慎思所愿

帖于二零二六年五月廿三日,晚七时二十分(世界时,周六)由chmod(订阅者,#169510)
所发 简复:慎思所愿(cyperpunks)
父帖:基于GTK之PDF阅读器多存隐患__JHSNS_SEG_c3e39d87_9__

吾不谓.note.gnu.build-id与安危相干也。 此乃为调试剖析而设,用以索检ELF二进制/调试信息/源码之钥, 例如可借此查询debuginfod。 纵于寻常之用,亦非与ELF内容以密码相系,可随机或由用户所控, 例如

echo 'int main() { return 42; }' |gcc -xc - -Wl,--build-id=0x0123456789012345678901234567890123456789
吾所知者,唯需置九"魔法"字节耳%PDF-1.4于ELF/PDF之首1024字节中。吾料除此构建标识外,尚有他种可能,如他项注记,或仅存于ELF段落之间。
