Description D'juan McDonald (domhnall) 2019-04-01 18:37:47 UTC
(https://nvd.nist.gov/vuln/detail/CVE-2019-10654):
The lzo1x_decompress function in liblzo2.so.2 in LZO 2.10, as used in Long Range Zip (aka lrzip) 0.631, allows remote attackers to cause a denial of service (invalid memory read and application crash) via a crafted archive, a different vulnerability than CVE-2017-8845.
