Several security vulnerabilities have been discovered in lrzip, a compression program. Heap-based and stack buffer overflows, use-after-free and infinite loops would allow attackers to cause a denial of service or possibly other unspecified impact via a crafted compressed file.

CVE-2017-8842

The bufRead::get() function in libzpaq/libzpaq.h allows remote attackers to cause a denial of service (divide-by-zero error and application crash) via a crafted archive.

CVE-2017-8843

The join_pthread function in stream.c allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted archive.

CVE-2017-8844

The read_1g function in stream.c allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted archive.

CVE-2017-8845

The lzo1x_decompress function in lzo1x_d.ch in LZO, as used in lrzip, allows remote attackers to cause a denial of service (invalid memory read and application crash) via a crafted archive.

CVE-2017-8846

The read_stream function in stream.c allows remote attackers to cause a denial of service (use-after-free and application crash) via a crafted archive.

CVE-2017-8847

The bufRead::get() function in libzpaq/libzpaq.h allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted archive.

CVE-2017-9928

A stack buffer overflow was found in the function get_fileinfo, which allows attackers to cause a denial of service via a crafted file.

CVE-2017-9929

A stack buffer overflow was found in the function get_fileinfo, which allows attackers to cause a denial of service via a crafted file.

CVE-2018-5650

There is an infinite loop and application hang in the unzip_match function in runzip.c. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted lrz file.

CVE-2018-5747

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.

CVE-2018-5786

There is an infinite loop and application hang in the get_fileinfo function (lrzip.c). Remote attackers could leverage this vulnerability to cause a denial of service via a crafted lrz file.

CVE-2018-9058

There is an infinite loop in the runzip_fd function of runzip.c. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted lrz file.

CVE-2018-10685

There is a use-after-free in the lzma_decompress_buf function of stream.c, which allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact.

CVE-2018-11496

There is a use-after-free in read_stream in stream.c, because decompress_file in lrzip.c lacks certain size validation.

CVE-2020-25467

A null pointer dereference was discovered lzo_decompress_buf in stream.c which allows an attacker to cause a denial of service (DOS) via a crafted compressed file.

CVE-2021-27345

A null pointer dereference was discovered in ucompthread in stream.c which allows attackers to cause a denial of service (DOS) via a crafted compressed file.

CVE-2021-27347

Use after free in lzma_decompress_buf function in stream.c in allows attackers to cause Denial of Service (DoS) via a crafted compressed file.

CVE-2022-26291

lrzip was discovered to contain a multiple concurrency use-after-free between the functions zpaq_decompress_buf() and clear_rulist(). This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted lrz file.

For Debian 8 jessie, these problems have been fixed in version 0.616-1+deb8u1.

We recommend that you upgrade your lrzip packages.
