The yr_arena_write_data function in YARA 3.6.1 allows remote attackers to cause a denial of service (buffer over-read and application crash) or obtain sensitive information from process memory via a crafted file that is mishandled in the yr_re_fast_exec function in libyara/re.c and the _yr_scan_match_callback function in libyara/scan.c.
AnalysisAI
The yr_arena_write_data function in YARA 3.6.1 allows remote attackers to cause a denial of service (buffer over-read and application crash) or obtain sensitive information from process memory via a. Rated high severity (CVSS 7.1), this vulnerability is no authentication required, low attack complexity. Public exploit code available.
Technical ContextAI
This vulnerability is classified as Out-of-bounds Read (CWE-125), which allows attackers to read data from memory outside the intended buffer boundaries. The yr_arena_write_data function in YARA 3.6.1 allows remote attackers to cause a denial of service (buffer over-read and application crash) or obtain sensitive information from process memory via a crafted file that is mishandled in the yr_re_fast_exec function in libyara/re.c and the _yr_scan_match_callback function in libyara/scan.c. Affected products include: Virustotal Yara.
RemediationAI
A vendor patch is available. Apply the latest security update as soon as possible. Validate array indices and buffer lengths. Use memory-safe languages. Enable AddressSanitizer during testing.
