zziplib

A Stack Buffer Overflow vulnerability in zziplibv 0.13.77 allows attackers to cause a denial of service via the __zzip_fetch_disk_trailer() function at /zzip/zip.c.

CVE-2024-39134 identifies a stack-based buffer overflow vulnerability in zziplib version 0.13.77, a widely used open-source library for reading ZIP archives. The vulnerability exists in the __zzip_fetch_disk_trailer() function located in the source file /zzip/zip.c. This function is responsible for fetching the disk trailer of a ZIP archive, and due to improper bounds checking or unsafe handling of input data, an attacker can overflow a stack buffer. This overflow can lead to a denial of service condition by crashing the application that uses this library. The vulnerability does not impact confidentiality or integrity, as it does not allow code execution or data leakage, but it does affect availability. The CVSS v3.1 score is 7.5 (high), reflecting the network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), no impact on confidentiality or integrity (C:N/I:N), and high impact on availability (A:H). No patches or fixes have been linked yet, and no exploits are known in the wild, but the vulnerability is publicly disclosed and should be considered a significant risk for denial of service attacks in environments using the affected zziplib version.

CVE-2024-39134: n/a

Heap Buffer Overflow vulnerability in zziplib v0.13.77 allows attackers to cause a denial of service via the __zzip_parse_root_directory() function at /zzip/zip.c.

CVE-2024-39133 identifies a heap-based buffer overflow vulnerability in the zziplib library version 0.13.77, specifically within the __zzip_parse_root_directory() function located in the source file /zzip/zip.c. zziplib is an open-source C library used for reading ZIP archives, commonly integrated into various software and embedded systems for ZIP file handling. The vulnerability arises when the function improperly handles or parses the root directory structure of a ZIP archive, leading to an out-of-bounds write on the heap memory. This heap overflow can corrupt memory, causing the application to crash, resulting in a denial of service (DoS) condition. The vulnerability requires an attacker to supply a crafted ZIP file to the vulnerable system, which then triggers the overflow during parsing. According to the CVSS v3.1 vector, the attack vector is network-based (AV:N), with low attack complexity (AC:L), requiring low privileges (PR:L), no user interaction (UI:N), and affects availability only (A:L) without impacting confidentiality or integrity. No known exploits have been reported in the wild, and no official patches have been released at the time of publication. The weakness is categorized under CWE-122 (Heap-based Buffer Overflow), a common memory corruption issue that can lead to stability and security problems. The vulnerability's medium severity score (4.3) reflects its limited impact scope and exploitation requirements. Organizations using zziplib, especially in environments processing untrusted ZIP files, should be aware of this flaw and prepare to apply patches or mitigations once available.
