ISC BIND 9 is a domain name system software developed by the ISC organization. ISC BIND 9 has a security vulnerability that stems from an unlimited recursive loop within the resolver’s state machine. This vulnerability could allow remote unauthenticated attackers to cause severe resource...

CVE-2026-32739

A flaw was found in libheif, a HEIF and AVIF file format decoder and encoder. A remote attacker could exploit this vulnerability by providing a specially crafted HEIF High Efficiency Image File Format sequence file. This would trigger an infinite loop during file parsing, consuming 100% CPU...

freerdp: FreeRDP: Denial of Service via endless blocking loop in Stream_EnsureCapacity

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol. The StreamEnsureCapacity function can create an endless blocking loop, leading to a Denial of Service DoS. This vulnerability can be exploited on 32-bit systems where the available physical memory is greater than o...

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...

Infinite loop

Overview Affected versions of this package are vulnerable to Infinite loop in the getsampleduration function. An attacker can cause the application to enter an infinite loop and consume excessive CPU resources by providing a specially crafted HEIF file during file parsing. Remediation A fix was...

DEBIAN-CVE-2026-32739

libheif is a HEIF and AVIF file format decoder and encoder. In versions 1.21.2 and below, a crafted 800-byte HEIF sequence file causes an infinite loop in Boxstts::getsampleduration, consuming 100% CPU indefinitely with zero progress, leading to DoS. The loop has no iteration limit or timeout and...

Dasel: Denial of service in dasel selector lexer due to infinite loop on unterminated regex literal

Summary dasel's selector lexer enters a non-terminating loop when tokenizing an unterminated regex pattern such as r/abc. A 2-byte input r/ is sufficient to cause the tokenizer to consume 100% CPU on one core indefinitely. I confirmed the issue on v3.3.1 fba653c7f248aff10f2b89fca93929b64707dfc8 a...
