Description

This security bulletin contains information about 2 vulnerabilities.


1) Double free (CVE-ID: CVE-2025-5914)

CWE-ID: CWE-415 - Double Free

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the archive_read_format_rar_seek_data() function. A remote attacker can pass specially crafted data to the application, trigger a double free error and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


2) Heap-based buffer overflow (CVE-ID: CVE-2025-47436)

CWE-ID: CWE-122 - Heap-based Buffer Overflow

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:P/PR:H/UI:A/VC:L/VI:H/VA:H/SC:L/SI:H/SA:H/E:U/U:Clear


The vulnerability allows a local privileged user to cause memory corruption.

The vulnerability exists due to a boundary error in the ORC C++ LZO decompression logic, where specially crafted malformed ORC files can cause the decompressor to allocate a 250-byte buffer but then attempts to copy 295 bytes into it. A local privileged user can pass specially crafted data to the application, trigger a heap-based buffer overflow and cause memory corruption.
