5.0 MEDIUM — AV:N/AC:L/Au:N/C:N/I:N/A:P

Description

Perl-Compatible Regular Expression (PCRE) library before 7.3 does not properly compute the length of (1) a \p sequence, (2) a \P sequence, or (3) a \P{x} sequence, which allows context-dependent attackers to cause a denial of service (infinite loop or crash) or execute arbitrary code.

Affected configurations

• pcre pcre (<= 6.0) • pcre pcre (<= 6.1) • pcre pcre (<= 7.3)
