Описание
libarchive through 3.7.7 has a heap-based buffer over-read in header_gnu_longlink in archive_read_support_format_tar.c via a TAR archive because it mishandles truncation in the middle of a GNU long linkname.
A flaw was found in the libarchive library. A specially-crafted tar file may trigger a head-based buffer over-read condition due to incorrect handling of truncation in the middle of a long GNU linkname. This issue can cause an application crash leading to a denial of service.
Отчет
Within regulated environments, a combination of the following controls acts as a significant barrier to successfully exploiting a CWE-126: Buffer Over-read vulnerability and therefore downgrades the severity of this particular CVE from Moderate to Low. Memory access boundaries are enforced through secure coding practices, including bounds checking and automated detection of over-read conditions during development. Static analysis and peer reviews catch improper memory handling early, reducing the risk of vulnerabilities reaching production. Memory protection mechanisms restrict access to allocated regions at runtime, and process isolation contains memory faults within the affected workload. Additionally, a defense-in-depth monitoring strategy supports real-time detection of anomalous memory activity, enabling rapid response and limiting potential impact.
