IBM QRadar SIEM 7.5.x < 7.5.0 UP15 IF03 Multiple Vulnerabilities

critical Nessus Plugin ID 318676

Language:

Synopsis

The remote IBM QRadar SIEM host is affected by multiple vulnerabilities.

Description

According to its self-reported version, the IBM QRadar SIEM installation on the remote host is 7.5.x prior to 7.5.0 Update Pack 15 Interim Fix 03. It is, therefore, affected by multiple vulnerabilities:

 - XML::Parser versions through 2.47 for Perl has an off-by-one heap buffer overflow in st_serial_stack that can cause heap corruption and crashes when parsing XML with very deep element nesting.
 (CVE-2006-10003)

 - In the Linux kernel, a heap overflow vulnerability exists in the nfsd subsystem that allows a remote attacker to execute arbitrary code or cause a denial of service. (CVE-2026-31402)

 - A use-after-free was possible in the Python lzma.LZMADecompressor, bz2.BZ2Decompressor, and gzip.GzipFile when a memory allocation fails with a MemoryError and the decompression instance is re-used. (CVE-2026-6100)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update IBM QRadar SIEM to version 7.5.0 Update Pack 15 Interim Fix 03 or later.
