RPM 4.4.x through 4.9.x, probably before 4.9.1.2, allows remote attackers to cause a denial of service (memory corruption) and possibly execute arbitrary code via an rpm package with crafted headers and offsets that are not properly handled when a package is queried or installed, related to (1) the regionSwab function, (2) the headerLoad function, and (3) multiple functions in rpmio/rpmpgp.c.
lib/fsm.c in RPM before 4.4.3 does not properly reset the metadata of an executable file during deletion of the file in an RPM package removal, which might allow local users to gain privileges by creating a hard link to a vulnerable (1) setuid or (2) setgid file, a related issue to CVE-2010-2059.
