EulerOS 2.0 SP11 : coreutils (EulerOS-SA-2026-4218)

low Nessus Plugin ID 364838

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the versions of the coreutils packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 GNU coreutils unexpand is vulnerable to a heap-based buffer overflow due to an integer overflow during buffer allocation when processing large tab stop (-t) values. The multiplication used to calculate the allocation size can wrap around, resulting in an undersized buffer.
 When processing crafted input, subsequent writes exceed the allocated memory, leading to an outofbounds heap write.

 When running GNU coreutils unexpand with attacker-provided large tab stop (-t) arguments, this behavior leads to a crash and potentially achieve a heap write primitive depending on memory layout.










 This issue has been fixed in the commit b60a159fdc5bfcf9988d3a4cb6f53abe8ad5d35d(CVE-2026-56392)

Tenable has extracted the preceding description block directly from the EulerOS coreutils security advisory.

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

Solution

Update the affected coreutils packages.
