Security Bulletin: Multiple vulnerabilities in IBM Java SDK affect AIX
===============================================================================
SUMMARY:
There are multiple vulnerabilities in IBM SDK Java Technology Edition,
Version 8 used by AIX. AIX has addressed the applicable CVEs.
===============================================================================
VULNERABILITY DETAILS:
CVEID: CVE-2024-21217
https://www.cve.org/CVERecord?id=CVE-2024-21217
DESCRIPTION: Vulnerability in Java SE (component: Serialization).
Difficult to exploit vulnerability allows unauthenticated attacker
with network access via multiple protocols to compromise Java SE.
Successful attacks of this vulnerability can result in unauthorized
ability to cause a partial denial of service (partial DOS).
CVSS Base Score: 3.7
CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L)
CVEID: CVE-2024-21208
https://www.cve.org/CVERecord?id=CVE-2024-21208
DESCRIPTION: Vulnerability in Java SE (component: Networking).
Difficult to exploit vulnerability allows unauthenticated attacker
with network access via multiple protocols to compromise Java SE.
Successful attacks of this vulnerability can result in unauthorized
ability to cause a partial denial of service (partial DOS).
CVSS Base Score: 3.7
CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L)
CVEID: CVE-2024-10917
https://www.cve.org/CVERecord?id=CVE-2024-10917
DESCRIPTION: In Eclipse OpenJ9 versions up to 0.47, the JNI function
GetStringUTFLength may return an incorrect value which has wrapped
around. From 0.48 the value is correct but may be truncated to
include a smaller number of characters.
CVSS Base Score: 5.3
CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N)
AFFECTED PRODUCTS AND VERSIONS:
AIX 7.2, 7.3
VIOS 3.1, 4.1
The vulnerabilities in the following filesets are being addressed:
key_fileset = java
Fileset Lower Level Upper Level KEY
---------------------------------------------------------
Java8.jre 8.0.0.0 8.0.0.830 key_w_fs
Java8.sdk 8.0.0.0 8.0.0.830 key_w_fs
Java8_64.jre 8.0.0.0 8.0.0.830 key_w_fs
Java8_64.sdk 8.0.0.0 8.0.0.830 key_w_fs
Note: To find out whether the affected Java filesets are installed
on your systems, refer to the lslpp command found in AIX user's guide.
Example: lslpp -L | grep -i java
REMEDIATION:
A. FIXES
AIX and VIOS fixes are available.
The latest level of Java is available from Fix Central:
32-bit: https://www-945.ibm.com/support/fixcentral/swg/selectFixes?parent=ibm~WebSphere&product=ibm/IBM+SDKs+for+Java+Technology/Java+Standard+Edition+%28Java+SE%29&release=8.0.0.0&platform=AIX+32-bit,+pSeries&function=all
64-bit: https://www-945.ibm.com/support/fixcentral/swg/selectFixes?parent=ibm~WebSphere&product=ibm/IBM+SDKs+for+Java+Technology/Java+Standard+Edition+%28Java+SE%29&release=8.0.0.0&platform=AIX+64-bit,+pSeries&function=all
The AIX and VIOS fixes can be downloaded via https from:
https://aix.software.ibm.com/aix/efixes/security/java_apr2025_fix.tar
The link above is to a tar file containing this signed
advisory, fix packages, and OpenSSL signatures for each package.
The fixes below include prerequisite checking. This will
enforce the correct mapping between the fixes and AIX
Technology Levels.
Java Fix (*.Z) KEY
---------------------------------------------------------
8.0.0 java8_32_installp_8.0.0.35.tar key_w_fix
8.0.0 java8_64_installp_8.0.0.35.tar key_w_fix
To extract the fixes from the tar file:
tar xvf java_apr2025_fix.tar
cd java_apr2025_fix
Verify you have retrieved the fixes intact:
The checksums below were generated using the
"openssl dgst -sha256 [filename]" command as the following:
openssl dgst -sha256 filename KEY
-----------------------------------------------------------------------------------------------------------------
2e5096bbb4548c4019762f9d545650dd4fdd4227b95af10bfb094d2c6662eae3 java8_32_installp_8.0.0.35.tar key_w_csum
6bdb571272b709f1a6c9491716f5ef6e3c9db2d19d53638b592212b40b95dc53 java8_64_installp_8.0.0.35.tar key_w_csum
These sums should match exactly. The OpenSSL signatures in the tar
file and on this advisory can also be used to verify the
integrity of the fixes. If the sums or signatures cannot be
confirmed, contact IBM Support at
http://ibm.com/support/ and describe the discrepancy.
openssl dgst -sha256 -verify [pubkey_file] -signature [advisory_file].sig [advisory_file]
openssl dgst -sha256 -verify [pubkey_file] -signature [ifix_file].sig [ifix_file]
Published advisory OpenSSL signature file location:
https://aix.software.ibm.com/aix/efixes/security/java_apr2025_advisory.asc.sig
B. FIX AND INTERIM FIX INSTALLATION
If possible, it is recommended that a mksysb backup of the system
be created. Verify it is both bootable and readable before
proceeding.
To preview a fix installation:
installp -a -d fix_name -p all # where fix_name is the name of the
# fix package being previewed.
To install a fix package:
installp -a -d fix_name -X all # where fix_name is the name of the
# fix package being installed.
WORKAROUNDS AND MITIGATIONS:
None.
