hicolor

A heap buffer overflow in the function png_quantize() of hicolor v0.5.0 allows attackers to cause a Denial of Service (DoS) via a crafted PNG file.

CVE-2024-41440 identifies a heap-based buffer overflow vulnerability in the png_quantize() function of the hicolor library version 0.5.0. The png_quantize() function is responsible for color quantization of PNG images, a process that reduces the number of colors to optimize image size or compatibility. The vulnerability stems from improper bounds checking when handling input data during quantization, allowing a crafted PNG file to overflow a heap buffer. This overflow can corrupt memory, leading to application crashes and denial of service conditions. The vulnerability does not require any privileges or user interaction, making it easier to exploit in automated or remote scenarios where untrusted PNG files are processed. The CVSS 3.1 base score is 6.2, reflecting a medium severity with an attack vector limited to local (AV:L), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), and impact limited to availability (A:H) without affecting confidentiality or integrity. No known exploits have been reported in the wild, and no patches have been released at the time of publication. The CWE classification is CWE-122 (Heap-based Buffer Overflow), a common and critical memory corruption issue. This vulnerability primarily threatens applications or services that utilize hicolor for PNG image processing, especially those that handle untrusted or user-supplied images. Exploitation results in denial of service, potentially disrupting services or crashing applications that rely on this library.

CVE-2024-41440: n/a

A heap buffer overflow in the function cp_block() (/vendor/cute_png.h) of hicolor v0.5.0 allows attackers to cause a Denial of Service (DoS) via a crafted PNG file.

CVE-2024-41439 identifies a heap buffer overflow vulnerability in the cp_block() function within the /vendor/cute_png.h file of the hicolor library version 0.5.0. The vulnerability arises due to improper bounds checking when processing PNG image data, allowing an attacker to craft a malicious PNG file that triggers a buffer overflow on the heap. This overflow can corrupt memory, leading to a Denial of Service (DoS) by crashing the application or potentially the host system. The vulnerability is classified under CWE-787 (Out-of-bounds Write). Exploitation requires local access and user interaction, as the malicious PNG must be opened or processed by the vulnerable software. The CVSS v3.1 base score is 5.5 (medium severity), reflecting the limited attack vector (local), low complexity, no privileges required, but requiring user interaction. There is no impact on confidentiality or integrity, only availability. No patches or fixes have been published at the time of disclosure, and no known exploits are reported in the wild. The vulnerability affects software components that incorporate hicolor 0.5.0 for PNG processing, which may be embedded in various multimedia or graphical applications.

CVE-2024-41439: n/a

A heap buffer overflow in the function cp_stored() (/vendor/cute_png.h) of hicolor v0.5.0 allows attackers to cause a Denial of Service (DoS) via a crafted PNG file.

CVE-2024-41438 identifies a heap-based buffer overflow vulnerability in the cp_stored() function within the cute_png.h component of the hicolor library version 0.5.0. This vulnerability arises from improper bounds checking when processing PNG image data, allowing a crafted PNG file to overflow a heap buffer. The overflow leads to memory corruption that causes the affected application to crash, resulting in a denial of service (DoS) condition. The vulnerability is classified under CWE-122 (Heap-based Buffer Overflow). According to the CVSS v3.1 scoring, it has a score of 6.2 (medium severity), with an attack vector of local (AV:L), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), and impacts only availability (A:H) with no confidentiality or integrity impact. No patches or fixes have been published at the time of disclosure, and no known exploits have been reported in the wild. The vulnerability primarily affects applications or systems that utilize the hicolor v0.5.0 library to parse PNG files, especially where untrusted or user-supplied images are processed. Exploitation requires the attacker to supply a malicious PNG file to the vulnerable application, which then triggers the heap overflow during image parsing. This can cause the application to crash, denying service to legitimate users. While this vulnerability does not allow code execution or data theft, the resulting denial of service can disrupt operations in environments relying on the affected library for image processing.
