HdrHistogram: HdrHistogram: Denial of Service via uncontrolled memory allocation

A flaw was found in HdrHistogram. A local attacker can exploit a vulnerability in the decodeFromCompressedByteBuffer function by manipulating the lengthOfCompressedContents argument. This manipulation leads to uncontrolled memory allocation, which can result in a Denial of Service DoS condition,...

Name of the Vulnerable Software and Affected Versions HAProxy versions prior to 3.4.0 Description An integer overflow exists in the drl field of the fcgi conn structure within the FastCGI parser. When the contentLength is 65535 and the paddingLength is 1 or more, the drl field wraps to 0. This...

PT-2026-54003

Name of the Vulnerable Software and Affected Versions pypdf versions prior to 6.13.3 Description A flaw in the library allows a maliciously crafted PDF to cause a Denial of Service DoS. This occurs when the system parses a content stream that lacks a /Length value, causing the MAX DECLARED STREAM...

Siemens RuggedCom Rox Heap-based Buffer Overflow (CVE-2022-2347)

There exists an unchecked length field in UBoot. The U-Boot DFU implementation does not bound the length field in USB DFU download setup packets, and it does not verify that the transfer direction corresponds to the specified command. Consequently, if a physical attacker crafts a USB DFU download...

netty-codec-haproxy: Netty-codec-haproxy: Denial of Service via malformed HAProxy message

A flaw was found in netty-codec-haproxy, a component of the Netty network application framework. A remote attacker can exploit this vulnerability by sending a specially crafted HAProxy message with a malformed PP2TYPESSL TLV Type-Length-Value header. This can lead to an IndexOutOfBoundsException...
