Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: Security). Supported versions that are affected are Oracle Java SE: 8u481, 8u481-b50, 8u481-perf, 11.0.30, 17.0.18, 21.0.10, 25.0.2, 26; Oracle GraalVM for JDK: 17.0.18 and 21.0.10; Oracle GraalVM Enterprise Edition: 21.3.17. Difficult to exploit vulnerability allows unauthenticated attacker with logon to the infrastructure where Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition executes to compromise Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition. Successful attacks of this vulnerability can result in unauthorized read access to a subset of Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition accessible data. Note: This vulnerability can be exploited by using APIs in the specified Component, e.g., through a web service which supplies data to the APIs. This vulnerability also applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. CVSS 3.1 Base Score 2.9 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N).

Low
A flaw was found in OpenJDK. Because initial authentication challenges are transmitted in cleartext, a remote attacker intercepting network traffic can modify the iteration count during Kerberos authentication. This manipulation can enable key recovery, leading to sensitive information disclosure, or cause client authentication tools such as kinit to execute for an extended duration, resulting in a Denial of Service (DoS).

A flaw was found in openjdk. When compiling XPath expressions, the internal XML security manager is not properly initialized, failing to restrict external entity resolution. A remote attacker could exploit this vulnerability by supplying specially crafted XML input to trigger XML External Entity (XXE) injection or XML Entity Expansion (XEE). Successful exploitation primarily leads to unauthorized information disclosure, such as the exposure of sensitive local files, and can also cause a Denial of Service (DoS) through resource exhaustion.

A flaw was found in libpng, a reference library for processing PNG (Portable Network Graphics) image files. A local attacker could exploit a heap buffer over-read vulnerability in the `png_image_finish_read` function by tricking a user into processing a specially crafted interlaced 16-bit PNG file with an 8-bit output format and non-minimal row stride. This could lead to a denial of service (DoS) and potentially information disclosure.

A flaw was found in libpng, a reference library for PNG (Portable Network Graphics) raster image files. An integer truncation vulnerability exists in the png_write_image_16bit and png_write_image_8bit simplified write API functions. A local attacker could exploit this flaw by providing a negative row stride (for bottom-up image layouts) or a stride exceeding 65535 bytes, leading to a heap buffer over-read.

A heap based buffer overflow flaw has been discovered in LibPNG. Prior to version 1.6.55, an out-of-bounds read vulnerability exists in the png_set_quantize() API function. When the function is called with no histogram and the number of colors in the palette is more than twice the maximum supported by the user's display, certain palettes will cause the function to enter into an infinite loop that reads past the end of an internal heap-allocated buffer. The images that trigger this vulnerability are valid per the PNG specification.

A flaw was found in giflib. A remote attacker can exploit a buffer overflow vulnerability in the EGifGCBToExtension function by providing a specially crafted Graphics Control Extension (GCE) block. This allows overwriting an existing GCE block without proper size validation, leading to a denial of service (DoS) on the system.

Important
A flaw was found in libpng, a library used for processing PNG (Portable Network Graphics) image files. This vulnerability arises from improper memory management where a heap-allocated buffer is aliased between internal data structures. When specific functions are called, a freed memory region can still be referenced, leading to a use-after-free condition. An attacker could potentially exploit this to achieve arbitrary code execution or cause a denial of service.

A flaw was found in libpng. A remote attacker could exploit an out-of-bounds read and write vulnerability in the ARM/AArch64 Neon-optimized palette expansion path. This occurs when processing a final partial chunk of 8-bit paletted rows without verifying sufficient input pixels, leading to dereferencing pointers before the start of the row buffer and writing expanded pixel data to underflowed positions. This flaw can result in information disclosure and denial of service.

Impact
Low
A flaw was found in OpenJDK. A remote attacker can cause a Denial of Service (DoS) by inducing excessive processor utilization. When communicating over a Transport Layer Security (TLS) connection, if a remote server sends a connection closure notification but subsequently transmits additional data over the same connection before closing it, the receiving thread enters an infinite processing loop. This behavior causes the affected thread to consume 100% CPU, disrupting application performance and service availability.

Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition. Note: This vulnerability can be exploited by using APIs in the specified Component, e.g., through a web service which supplies data to the APIs. This vulnerability also applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security.

This occurs when processing a final partial chunk of 8-bit paletted rows without verifying sufficient input pixels, leading to dereferencing pointers before the start of the row buffer and writing expanded pixel data to underflowed positions. This flaw can result in information disclosure and denial of service.",
