Detection & IOCsextracted from sources · hover to see the quote
- →Trigger condition is processing a specially crafted RAR archive file; monitor applications using libarchive for crashes or anomalous behavior when opening RAR files. ↗
- →The vulnerable function is execute_filter_e8 in the RAR format reader; stack traces or crash dumps referencing this function in libarchive are indicative of exploitation attempts. ↗
- →The vulnerability is in the RAR e8 filter code path; focus detection on libarchive-linked applications (e.g., file managers, archivers) processing RAR archives and crashing. ↗
- →User interaction is required — the attack vector involves a user opening a malicious RAR file; monitor for unexpected process crashes in libarchive-linked applications after RAR file open events. ↗
- ·Red Hat Enterprise Linux 6, 7, 8, and 9 ship versions of libarchive that do NOT contain the vulnerable code; the vulnerable code was introduced in a newer version of libarchive. Detection efforts on RHEL should focus on non-default or third-party libarchive installations. ↗
- ·Red Hat rates this as denial-of-service only (no confirmed RCE PoC); the RCE classification is specific to the Windows context. Adjust severity scoring accordingly for Linux environments. ↗
- ·On Windows, the vulnerability is tracked separately as CVE-2024-20697 and affects the Windows Compressed Folder component; patched via KB5036893 and KB5036910. ↗

CVE-2024-26256 [HIGH] CWE-122 Libarchive Remote Code Execution Vulnerability
Libarchive Remote Code Execution Vulnerability
FAQ: According to the CVSS metric, the attack vector is local (AV:L). Why does the CVE title indicate that this is a remote code execution?
The word Remote in the title refers to the location of the attacker. This type of exploit is sometimes referred to as Arbitrary Code Execution (ACE). The attack itself is carried out locally. This means an attacker or victim needs to execute code from the local machine to exploit the vulnerability.
FAQ: According to the CVSS metric, user interaction is required (UI:R) and privileges required are none (PR:N). What does that mean for this vulnerability?
An unauthorized attacker must wait for a user to initiate a connection.

CVE-2024-26256 [HIGH] CWE-122 libarchive: Heap based buffer overflow in rar e8 filter
libarchive: Heap based buffer overflow in rar e8 filter
Libarchive Remote Code Execution Vulnerability
A flaw was found in the libarchive library. A heap-based buffer overflow in the execute_filter_e8 function in the libarchive/archive_read_support_format_rar.c file can be triggered when a specially crafted RAR archive is processed, causing a crash to the application linked to the library, and resulting in a denial of service.
Statement: The remote code execution is only mentioned in Windows context without any evidence or PoC. As this issue is only a small buffer over-read, without impact to integrity or confidentiality, this flaw was rated as causing only a denial of service to the application linked to the libarchive library.
Additionally, libarchive as shipped in Red Hat Enterprise
