The vulnerability is caused due to a boundary error within the "intT1_EnvGetCompletePath()" function in lib/t1lib/t1env.c. This can be exploited to cause a buffer overflow when an application processes an overly long string in the "FileName" parameter. The vulnerability is reported in version 5.1.1. Other versions may also be affected. py@gentoo.org 2007-09-22 18:11:56 0000 Advisory mentions 5.1.1, but our last version (5.0.2) is also affected. Ubuntu released a patch for this: http://security.ubuntu.com/ubuntu/pool/main/t/t1lib/t1lib_5.1.0-2ubuntu0.6.06.1.diff.gz The relevant part should be: --------------------------------------------------- --- t1lib-5.1.0.orig/lib/t1lib/t1env.c +++ t1lib-5.1.0/lib/t1lib/t1env.c @@ -611,6 +611,12 @@ #endif strcat( pathbuf, DIRECTORY_SEP); /* And finally the filename: */ + /* If current pathbuf + StrippedName + 1 byte for NULL is bigger than pathbuf + let's try next pathbuf */ + if( strlen(pathbuf) + strlen(StrippedName) + 1 > sizeof(pathbuf) ) { + i++; + continue; + } strcat( pathbuf, StrippedName); /* Check for existence of the path: */ ---------------------------------------------------- Fonts, please provide an updated ebuild. and maybe combine this with bug 130362. dirtyepic@gentoo.org 2007-09-22 19:13:37 0000 media-libs/t1lib-5.0.2-r1 and t1lib-5.1.1 are in the tree. 5.0.2-r1 is the target for stabilization. thanks. rbu@gentoo.org 2007-09-22 19:43:05 0000 Ubuntu mentions CVE-2007-4033 with this bug, but I doubt that is correct. If so, we should request a name for this issue. Thanks Ryan. Arches, please test and mark stable media-libs/t1lib-5.0.2-r1.
