Name of the Vulnerable Software and Affected Versions
Lrzip version 0.621
Description
A null pointer dereference was discovered in the
lzo decompress buf function in stream.c, which allows an attacker to cause a denial of service (DOS) via a crafted compressed file. This issue can be exploited by a remote attacker to disrupt service using a specially crafted compressed file.Recommendations
For Lrzip version 0.621, consider avoiding the use of the
lzo decompress buf function in stream.c until a patch is available. As a temporary workaround, restrict the handling of compressed files from untrusted sources to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.Exploit
