Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-libs/libpcre < 8.40-r1 >= 8.40-r1 Description =========== It was found that the compile_bracket_matchingpath function in pcre_jit_compile.c in PCRE library is vulnerable to an out-of-bounds read. Impact ====== A remote attacker could possibly cause a Denial of Service condition via a special crafted regular expression. Workaround ========== There is no known workaround at this time.
