Symantec cannot handle SHA-2 and breaks Windows 7 and Server 2008 R2

Picture: Microsoft

If solely Symantec had any sort of forewarning about Microsoft shifting to make use of SHA-2 signed updates, all the things might need gone smoother.

Plainly six months will not be sufficient for Symantec to get its geese in a row, as its anti-virus software program is unable to deal with SHA-2 signatures, and led to Microsoft withholding updates from sure gadgets.

In an update note for Home windows 7 and Server 2008 R2, Microsoft stated that when a tool runs any Symantec or Norton antivirus program, and makes an attempt to put in an replace signed solely with SHA-2, the antivirus program blocks or deletes the replace throughout set up, which may make the working system cease working.

For its half, Symantec said an “upcoming model” of Symantec Endpoint Safety would help SHA-2.

Earlier within the yr, Microsoft stated it was shifting away from dual-signing its updates with SHA-1 and SHA-2 because of the weak point of SHA-1.

“Sadly, the safety of the SHA-1 hash algorithm has turn out to be much less safe over time because of weaknesses discovered within the algorithm, elevated processor efficiency, and the arrival of cloud computing,” Microsoft said on the time.

“Stronger alternate options such because the Safe Hash Algorithm 2 (SHA-2) are actually strongly most popular as they don’t undergo from the identical points.”

Final week, Broadcom picked up Symantec’s enterprise safety enterprise in addition to the Symantec model identify for $10.7 billion.

The remaining portion of Symantec will maintain its client merchandise, reminiscent of Norton.
