Heap-based buffer overflow in the parse_unicode_node function in bplist.c in libimobiledevice libplist 1.12 allows local users to cause a denial of service (out-of-bounds write) and possibly code execution via a crafted plist file.
AnalysisAI
Heap-based buffer overflow in the parse_unicode_node function in bplist.c in libimobiledevice libplist 1.12 allows local users to cause a denial of service (out-of-bounds write) and possibly code. Rated high severity (CVSS 7.3), this vulnerability is low attack complexity. Public exploit code available and no vendor patch available.
Technical ContextAI
This vulnerability is classified as Out-of-bounds Write (CWE-787), which allows attackers to write data beyond allocated buffer boundaries leading to code execution or crashes. Heap-based buffer overflow in the parse_unicode_node function in bplist.c in libimobiledevice libplist 1.12 allows local users to cause a denial of service (out-of-bounds write) and possibly code execution via a crafted plist file. Affected products include: Libplist Project Libplist.
RemediationAI
No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Validate write boundaries, use memory-safe languages, enable compiler protections (ASLR, stack canaries).
