EulerOS 2.0 SP15 : libsolv (EulerOS-SA-2026-2934)

medium Nessus Plugin ID 332899

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

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

 A flaw was found in libsolv. This stack-based buffer overflow vulnerability occurs in libsolv's Debian metadata parser when processing specially crafted Debian repository metadata. An attacker could exploit this by providing malicious SHA384 or SHA512 checksum tags, leading to memory corruption and a denial of service (DoS) in the affected system.(CVE-2026-9150)

 A flaw was found in libsolv. This heap buffer overflow vulnerability occurs when a victim processes a specially crafted `.solv` file containing negative size values in the `repo_add_solv` function. This leads to an undersized memory allocation and a subsequent out-of-bounds write. An attacker could exploit this to cause a denial of service (DoS).(CVE-2026-9149)

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

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

Solution

Update the affected libsolv packages.
