Jean-Sebastien Guay-Lero has reported a vulnerability in file, which
potentially can be exploited by malicious people to compromise a vulnerable
system.
The vulnerability is caused due to an unspecified integer underflow
within the "file_printf" function, which can be exploited to cause a
heap-based buffer overflow.
versions < 4.20 are vulnerable.
Arches, please stabilize sys-apps/file-4.20. Thanks.
just a note. that file-4.20 does not compile on uClibc (non posix regex
defines) It introduces new features which our team has yet had time to review.
A backported fix might be better
It will compile with a small patch that adds.
#ifndef REG_STARTEND
# define REG_STARTEND (1 << 2)
#endif
No uclibc for HPPA, so I keyworded 4.20.
no uclibc on ppc64 either, so stable there, too.
no uclibc on alpha, no cookie.
4.20 stable anyway.
emerges fine and works on amd64, not sure about that uclibc thingy since
there's only uclibc++ on amd64

dont worry about the uclibc profile, it will be accounted for ... stabilize for
glibc/default-linux as normal
thanks arches, ready for glsa.
GLSA 200703-26, thanks to everybody!
