Vulnerability from csaf_redhat - Published: 2005-04-12 13:56 - Updated: 2005-04-12 00:00
Summary
Red Hat Security Advisory: gaim security update
Severity
Important
Notes
Topic: An updated gaim package that fixes multiple denial of service issues is now available. This update has been rated as having important security impact by the Red Hat Security Response Team.
Details: The Gaim application is a multi-protocol instant messaging client. A buffer overflow bug was found in the way gaim escapes HTML. It is possible that a remote attacker could send a specially crafted message to a Gaim client, causing it to crash. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-0965 to this issue. A bug was found in several of gaim's IRC processing functions. These functions fail to properly remove various markup tags within an IRC message. It is possible that a remote attacker could send a specially crafted message to a Gaim client connected to an IRC server, causing it to crash. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-0966 to this issue. A bug was found in gaim's Jabber message parser. It is possible for a remote Jabber user to send a specially crafted message to a Gaim client, causing it to crash. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-0967 to this issue. In addition to these denial of service issues, multiple minor upstream bugfixes are included in this update. Users of Gaim are advised to upgrade to this updated package which contains Gaim version 1.2.1 and is not vulnerable to these issues.

CVE-2005-0965

The gaim_markup_strip_html function in Gaim 1.2.0, and possibly earlier versions, allows remote attackers to cause a denial of service (application crash) via a string that contains malformed HTML, which causes an out-of-bounds read.

CVE-2005-0966

The IRC protocol plugin in Gaim 1.2.0, and possibly earlier versions, allows (1) remote attackers to inject arbitrary Gaim markup via irc_msg_kick, irc_msg_mode, irc_msg_part, irc_msg_quit, (2) remote attackers to inject arbitrary Pango markup and pop up empty dialog boxes via irc_msg_invite, or (3) malicious IRC servers to cause a denial of service (application crash) by injecting certain Pango markup into irc_msg_badmode, irc_msg_banned, irc_msg_unknown, irc_msg_nochan functions.

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

Nomenclature

  • Seen: The vulnerability was mentioned, discussed, or observed by the user.
  • Confirmed: The vulnerability has been validated from an analyst's perspective.
  • Published Proof of Concept: A public proof of concept is available for this vulnerability.
  • Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
  • Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
  • Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
  • Not confirmed: The user expressed doubt about the validity of the vulnerability.
  • Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
