Package : lrzip
Version : 0.631-1+deb9u2
CVE ID : CVE-2018-5786 CVE-2020-25467 CVE-2021-27345 CVE-2021-27347
CVE-2022-26291
Debian Bug : 888506 990583
Several security vulnerabilities have been discovered in lrzip, a
compression program. Invalid pointers, 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-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-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 9 stretch, these problems have been fixed in version
0.631-1+deb9u2.
We recommend that you upgrade your lrzip packages.
