漏洞描述
中文描述:
在多个包中使用时,POSIX readdir_r函数存在多个缓冲区溢出,本地用户可以通过(1)利用在opendir和pathcon调用之间的竞态条件的symlink攻击并变更文件系统为一个带有更大最大directtory-entry名字长度的系统,或(2)可能通过程序员引入的有关带有小结构指向的操作系统的错误,如Solaris或BeOS, 发起拒绝服务并可能执行任意代码,如在这些包中,包括(a)gcj,(b)KDE,(c)libwww,(d)Rudiments库,(e)teTeX,(f)xmail,(g)bfbtester,(h)ncftp,(i)netwib,(j)OpenOffice.org,(k)Pike,(l)reprepro,(m)Tcl和(n)xgsmlib。
英文描述:
Multiple buffer overflows in the POSIX readdir_r function, as used in multiple packages, allow local users to cause a denial of service and possibly execute arbitrary code via (1) a symlink attack that exploits a race condition between opendir and pathcon calls and changes the filesystem to one with a larger maximum directory-entry name length, or (2) possibly via programmer-introduced errors on operating systems with a small struct dirent, such as Solaris or BeOS, as demonstrated in packages including (a) gcj, (b) KDE, (c) libwww, (d) the Rudiments library, (e) teTeX, (f) xmail, (g) bfbtester, (h) ncftp, (i) netwib, (j) OpenOffice.org, (k) Pike, (l) reprepro, (m) Tcl, and (n) xgsmlib.
