CVE-2008-5352: Integer overflow in the JAR unpacking utility (unpack200) in the unpack library (unpack.dll) in Java Runtime Environment (JRE) for Sun JDK…

CriticalCVSS 9.3 · v2.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 38/100)

  • 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: 3% (FIRST EPSS); higher than 87.8% of all records.
  • Fixed version: java-1.5.0-ibm (Red Hat:rhel_extras:4) 1:1.5.0.9-1jpp.4.el4; java-1.5.0-ibm-demo (Red Hat:rhel_extras:4) 1:1.5.0.9-1jpp.4.el4; java-1.5.0-ibm-devel (Red Hat:rhel_extras:4) 1:1.5.0.9-1jpp.4.el4.

Low priority for now. Upgrade to java-1.5.0-ibm (Red Hat:rhel_extras:4) 1:1.5.0.9-1jpp.4.el4; java-1.5.0-ibm-demo (Red Hat:rhel_extras:4) 1:1.5.0.9-1jpp.4.el4; java-1.5.0-ibm-devel (Red Hat:rhel_extras:4) 1:1.5.0.9-1jpp.4.el4 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Integer overflow in the JAR unpacking utility (unpack200) in the unpack library (unpack.dll) in Java Runtime Environment (JRE) for Sun JDK and JRE 6 Update 10 and earlier, and JDK and JRE 5.0 Update 16 and earlier, allows untrusted applications and applets to gain privileges via a Pack200 compressed JAR file that triggers a heap-based buffer overflow.
