Description
This security bulletin contains information about 10 secuirty vulnerabilities.
1) NULL pointer dereference (CVE-ID: CVE-2016-10209)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error in archive_string.c in libarchive allows remote attackers to trigger NULL pointer dereference and application crash via a specially crafted archive file.
2) Buffer over-read (CVE-ID: CVE-2016-10349)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error in the archive_le32dec function in archive_endian.h in libarchive. A remote attacker can trigger heap-based buffer over-read and application crash via a specially crafted file.
3) Buffer over-read (CVE-ID: CVE-2016-10350)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error in The archive_read_format_cab_read_header function in archive_read_support_format_cab.c in libarchive 3.2.2. A remote attacker can trigger heap-based buffer over-read and application crash via a specially crafted file.
4) Buffer over-read (CVE-ID: CVE-2017-14166)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error in libarchive 3.3.2. A remote attacker can trigger xml_data heap-based buffer over-read and application crash via a specially crafted xar archive, related to the mishandling of empty strings in the atol8 function in archive_read_support_format_xar.c.
5) Out-of-bounds read (CVE-ID: CVE-2017-14501)
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to out-of-bounds read condition in the parse_file_info function, as defined in the archive_read_support_format_iso9660.c source code file when extracting ISO 9660 files. A remote attacker can trick the victim into extracting an ISO 9660 file that submits malicious input and cause the service to crash.
6) Off-by-one (CVE-ID: CVE-2017-14502)
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to off-by-one error for UTF-16 names in RAR archives. A remote attacker can trigger an out-of-bounds read in archive_read_format_rar_read_header and cause the service to crash.
7) Out-of-bounds read (CVE-ID: CVE-2017-14503)
The vulnerability allows a remote attacker to cause DoS condition on the target system.The vulnerability exists due to out-of-bounds read within lha_read_data_none() in archive_read_support_format_lha.c when extracting a specially crafted lha archive. A remote attacker can trigger an out-of-bounds read, related to lha_crc16 and cause the service to crash.
8) Double-free error (CVE-ID: CVE-2018-1000877)
The vulnerability allows a remote attacker to cause DoS condition.
The vulnerability exists due to double-free error in RAR decoder - libarchive/archive_read_support_format_rar.c, parse_codes(), realloc(rar->lzss.window, new_size) with new_size = 0. A remote attacker can trick the victim into opening a specially crafted RAR archive and cause the service to crash.
9) Use-after-free error (CVE-ID: CVE-2018-1000878)
The vulnerability allows a remote attacker to cause DoS condition.
The vulnerability exists due to use-after-free error in RAR decoder - libarchive/archive_read_support_format_rar.c. A remote attacker can trick the victim into opening a specially crafted RAR archive and cause the service to crash.
10) Improper input validation (CVE-ID: CVE-2018-1000880)
The vulnerability allows a remote attacker to cause DoS condition.
The vulnerability exists due to insufficient validation of user-supplied input in WARC parser - libarchive/archive_read_support_format_warc.c, _warc_read() that can result in DoS - quasi-infinite run time and disk usage from tiny file. A remote attacker can trick the victim into opening a specially crafted RAR archive and cause the service to crash.
