CVE-2002-0391: Integer overflow in xdr_array function in RPC servers for operating systems that use libc, glibc, or other code based on SunRPC including…

CriticalCVSS 9.8 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Plan (action score 56/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 58.1% (FIRST EPSS); higher than 99.1% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: acm (Debian:12) 5.0-10; dietlibc (Debian:12) 0.20-0cvs20020808; glibc (Debian:12) 2.2.5-13.

Add it to your regular patch cycle. Upgrade to acm (Debian:12) 5.0-10; dietlibc (Debian:12) 0.20-0cvs20020808; glibc (Debian:12) 2.2.5-13 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Integer overflow in xdr_array function in RPC servers for operating systems that use libc, glibc, or other code based on SunRPC including dietlibc, allows remote attackers to execute arbitrary code by passing a large number of arguments to xdr_array through RPC services such as rpc.cmsd and dmispd.
