USN-5292-4: snapd regression

Read Time:55 Second

USN-5292-1 fixed a vulnerability in snapd. Unfortunately that update introduced
a regression that could break the fish shell. This update fixes the problem.

We apologize for the inconvenience.

Original advisory details:

James Troup discovered that snap did not properly manage the permissions for
the snap directories. A local attacker could possibly use this issue to expose
sensitive information. (CVE-2021-3155)

Ian Johnson discovered that snapd did not properly validate content interfaces
and layout paths. A local attacker could possibly use this issue to inject
arbitrary AppArmor policy rules, resulting in a bypass of intended access
restrictions. (CVE-2021-4120)

The Qualys Research Team discovered that snapd did not properly validate the
location of the snap-confine binary. A local attacker could possibly use this
issue to execute other arbitrary binaries and escalate privileges.
(CVE-2021-44730)

The Qualys Research Team discovered that a race condition existed in the snapd
snap-confine binary when preparing a private mount namespace for a snap. A
local attacker could possibly use this issue to escalate privileges and
execute arbitrary code. (CVE-2021-44731)

New Wiper Malware Discovered Targeting Ukrainian Interests

Read Time:1 Minute, 22 Second

FortiGuard Labs is aware of new wiper malware observed in the wild attacking Ukrainian interests. The wiper was found by security researchers today at ESET. Various estimates from both outfits reveal that the malware wiper has been installed on several hundreds of machines within the Ukraine. Cursory analysis reveals that wiper malware contains a valid signed certificate that belongs to an entity called “Hermetica Digital” based in Cyprus. This is a breaking news event. More information will be added when relevant updates are available. For further reference about Ukrainian wiper attacks please reference our Threat Signal from January. Also, please refer to our most recent blog that encompasses the recent escalation in Ukraine, along with salient advice about patch management and why it is important, especially in today’s political climate. Is this the Work of Nobelium/APT29?At this time, there is not enough information to correlate this to Nobelium/APT29 or nation state activity. Are there Other Samples Observed Using the Same Certificate?No. Cursory analysis at this time highlights that the Hermetica Digital certificate used by this malware sample is the only one that we are aware of at this time. Was the Certificate Stolen?Unknown at this time. As this is a breaking news event, information is sparse. Why is the Malware Signed?Malware is often signed by threat actors as a pretence to evade AV or any other security software. Signed malware allows for threat actors to evade and effectively bypass detection and guaranteeing a higher success rate. What is the Status of Coverage?FortiGuard Labs has AV coverage in place for publicly available samples as:W32/KillDisk.NCV!tr
