Description

The remote host is affected by the vulnerability described in GLSA-202406-04 (LZ4: Memory Corruption)

 An attacker who submits a crafted file to an application linked with lz4 may be able to trigger an integer overflow, leading to calling of memmove() on a negative size argument, causing an out-of-bounds write and/or a crash.

Tenable has extracted the preceding description block directly from the Gentoo Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

 # emerge --sync # emerge --ask --oneshot --verbose >=app-arch/lz4-1.9.3-r1
