minus-squareflying_sheep@lemmy.mllinkfedilinkarrow-up13·6 months agoNo, read the link you posted: Arch does not directly link openssh to liblzma, and thus this attack vector is not possible. You can confirm this by issuing the following command: ldd "$(command -v sshd)" However, out of an abundance of caution, we advise users to remove the malicious code from their system by upgrading either way.
minus-squareprogandy@feddit.delinkfedilinkarrow-up5arrow-down2·edit-26 months agoI think that was a precaution. The malicious build script ran during the build, but the backdoor itself was most likely not included in the resuling package as it checked for specific packaging systems. https://www.openwall.com/lists/oss-security/2024/03/29/22
