Alpine: multiple singularity packages: security update to 4.3.5-r0
medium Tenable Cloud Security Plugin ID 436247
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- SingularityCE and SingularityPRO are open source container platforms. Prior to SingularityCE 4.3.5 and
SingularityPRO 4.1.11 and 4.3.5, if a user relies on LSM restrictions to prevent malicious operations
then, under certain circumstances, an attacker can redirect the LSM label write operation so that it is
ineffective. The attacker must cause the user to run a malicious container image that redirects the mount
of /proc to the destination of a shared mount, either known to be configured on the target system, or that
will be specified by the user when running the container. The attacker must also control the content of
the shared mount, for example through another malicious container which also binds it, or as a user with
relevant permissions on the host system it is bound from. This vulnerability is fixed in SingularityCE
4.3.5 and SingularityPRO 4.1.11 and 4.3.5. (CVE-2025-64750)
