Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 9 host has a package installed that is affected by multiple vulnerabilities as referenced in the dla-2981 advisory.

 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.
