Name of the Vulnerable Software and Affected Versions Apache Traffic Server versions 8.0.0 through 8.1.9 Apache Traffic Server versions 9.0.0 through 9.2.14 Apache Traffic Server versions 10.0.0 through 10.1.3

Description Apache Traffic Server updates the HTTP/2 HPACK dynamic table before confirming the header block encoded successfully. Consequently, an encode failure causes the encoder to become out of sync with the peer decoder, leading to the corruption of subsequent header blocks on the connection.

Recommendations Upgrade versions 8.0.0 through 8.1.9 and 9.0.0 through 9.2.14 to version 9.2.15. Upgrade versions 10.0.0 through 10.1.3 to version 10.1.4.
