The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
In Long Range Zip (aka lrzip) 0.631, there is a use-after-free in read_stream in stream.c, because decompress_file in lrzip.c lacks certain size validation.
3) Use-after-free (CVE-ID: CVE-2018-5747)
CWE-ID: CWE-416 - Use After Free
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
In Long Range Zip (aka lrzip) 0.631, there is a use-after-free in the ucompthread function (stream.c). Remote attackers could leverage this vulnerability to cause a denial of service via a crafted lrz file.
4) Buffer overflow (CVE-ID: CVE-2017-9928)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
In lrzip 0.631, a stack buffer overflow was found in the function get_fileinfo in lrzip.c:979, which allows attackers to cause a denial of service via a crafted file.
5) Buffer overflow (CVE-ID: CVE-2017-9929)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
In lrzip 0.631, a stack buffer overflow was found in the function get_fileinfo in lrzip.c:1074, which allows attackers to cause a denial of service via a crafted file.
6) Division by zero (CVE-ID: CVE-2017-8842)
CWE-ID: CWE-369 - Divide By Zero
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to divide-by-zero error within The bufRead::get() function in libzpaq/libzpaq.h in liblrzip.so in lrzip 0.631. A remote attacker can perform a denial of service (divide-by-zero error and application crash) via a crafted archive.
7) NULL pointer dereference (CVE-ID: CVE-2017-8843)
CWE-ID: CWE-476 - NULL Pointer Dereference
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error. A remote attacker can trigger denial of service conditions via a crafted archive.
8) Heap-based buffer overflow (CVE-ID: CVE-2017-8844)
CWE-ID: CWE-122 - Heap-based Buffer Overflow
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:Green
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in The read_1g function in stream.c in liblrzip.so in lrzip 0.631. A remote attacker can use a crafted archive. to trigger heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
9) Out-of-bounds read (CVE-ID: CVE-2017-8845)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
The lzo1x_decompress function in lzo1x_d.ch in LZO 2.08, as used in lrzip 0.631, allows remote attackers to cause a denial of service (invalid memory read and application crash) via a crafted archive.
10) Use-after-free (CVE-ID: CVE-2017-8846)
CWE-ID: CWE-416 - Use After Free
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error when processing a crafted archive. A remote attackers can cause a denial of service (use-after-free and application crash).
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
11) NULL pointer dereference (CVE-ID: CVE-2017-8847)
CWE-ID: CWE-476 - NULL Pointer Dereference
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error. A remote attacker can trigger denial of service conditions via a crafted archive.
12) NULL pointer dereference (CVE-ID: CVE-2021-27345)
CWE-ID: CWE-476 - NULL Pointer Dereference
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear
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 the ucompthread in stream.c. A remote attacker can trick the victim to open a specially crafted compressed file and trigger denial of service conditions.
13) Use-after-free (CVE-ID: CVE-2021-27347)
