLS handshake fragment reassembly
A heap buffer overflow vulnerability exists in the DTLS handshake fragment reassembly logic of GnuTLS. The issue arises in mergehandshakepacket where incoming handshake fragments are matched and merged based solely on handshake type, without validating that the messagelength field remains...

CVE-2026-8047
CVE-2026-8047 affects CODESYS Control. The flaw is an improper length check while parsing incoming HTTP requests, causing a size-limited out-of-bounds write. An unauthenticated remote attacker could trigger a denial of service via a system crash on the affected device. Exploitation details and re...

pyasn1: pyasn1 Vulnerable to Denial of Service via Unbounded Recursion
An unbounded recursion flaw has been discovered in the pypi pyasn1 library. This uncontrolled recursion occurs when decoding ASN.1 data with deeply nested structures. An attacker can supply a crafted payload containing nested SEQUENCE 0x30 or SET 0x31 tags with Indefinite Length 0x80 markers. Thi...
rsync: Rsync: Use-after-free vulnerability in extended attribute handling
A flaw was found in rsync. When rsync is configured to handle extended attributes using the -X or --xattrs option, a remote attacker can exploit a use-after-free vulnerability. This occurs because the receivexattr function incorrectly processes an untrusted length value during a sorting operation...
dnsmasq: Broken ECS source validation bypass
A validation bypass was discovered in dnsmasq's RFC 7871 client subnet ECS handling. When verifying ECS source information in DNS responses, dnsmasq passes the OPT record length instead of the full packet length to the validation function.This causes all internal bounds checks to fail, completely...
dnsmasq: NSEC bitmap parsing infinite loop
A denial of service vulnerability was discovered in dnsmasq's DNSSEC validation. When parsing NSEC and NSEC3 bitmap records, the window iteration logic fails to account for the 2-byte window header when advancing through the bitmap data. A specially crafted DNS response with a zero-length bitmap...
rsync: Rsync: Use-after-free vulnerability in extended attribute handling
A flaw was found in rsync. When rsync is configured to handle extended attributes using the -X or --xattrs option, a remote attacker can exploit a use-after-free vulnerability. This occurs because the receivexattr function incorrectly processes an untrusted length value during a sorting operation...
gimp: GIMP: Remote Code Execution via PSP file parsing
A flaw was found in GIMP. A remote attacker could exploit this vulnerability by enticing a user to open a specially crafted PSP PaintShop Pro file. This flaw is caused by a heap-based buffer overflow, where the application does not properly validate the length of user-supplied data. Successful...
Check Point Security Gateway 安全漏洞
Check Point Security Gateway is a series of network security gateway devices developed by Check Point Corporation in Israel. There is a security vulnerability in Check Point Security Gateway, which stems from incorrect validation of length values in specific IKE packets during NAT-T operations...
FastNetMon 安全漏洞
FastNetMon is a high-performance DDoS detector/sensor developed by Pavel Odintsov. It is built using multiple packet capture engines. Versions of FastNetMon Community Edition 1.2.9 and earlier contained security vulnerabilities. These vulnerabilities stemmed from the lack of prefix bit length...
