Short explanation
DateTime-Lite versions before 0.8.1 allow CPU exhaustion via a per-day loop when adding seconds [S0].
Attackers who control the number of added seconds can keep the process busy for as long as they choose, causing a denial of service [S0].
What should be done?
- Follow vendor advisories [S0]
Chain of evidence and sources
DateTime-Lite 0.8.1 öncesi sürümler saniye ekleme işleminde CPU tükenmesine neden olur [S0].
_normalize_leap_seconds fonksiyonu gün sınırlarını tek gün olarak aşar ve iterasyon sınırı bulunmaz [S0].
Show the technical text from the sources
DateTime::Lite versions before 0.8.1 for Perl allow CPU exhaustion via a per-day loop when adding seconds. _normalize_leap_seconds crosses day boundaries one day at a time, so add(seconds => $n) on an object with a non-floating time zone takes about |$n|/86400 iterations, and nothing limits $n. The XS implementation and the pure-Perl fallback both have the loop. An attacker who controls the number of seconds added can keep the process busy for as long as they choose.
