Alpine Linux: ack fixed in 3.10.0-r0

AnalysisAI

Improper neutralization of terminal control/escape sequences in ack (App::Ack), the Perl-based grep-like source-code search tool by Andy Lester, is fixed in v3.10.0 and affects all prior releases (App::Ack 0 through ≤3.10.0). When ack prints matching lines from attacker-controlled files, unsanitized control/meta sequences are passed through to the terminal, which per the CVSS vector (A:H) can disrupt or hang the terminal session and is separately tagged as an information-disclosure risk. …
