Noroxi assessment

Priority: Monitor (action score 23/100)

  • Public proof-of-concept code exists (Exploit-DB); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 10.8% (FIRST EPSS); higher than 95.9% of all records.
  • No special conditions are required; it is repeatable.
  • Fixed version: kernel-image-2.4.18-1-alpha (Debian:3.0) 2.4.18-8; kernel-image-2.4.18-1-i386 (Debian:3.0) 2.4.18-9; kernel-image-2.4.18-i386bf (Debian:3.0) 2.4.18-5woody2.

Low priority for now. Upgrade to kernel-image-2.4.18-1-alpha (Debian:3.0) 2.4.18-8; kernel-image-2.4.18-1-i386 (Debian:3.0) 2.4.18-9; kernel-image-2.4.18-i386bf (Debian:3.0) 2.4.18-5woody2 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Integer signedness error in the decode_fh function of nfs3xdr.c in Linux kernel before 2.4.21 allows remote attackers to cause a denial of service (kernel panic) via a negative size value within XDR data of an NFSv3 procedure call.
